    DRAIN PIPE CONNECTION DEVICE AND DIVERTER DEVICE
    The present, invention relates to a drain pipe connection device for being connected to a drain pipe, and to a diverter device for diverting a liquid, such, as rainwater, from the drain pipe. In particular, the diverter device is suited to divert rainwater from a drain pipe connected to a sewer system.
    In order to avoid flooding in developed real estate at unwanted locations such as pavements and streets, rainwater is usually collected and led into rainwater drain pipes. Further, it is a long-standing practice to connect such rainwater drain pipes to the sewer system. This is done with a drain pipe connection device which is connected on a drain pipe leading to the sewer system and on the other end directly or indirectly to a rainwater drain pipe. The sewer system is consequently sometimes referred to as a sewer system or 'mixed type' as it both drains sewage water and rainwater.
    Competitive to serving the purpose of draining rainwater, rainwater drain pipes are usually also used to equalize occurring pressure, differences between the sewer system and the outside atmosphere. In other words, the rainwater drain pipes are also used to vent the sewer system.
    A problem associated with a sewer system or mixed type is that overflows may occur, and that this overflow may be extremely unpleasant. For example. during a period of particularly heavy rainfall, the sewers may become overloaded and, eventually, may overflow. Sewage fluids may, hence, leak out into the open. At sausage, liquid contaminated with faeces may flood pavements and streets.
    If one simply detaches the rainwater drain pipe from the sewer system and leads the rainwater out into the open next to the buildings, pavements and streets next to buildings may become flooded. Further, replacing the described connections between rainwater pipes and drain pipes leading to the sewers, i.e., a potential restructuring of the pipe systems in and around buildings should preferably not turn out to be a time-consuming and costly task.
    There is, hence, a need for a drain pipe connection device which addresses at least one of the shortcomings mentioned above. More generally, there is a need for a device and / or method which addresses at least one of the aforementioned shortcomings associated with mixed sewer systems.
    Embodiments are defined by the claims below.
    GENERAL DESCRIPTION
    One aspect of this disclosure relates to a drain pipe connection device with an outer pipe piece and an inner pipe piece. Basically, the outer pipe piece may serve as a flow path for a first fluid such as rainwater. inner pipe piece may serve as an independent and separate flow path for a second fluid such as air and. gas flowing back, and forth in the course of venting the sewers.
    The outer pipe piece has a pipe wall and comprises an inlet end for being connected to some pipe piece as well as an outlet end for being connected to a rainwater discharge pipe.
    For example, rainwater may flow into the outer pipe piece through the inlet end and may then be led through the outer pipe piece, out of the outlet end, and into a rainwater discharge pipe.
    The inner pipe piece is at least partially located within the outer pipe piece. Preferably, the inner pipe piece is partially located within the outer pipe piece. The inner pipe piece further penetrates the pipe wall or the outer pipe piece. The inner pipe piece further comprises a drain pipe connection end for being connected to a drain pipe and an aeration end for being connected to a separate inner pipe piece with an aeration element.
    As the inner pipe piece is located within the outer pipe piece, a fluid, such as air and / or some other gas (es) may flow through the inner pipe piece separately from a fluid flowing inside of the outer pipe piece but outside of the inner pipe piece. As the inner pipe piece penetrates the pipe wall of the outer pipe piece, the two pipe pieces may, for example, start-off substantially concentrically at one end whereas their other ends may point into different directions,
    In fact, there is an angle between the outlet end of the outer pipe piece and the drain pipe connection end of the inner pipe piece. The presence of the angle means that the outlet end of the outer pipe piece and the drain pipe connection end of the inner pipe piece are not oriented in the same direction.
    Preferably, there is no angle between the inlet end of the outer pipe piece and the aeration connection end of the inner pipe piece. It is also preferable for the inner pipe piece to be located concentrically within the outer pipe piece and near the inlet end and the aeration connection end, respectively.
    If there is an angle between the outlet end of the outer pipe piece and the drain pipe connection end of the inner pipe piece, two pipe ends oriented .in different directions may be conveniently connected to these ends. For example, a drain pipe connected to the sewer system may be connected to the drain pipe connection while being oriented substantially vertically, a rainwater discharge pipe may be connected to the outlet end while being oriented at an angle deviating from the vertical direction.
