    [0001] The present invention relates to an electromagnetic valve for a reservoir valve of a fuel supply installation for supplying a gaseous fuel to a storage container and for supplying a consumer with gaseous fuel from that storage container. The present invention further relates to such a reservoir valve and a fuel supply installation with such an electromagnetic valve.
    [0002] Alternative gaseous energy carriers, such as natural gas, methane, biogas and hydrogen, have been growing in importance in transport due to their CO2 saving potential and for reasons of supply security. These energy carriers, to obtain the required coverage, are typically stored in compressed form in pressurized cylinders at nominal pressures of up to 70 MPa (700 bar) and made available to the consumer at an operating pressure of about 1 MPa (10 bar).
    [0003] The electromagnetic valve controls the flow of gas when filling and operating the mark and is an essential integral part of a reservoir valve, which contains additional safety elements, such as, for example, safety against overpressure and/ or thermal safety for safety of the storage container against inadmissibly high pressures or fire action, flow limiters for protection against inadmissibly high gas streams after rupture of an external component, control elements such as, for example, manual shut-off valve for prevent gas flow, service valve for manual emptying of the storage container, additional elements such as, for example, filter element to protect the control elements against contamination, check valve for pressure maintenance, temperature sensor for measuring the gas temperature in the reservoir, and the like, and satisfies high safety requirements with that of outer strength.
    [0004] The technician knows different ways of executing electromagnetic valves, whose operation and arrangement determine the shape and size of the reservoir valve.
    [0005] From US 5 188 017 is known a pre-controlled electromagnetic valve, to be disposed externally, with an armature in one piece. The advantages are the simple structure of the electromagnetic valve and the simple drilling template of the reservoir valve. The disadvantages are the construction size of the electromagnetic valve and the reservoir valve due to the size of the magnetic coil, the power take-off of the electromagnetic valve by the armature in one piece, lack of protection against external force action and against improper handling and the less storage volume of the reservoir due to the large mounting height of the reservoir valve.
    [0006] From DE 601 02 241 a reservoir valve with a pre-controlled electromagnetic valve to be internally arranged with an armature in one piece is known. The advantages are the protection against external force action and against improper handling and the simple drilling template of the reservoir valve. Disadvantages are the technical feature of assembly due to the number of components of the electromagnetic valve and the power take-off of the electromagnetic valve by the armature in one piece.
    [0007] From DE 103 61 781 a reservoir valve with a pre-controlled electromagnetic valve to be arranged internally with a movable pole is known. The advantages are protection against external force action and the power take-off of the electromagnetic valve by the mobile opposite pole. The disadvantages are the technical assembly feature for the electromagnetic valve due to the number of components, the technical assembly feature and the assembly size of the reservoir valve due to the transverse perforations required to be closed by the externally accessible longitudinal assembly and the absence of protection against manipulation improper.
    [0008] The present invention aims to avoid the disadvantages of the current state of the art and provide an electromagnetic valve or a reservoir valve in a compact and simple construction mode, which presents, among others, some or all of the following advantages: - construction form compact and small electromagnetic valve power take-off by selected operating principle; - simple structure of the electromagnetic valve due to a small number of components; - protection against external force action and against improper handling by disposing of the electromagnetic valve inside the storage container; - Compact design of the reservoir valve with simple drilling template by placing the electromagnetic valve inside the storage container.
    [0009] The electromagnetic valve according to the invention for a reservoir valve of a fuel supply installation of a gas motor vehicle comprises a magnetic coil with a return and a magnetic armature, which is axially movable in the interior return. The magnetic armature consists of an armature, a sealing element, which is placed between the armature and a fuel supply, and an opposite pole, which rests against the sealing element.
    [00010] The magnetic coil preferably comprises a fastening component, the inner return, an outer return and a lock. The electromagnetic valve preferably further comprises an elastic element, which with an unexcited magnetic coil compresses the armature against the sealing element and the sealing element against the sealing area.
    [00011] In other words, the objective is achieved, for example, by a pre-controlled electromagnetic valve, without housing, with a mobile opposite pole, whose displaceable magnetic armature consists only of a sealing element, which is guided by the internal return of the coil magnetic, with the opposite pole touching the sealing element and, for the armature, which is covered at least partially by the sealing element, it forms the first operational slot for opening the pilot hole by lifting the armature from the pilot sealing area, and the opposite pole forms in axial direction towards the inner return the second operating slot for opening the feed by lifting the sealing element from the main sealing area.
    [00012] By the execution with mobile counter pole, the pilot course for opening the pilot hole is independent from the main course for opening the pilot hole, so that with the first small operational slot for opening the pilot hole, a small electrical power and with the second large operating slot a large flow cross section is obtained with little throttling losses. By direct conduction of the magnetic armature in the inner return of the magnetic coil, which conducts the magnetic field specifically to the and of the magnetic armature, the power take-off of the electromagnetic valve is further reduced. Obstruction of the electromagnetic valve in the high-pressure compartment of the storage container does not require a pressurized housing, which facilitates the diffusion of the magnetic field, and, despite this, protection is ensured with the action of external force and against improper handling. By simply assembling the three-part magnetic armature (arm, sealing element, opposite pole) and the dispensed pressurized housing, the electromagnetic valve's weight and costs are reduced.
    [00013] The magnetic coil and the magnetic armature are preferably arranged in such a way that, when activating the magnetic coil, initially a pilot opening for the fuel is produced by displacement of the armature towards the opposite pole and by detachment of the armature from the sealing element, and then a main fuel opening is produced by moving the magnetic armature towards a magnetic coil closure and detaching the sealing element from the fuel supply.