    The described embodiment of a drain pipe connection device allows separating rainwater from the sewer system by leading it through the outer pipe piece and leading it into a pipe extending at an angle with respect to the drain pipe leading to the sewer system. Further, the drain pipe connection device may be conveniently used to replace existing drain pipe connection devices. Thus, the problem of an overflowing sewer system during periods of heavy rain fall is efficiently prevented without requiring a large amount of time-consuming and costly restructuring of the pipe systems in and around buildings.
    Preferably, the drain pipe connection device is used underground, i.e., beneath surface level.
    connection device is further preferably made i.e., there are preferably no connection separately produced parts are connected during (e.g., no welding zone). Preferably, the drain
    The drain pipe as one piece, portions where manufacturing pipe connection device is made of PVC (polyvinyl chloride). However, it can, if desired for a particular purpose of use, for example, instead of be made or other suitable materials such as PS (polyethylene) or PP (polypropylene). The drain pipe connection device may further be fully recyclable.
    The pipe piece to be connected to the inlet end of the outer pipe piece may be a part of a rainwater pipe connection device for being connected to a rainwater pipe or it may be another pipe piece mediating between a rainwater pipe connection device and the inlet end .
    The outer pipe piece and the inner pipe piece may be used to provide separate fluid flow paths for two fluids. The first fluid may, eg, be rainwater being drained into a rainwater discharge pipe, separate from the sewer system, and, for example, leading to a suitable spot for being discharged (eg, above ground level), say at a distance of twenty meters from a building. The second fluid may be air / gas flowing in or out of the sewer system as a part of a pressure equalization taking place as the sewer system is being vented.
    When the outer pipe piece is used to transport rainwater, the rainwater is diverted from the drain pipe leading to the sewer system in the sense that no rainwater, or, depending on the version, at least less rainwater, enters the inner pine piece and, hence, the drain
    ..eadinq to the sewer system,
    Sven although rain water is diverted from the sewer system when relying on the described drain pipe connection device, pressure differences between sewer pipes and the outside may be equalized, or at least reduced, through the aeration connection end of the inner pipe piece.
    The disclosure also relates to an embodiment of a drain pipe connection device which is very similar to the one previously described. The only difference between this embodiment and the formerly described type is that the inner pipe piece comprises an aeration end instead of an aeration connection end. The inner pipe piece itself comprises an aeration element for reducing a pressure difference between inside and outside of the inner pipe piece. The aeration element may, e.g., be part of the aeration end. Put differently, the inner pipe piece is not configured to be connected to an additional (inner) pipe piece which separately comprises an aeration element but. the aeration element.
    Inner pipe piece itself comprises the
    In other words, the drain pipe connection device according to this type of embodiment also includes an outer pipe piece and an inner pipe piece. The outer pipe piece has an inlet end for being connected to a pipe piece and an outlet end for being connected to a rainwater discharge pipe. The inner pipe piece is at least partially (preferably partially) located within the outer pipe piece and penetrates the pipe wall of the outer pipe piece. The inner pipe piece comprises a drain pipe connection end for being connected to a drain pipe and an aeration end and an aeration element for reducing a pressure difference between inside and outside of the inner pipe piece. Further, there is an angle between the outlet end of the outer pipe piece and the drain pipe connection end of the inner pipe piece.
    This type of drain pipe connection device is especially compact as no extension pipe piece with an aeration element is needed.
    Preferably, the aeration comprises the aeration element.
    The aeration element is for reducing a pressure difference between the inside and outside of the inner pipe piece. The reduction may be partial or complete, i.e., a pressure equalization. Partial pressure reduction may be effected if the aeration element is, e.g., a two-way valve which opens if the pressure difference exceeds a chosen threshold. A complete equalization may, for example, be effected if the aeration element always provides a fluid communication between inside and outside of the inner pipe piece.
    Preferably, the prevent a liquid piece when the vertically with aeration element is configured so as to from entering from above into the inner pipe inner pipe piece is substantially the aeration element being located at the top end side.
    In the following, preferred aspects of the drain pipe connection device according to any one of the previously described, will be described. These preferable features may be realized for any or previously addressed expired or drain pipe connection devices and freely mutually and. cumulatively combined unless otherwise indicated or when the contrary becomes apparent from the context. In particular, the preferable aspects may be combined with both the type of drain pipe connection device with an inner pipe piece with or ’without an aeration element. In other words, the preferable aspects can be combined with the type of the inner pipe piece including an aeration connection end as well as with the type of the inner pipe piece comprising an aeration end.
    The angle between the outlet end of the outer pipe piece and the drain pipe connection end of the inner pipe piece may be an angle between a central axis or the outlet end and a central axis of the inner pipe piece. The inner and outer pipe pieces preferably include substantially round cross sections and the central axis goes through the center points or circular cross sections, respectively. The outlet end and the drain pipe connection are the respective end pipe pieces, and the central, axes are the end axes of these pipe pieces, respectively.
    The angle is preferably the angle between the central axes extending through and perpendicular to the (preferably circle shaped) end surfaces of the inner and outer pipe pieces, respectively.
    According to a preferred embodiment, the angle is in a range or 45 ° to 135 °. More preferably, the angle is in a range of
    60 ° to 120 °, 60 ° to 3 °, 60 ° to 100 °, and even more preferably or 80 ° to 100 °. It is most preferable if the angle is substantially (or even precisely) 90 °. Angles close to 90 ° allow an especially convenient connection of the drain pipe to the inner pipe piece and of a rainwater discharge pipe to the outer pipe piece.
    Preferably, the inner pipe piece is substantially straight, and more preferably it is straight. This simplifies the construction and increases manufacturing efficiency.
    Preferably, the outer pipe piece comprises a curved portion. The curved portion is a possibility to realize the presence of the angle between the outlet end of the outer pipe piece and the drain pipe connection end of the inner pipe piece. Further, the curved portion minimizes losses in fluid flow speed velocities in the inner and outer pipe pieces due to minimizing frictional losses. This is especially useful for efficient drainage or rainwater through the outer pipe piece. Moreover, the inner pipe piece preferably penetrates the pipe wall or the outer pipe piece at the curved portion. The penetration zone in which the outer and inner pipe pieces are connected also holds the inner pipe in a fixed position with respect to the outer pipe piece.
    However, according to another aspect, the angle between the outlet end of the outer pipe piece and the drain pipe connection end of the inner pipe piece is realized differently, i.e., without the outer pipe piece having a curved portion. For example, the outer pipe piece may contain several straight portions connected to each other at angles which add up to the mentioned angle between the outlet end and the drain pipe connection end,
    Preferably, a central axis or the curved portion has the shape of a quarter of a circle. However, the disclosure also relates to other differently the central axis has the shape of any other part of a circle, eg ,, more or less than a quarter. When the outer pipe piece has a round crosssectional shape, the circumference walls of these, then, have the shape or a part of a circle in a side view.
    Concerning the drain containing an aeration end with an aeration element nreferah includes preventing a liquid from entering the pipe connection device aeration element, the a covering element for inner pipe piece.
    The covering element may be a member.
    The covering element may, for example, be located on top of a substantially straight inner pipe piece ('when the innex * pipe piece is oriented substantially vertically) so as to prevent rainwater from flowing into the inner pipe piece. The rainwater instead flows along the zone inside of the outer pipe piece but outside of the innex * pipe piece.
    It is further preferable for the aeration element to include an opening for allowing a fluid communication between inside and outside of the inner pipe piece. The opening may be permanently present or it the opening may go back and forth between an open and a closed state, for example, by using a one or a two way valve which opens up when a pressure difference between inside and outside of the inner pipe piece exceeds a pressure threshold value.
    The opening is an easy and convenient possibility to realize a fluid connection for venting the sewer system. The opening may, for example, be a slit, located below a covering element such as a member on top of the innex * pipe piece when the latter is oriented substantially vertically. The opening is used for reducing, or even for equalizing, pressure differences between the sewer system and the outside atmosphere. Preferably, the member (or, more generally, the cover element) or the aeration element is constructed such that it overlaps the respective end of the inner pipe piece a bit, so, that covers a slightly larger surface than a cross-section or the inner pipe piece in order to avoid accidental entering or a liquid such as rainwater flowing through the outer pipe piece into the slit.
    According to some preferred embodiment, the inner pipe piece further comprises a sewer backflow prevention element configured to be transitioned from an open state, in which it permits a fluid flow through the inner pipe piece, to a closed state for preventing a liquid flowing from the drain connection end to the aeration connection end or the aeration end. The sewer backflow prevention element is configured to be transitioned in function or a liquid level rising from the. drain connection end towards the aeration connection end or the aeration end.