    [00014] The first operational slit is preferably smaller than the second operative slit, so that the first operational slit matters for example between 50 and 0.5% and still preferably between 25 and 0.01% of the length of the second operating slot. The pilot opening preferably has a flow cross section smaller than the main opening, which is preferably between 25 and 0.05% and more preferably between 15 and 1% of the flow cross section of the main opening.
    [00015] The present invention further relates to this reservoir valve and a fuel supply installation with this electromagnetic valve. The present invention further relates to a throughflow limiter for a valve body fuel supply installation with an integrated filter element.

    [00027] As shown in Fig. 1, a fuel supply installation 100, especially of a gas operated motor vehicle, fueled by fuel gas, for supplying a consumer 101 with gaseous fuel such as natural gas, methane, biogas, hydrogen or the like, comprises one or more storage tanks 102 with tank valve 103 and electromagnetic valve 200, which when filling are supplied with fuel gas by a filling coupling 104 arranged on the filling side with integrated backflow lock and filter and a gas supply conduit 105 connected thereto, and the consumer 101 by a regulation unit 106, consisting of at least one pressure regulator, which reduces the pressure of the stored gas from storage pressure to operating pressure.
    [00028] As shown in Fig. 2, the electromagnetic valve 200 comprises in a preferred embodiment a magnetic armature 201 in several parts, a magnetic coil 202 in several parts and, preferably, a spring as an elastic element 203 for closing or release feed 208c against high pressure compartment 102a of storage container 102. Magnetic armature 201 comprises a sealing member 204 of a suitable sealing material with a main sealing area 204a for sealing against sealing area 208d of the attachment of valve 208, a pilot seal area 204b for sealing against the associated pilot seal area 205a of armature 205, and a perforation 204c between pilot seal area 204b and main seal area 204a and a support 204d for counter pole support 206 in the sealing member 204, a magnetizable armature 205 with a pilot seal area 205a for sealing against the associated pilot seal area 204b and grooves. 205b for housing the support 204, a magnetizable, movable counter pole 206 abutting on the support 204d, with an internal perforation 206a for housing the elastic element 203. Elastic element 203 compresses armature 205 against sealing element 204 and sealing element 204 against sealing area 208d and, in the non-current state, with unexcited magnetic coil 208d, seals the flow path between supply 208c and high pressure compartment 102a of storage container 102. Between armature 205 and counter pole 206 is located the first operating slot 205c and between counter pole 206 and closure 210 is the second operational slot 206b of the magnetic system. The magnetic coil 202 comprises a multi-part interior return 207 of a magnetizable valve attachment 208 with attachment threads 208a suitable for attaching the electromagnetic valve 200 to the reservoir valve housing 103, a groove 208b for housing a suitable seal for sealing of high pressure compartment 102a for supply 208c, a sealing area 208d for sealing against associated main sealing area 204a and flow paths 208e for high pressure compartment 102a of storage container 102, a non-magnetic spacer piece 209 for conducting the magnetic field and a magnetizable closure 210. The magnetic coil 202 further comprises a magnetic winding 211 covered by extrusion of a coil body 212 for housing a winding (copper wire) and a magnetizable outer return 214 for joining the individual parts of the magnetic coil 202 and the valve 200 electromagnetic.
    [00029] As shown in Fig. 2, in the de-energized and unexcited state of the magnetic coil 202, the elastic element 203 compresses by armature 205 the pilot seal area 205a against the associated pilot seal area 204b and the main seal area 204a against sealing area 208d and thus closes the joint between high pressure compartment 102a of storage container 102 and feed 208c. In this operational state, between armature 205 and opposite pole 206 there is a first operational slot 205c.
    [00030] As shown in Fig. 2.1, at the beginning of the withdrawal by activation with current of the magnetic coil 202 a magnetic field is established by the magnetizable parts of the magnetic armature 201, the operating slot 205c, the magnetizable parts of the interior return 207 and the return 214 outside of the magnetic coil 202. Due to the magnetic force in the operating slot 205c the armature 205 is pulled against the force of the elastic member 203 towards the counter pole 206, which bears on the sealing member 204, and lifts the pilot sealing area 205a of the associated pilot seal area 204b. High pressure gas from the counter pole region 206 may flow into the feed until pressure compensation through the pilot port 204c is released into the feed 208c.
    [00031] As shown in Fig. 2.2, due to the flow of gas at high pressure from the region of the counter pole 206 through the pilot hole 204c, a pressure difference results, which compresses the magnetic armature 201 against the spring force of the elastic element 203 against the closure 210 and lifts the main sealing area 204a from the associated sealing area 208d and releases the flow path from the high pressure compartment 102a of the storage container 102 to the feed 208c.
    [00032] By turning off the current, the magnetic field in the electromagnetic valve 200 is undone and the elastic element 203 moves the armature 205 with the sealing element 204 to the closed position as shown in Fig. 3, and is dragged in reverse to the closed position by the magnetic forces still present. The closing effect is reinforced with perforation 204c closed by the pressure difference established by the magnetic armature 201.

Between the sealing member 601 and the counter pole 606 the first operative slot 602c and the drag slot 606d are formed and between the counter pole 606 and the closure 210 the second slot is formed. operational 206b.
    [00037] By the forced drag command 601b and 606b the sealing element 601, in addition to the compressive forces on the individual parts of the armature 600, is lifted by the existing magnetic force of the associated sealing area 208c.