    The sewer backflow prevention element prevents sewer liquids from flowing out of the inlet end of the drain pipe connection device. For example, also when the sewers are overloaded, the sewer backflow prevention element prevents sewer liquids from ending up flowing out through a diverter device including the described sewer backflow prevention element, eg, onto a roof or a building etc., etc. the liquid backflow prevention mechanism does not. interfere with the function of pressure equalizations by virtue of, for example, a gaseous fluid flowing out of the inner pipe piece as described above.
    The transition in function of the rising liquid level may be triggered directly through the fluid, or it may be triggered indirectly, eg, by virtue of measuring a liquid level somewhere else (eg, with a sensor) and electronically controlling the opening / closing of the sewer backflow prevention element. The sewer backflow prevention element is preferably also configured to be transitioned from the closed state to the open state, preferably also in function or a liquid level in the inner pipe piece.
    According to some, the sewer backflow prevention element may be implemented in the form of a floatable element {e.g., a ball-shaped member) which may, when floating, constrict the inner pipe piece, preferably, being pressed against a corresponding seat.
    According to some preferred exponent, the sewer backflow prevention element is configured to be closed by the liquid level rising from the drain connection towards the aeration end or the aeration connectioxi end. In other words, preferably the transitioning from open to closed state is directly effected by the liquid level. Preferably, also the transition from closed to open state is effected by the (preferably sinking) liquid level in the inner pipe piece.
    This may, e.g., necessitate the use of an electronic feedback control mechanism.
    Preferably, the sewer backflow prevention element comprises at least one flap configured to rotate so as to shut off a part of or the entire inner pipe upon being lifted and rotated by a rising liquid. In other words, the flap is preferably floatable on a liquid in the inner piece. Preferably, when there is a single flap, the flap is configured to shut off the entire {cross-section of the) inner pipe ciecc According to some preferred embodiment, there may be two flaps provided, each flap preferably being configured to close off at least half of the cross-sectional area of the inner pipe piece so that they together close of the entire cross-section,
    According to some preferred expired, the sewer backflow prevention element comprises a floating device and a receiving part, the floating device being configured to be spaced apart from the receiving part when not floating on a liquid and to brought into contact with the receiving part upon floating on a liquid so as to shut off at least a part of the receiving part. This way, a rising liquid level in the inner pipe piece conveniently effects a transition from an open state to a closed state. Likewise, a sinking liquid level in the inner pipe piece conveniently effects a transition from the closed state to an open state. Of course, there may be partially open and closed states reached in10 between.
    According to some preferred expired, the drain pipe connection device further comprises a shutter device connected to the floating device, the floating device being configured, upon floating on a liquid, to urge the shutting device into a shut state for closing off at least a part or the inner connection pipe piece.
    Preferably, the weight of the floating device pulls open the shutter device when the floating device is not floating. Thus, the sewer backflow prevents means automatically transitions into the open state when no liquid is present in the inner pipe piece. Moreover, it is prevented that the shutter device unintentionally shuts off the inner pipe piece, and it is also prevented that it shuts off too easily.
    The shutter device preferably comprises at least one flap, and the floating device is preferably attached to the least one flap. The disclosure encompasses with one flap, with two flaps, and also including three or more flaps. One or two flaps are especially preferable.
    The disclosure also relates to a pipe piece including a sewer backflow prevention element in accordance with any of the previously described aspects of a sewer backflow prevention element, in other words to a pipe piece which can be connected to an aeration connection end of an inner pipe piece of the type of drain pipe connection device described above with an aeration connection end (rather than an aeration end). The pipe piece comprises an aeration end, an aeration element for reducing a pressure difference between inside and outside of the pipe piece, a connection end for connecting to a drain pipe connection, device, and a sewer backflow prevention element configured to be transitioned from an open state, in which it permits a fluid flow 1 through the inner pipe piece, to a closed state for preventing a liquid flowing from the connection end to the aeration end, the sewer backflow prevention element is configured to be transitioned in function of a liquid level rising from the one end to the other end
    Moreover, the sewer backflow prevention element may include any one or any combination of the preferred features described above as preferred features of the sewer backflow prevention element or the drain pipe connection device.
    The disclosure further relates to a diverter device for diverting a liquid from a drain pipe. The diverter device comprises a rainwater pipe connection device as well as a drain pipe connection device according to any one of the previously described, The rainwater pipe connection device comprises a rainwater inlet end for being connected to a rainwater pipe and a downstream end, A fluid such as rainwater can flow through the inside of the rainwater pipe connection device from the rainwater inlet end to the downstream end. Competitive, a fluid such as air / gas may also flow through the inside, e.g., in the opposite direction, in order to effect a pressure equalization.
    The diverter device may, for example, be used to divert rainwater so that rainwater is not led into the sewer system. A rainwater pipe (which may, for example, be mounted on or in a side wall building) is therefore connected to the rainwater pipe connection device at the rainwater inlet end. The drain pipe connection device is connected to a sewer pipe at the drain pipe connection end of the inner pipe piece of the drain pipe connection device.
    The diverter device is preferably used such that a part is located above the ground level and another part is located below the ground level. For example, the drain pipe connection device may be located partially or fully beneath ground / surface level.
    According to an embodiment, the downstream end of the rainwater pipe connection device is directly connected to the aeration connection end of the drain pipe connection device. This type of diverter device is especially compact and is especially advantageous for usage in situations where little space is available.
    According to an embodiment, the diverter device further comprises an outer extension pipe piece with a first end and a second end. The first end is connected to the downstream end of the rainwater pipe connection device. The second end is connected to the inlet end or the drain pipe connection device.
    According to some diver, the diverter device comprises a drain pipe connection device containing the inner pipe piece comprising an aeration connection end for being connected to a separate inner pipe piece with an aeration element, ie, not an inner pipe piece with an aeration end itself including an aeration element. For these, the diverter device preferably further comprises an inner extension pipe piece with a first end and a second end, the first end comprises an aeration end and an aeration element for reducing the pressure difference between inside and outside of the inner pipe piece. The second end is connected to the aeration connection end of the inner pipe piece or the drain pipe connection device.
    The aeration element of the inner extension pipe piece may have all of the preferable features described earlier on for an aeration element forming part of the inner pipe piece or the corresponding type of drain pipe connection device itself.
    The diverter device may, for example, consist of two separately produced components: the drain pipe connection device and the rainwater pipe connection device. Alternatively, the diverter device may consist of three separately produced components: the outer extension pipe piece, the rainwater pipe connection device, and the drain pipe connection device, or the inner extension pipe piece, the rainwater pipe connection device, and the drain pipe connection device. Alternatively, the diverter device may consist of four separately produced components: the outer extension pipe piece, the inner extension pipe piece, the rainwater pipe connection device, and the drain pipe connection device. However, the present disclosure also encompasses diverter devices consisting of or more than four separately produced components. In this paragraph, the term component is used to designate a one-piece product produced as a whole, i.e., without connection zones such as welding zones for holding together two separately produced pieces.
    Preferably, the aeration element comprises a covering element for preventing the liquid from entering the inner pipe piece. Reference is made for the explanations provided above for the aeration element forming part of respective described or the described drain pipe connection devices.
    Preferably, the rainwater pipe connection device comprises a pipe piece with a smaller diameter portion including the rainwater inlet end, a larger diameter portion including the downstream end, and a diameter transition portion. The diameter transition portion forms an intermediate region mediating between the smaller diameter portion and the larger diameter portion.
    The diameter of the outer pipe piece to be connected to the downstream end of the rainwater pipe connection device (either directly or via an outer extension pipe piece) may, hence, have a large diameter so that a sufficient amount of liquid (such as rainwater ) can be guided there-through while still keeping the inner pipe piece or the drain pipe connection device (and, if present, or the inner extension pipe piece) big enough to provide a sufficient volume or fluid passage, for example, for venting a sewer system.
    The diameter or the outlee end or the outer pipe piece pref erably lie 2S in a range or 85 mm to 165 mm, more vi '/' iS f Μ Χ..Λ * · X erably 105 mm to 145 mm, and fiZTrgt j n more preferably in a
    range or 115 mm to 135 mm. It is, hence, configured to be connected to a rainwater discharge pipe, for example, with a diameter of 125 mm.
    The diameter of the rainwater inlet and preferably lies in a range of 40 mm to 120 mm, more preferably 60 mm to 100 mm, and equally more preferably in a range or 70 mm to 90 mm. It is, hence, configured to be connected to a rainwater pipe, for example, with a diameter of 80 mm, Such a rainwater pipe may be attached to a side wall of a building and / or a part of a roof and / or a gable.
    The disclosure also relates to a method for producing a drain pipe connection device according to any of the previously described aspects. Likewise, the disclosure also relates to a method for producing a diverter device according to any one or the previously described exponent.
    Further, the disclosure also relates to the use of a diverter device according to any of the previously mentioned aspects to separate the rainwater drainage from a sewer system. In other words, the disclosure also relates to the use of a diverter device according to any one of the previously mentioned aspects for separating a rainwater drain pathway from a sewer system. Relying on the diverter device, rainwater can be efficiently diverted so that an overflow of the sewer system is prevented during periods of particularly heavy rain. For example, it is also avoided that sewer liquids, for example, containing faeces, flow out of rainwater pipes and pollute pavements and / or streets etc.
    Additional advantages and features of the. present disclosure, that can be realized on their own or in combination with one or several features discussed above, insofar as the features do not contradict each other, will become apparent from the following description of preferred exp.

    In the following description accompanying the various figures, like parts are denoted with like reference signs.
    FIG. 1 depicts an embodiment of a diverter device 1 according to the present disclosure. The diverter device 1 may, for example, be advantageously used for diverting rainwater from a drain pipe connected to the sewers.
    The diverter device 1 comprises a rainwater pipe connection device 20. Said rainwater pipe connection device 20 is configured to be connected to a rainwater pipe (not shown). The rainwater pipe may, eg ,, be attached, to a side wall of a building and / or a part of a roof etc.
    The rainwater pipe connection device 20 comprises a rainwater inlet end 21 to be connected to the rainwater pipe (not shown). Further, the rainwater pipe connection device 20 comprises a downstream end 22. The downstream end 22 is configured to be connected either directly or indirectly to a drain, pipe connection device. An indirect connection is, for example, established by interposing an outer extension pipe piece between the drain pipe connection device and the rainwater pipe connection device. In the case of the embodiment shown in FIG. 1, the downstream end 22 is connected to an outer extension pipe piece 30.
    The diverter device 1 further comprises a drain pipe connection device 10 according to the present disclosure. The drain pipe connection device 10 comprises an outer pipe piece 11 and an inner pipe piece 12. The outer pipe piece 11 is for transporting rainwater whereas the inner pipe piece 12 mainly serves the purposes of venting pipes belonging to the sewer system.
    The outer pipe piece 11 comprises an inlet end 13. The inlet end 13 is connected to the outer extension pipe piece 30 so that rainwater flows in from the inlet end 21 of the rainwater pipe connection device 20 can continuously flow through the rainwater pipe connection device 20, the outer extension pipe piece 30, and through the outer pipe piece 11.
    At its other end, the outer pipe piece 11 has an outlet end 14 configured to be connected to a rainwater discharge pipe (not shown). The rainwater discharge pipe may, for example, be a straight pipe which guides rainwater away from the installation place of the diverter device 1. This way, rainwater may, eg ,, be led to flow out into the open at a suitable distance such as fifteen or twenty meters (or any other convenient distance) away from the respective building with a rainwater pipe and connected to the sewer system.
    Partially located inside of the outer pipe piece 11 is an inner pipe piece 12. The inner pipe piece 12 is straight in the case of this edition and penetrates a pipe wall 15 of the outer pipe piece II at a penetration zone P.
    The inner pipe piece 12 comprises a drain pipe connection end
    16 for being connected to a drain pipe (not shown) communicating with the sewer system (not shown),
    Further, the inner pipe piece 12 comprises an aeration connection end 17 for being connected to a. Separate inner pipe piece 40 with an aeration element 50.
    As shown in FIG. 1, there is an angle between the outlet end 14 of the outer pipe piece 11 and the drain pipe connection end 16 of the inner pipe piece 12. This ensures that a rainwater discharge pipe (not shown) and a pipe (not shown) establishing a connection to the sewers can be easily and conveniently connected, and that rainwater can be diverted at an angle with respect to the drain pipe leading to the sewers.
    The angle a in FIG. 1 amounts to 90 °. However, the present, disclosure and encompasses vary the angle takes on any other value different from 0 °, preferably, the angle in a range or 45 ° to 135 °. An angle of less or more than 90 ° may be especially useful when using the diverter device 1 in a location on the surface ground is inclined, for example, when the diverter device is installed at a house located on a hill. However, for most applications, an angle close to .90 ° is especially preferable.
