It is characterized by separating all of them.
    Thus, what was previously required for two different separation processes is carried out by one process according to the invention.
    Moreover, since gas meta is an article produced in large quantities, the simplification of the manufacturing method has the advantage of reducing the manufacturing cost.
    In an embodiment of the invention, all of the connecting passages of the gas meta are opened to one side of the central body, and the separating direction is perpendicular to the side of the central body.
    As a result, in the present invention, as in the prior art, a process of fixing an additional sealing member (plug) to one part of the connection passages performed by separation in a direction different from that in which all other passages except the connection passages are separated is provided. It is not necessary.
    The manufacturing method of the present invention is thus simplified, so that its economic cost is reduced.
    The invention also includes a plurality of deformable diaphragm measuring chambers and a central body in which a plurality of passages are formed, the passages of the central body supplying gas to and from each of the central bodies from outside of the central body and from the central body. It is to be discharged, and all the connecting passages are of a type of gas meta open to one side of the central body, each passage is characterized in that it is fully visible from one side of the central body.
    The gas meta manufactured as described above is simplified and more reliable than the gas meta of the prior art because the risk of gas leakage due to improper fixing of the sealing plug is prevented.
    More specifically, the dispensing cover comprises four ports separated from each other by radial sealing strips, each in the form of a quadrant, each of the four connecting passages connecting the measuring chambers. Radial trips to communicate with the open end without being blocked by the cover of each connecting passage, the circular ring forming four openings all in communication with the open end of the fifth passage for outgassing; To cooperate.
    Moreover, the cover has a radial direction in which a portion is disposed between the two openings to close the open end of the fifth passageway for sealing between the connecting passageways and the fifth passageway in which the two openings and the open ends communicate. A member extending on either side of one of the strips.
    Preferably, the fifth connecting passage is arranged between two adjacent connecting passages, one end of which is disposed in the center and the other four connecting passages are arranged around it.
    Other features and advantages of the present invention will become more apparent from the following description provided without limitation with reference to the accompanying drawings.
    As shown in FIGS. 5 and 6, the gas meta of the present invention, denoted entirely by reference numeral 38, firstly comprises a central block 40 and two covers, only one of which covers 42. 6 is shown.
    Two chambers are formed in the central block 40, of which only one chamber 44 is shown in FIG. 5. Each chamber is first defined by a central block 40 and secondly by a deformable diaphragm (diaphragm 46 of FIG. 6). The covers are mounted to the central block 40 and cooperate with respective deformable diaphragms forming an additional measuring chamber. Two chambers are arranged on either side of each deformable chamber and the volume of the chambers varies with the position of the diaphragms.
    As shown in FIG. 5, the central block 40 has four passages 48, 50, 52, and 54 formed therein, and each passage is in communication with the corresponding measurement chamber. For example, the passage 48 is in communication with the measurement chamber 44 and the passage 50 is in communication with the measurement chamber (not shown in FIG. 5) which is symmetrical to the measurement chamber 44 about the central block 40.
    The passages 44-54 are distributed around the central portion.
    The enrichment block 40 is also formed with a fifth connecting passage 56 which allows gas to be discharged therefrom.
    A passage 58 is disposed between two adjacent passages 52, 54 and extends radially from one of the ends 56a to form a central portion and an opposite end disposed on the outer circumferential side of the central block 40. Facing 56b.
    All five connecting passages have one end open at the common upper surface 58 of the central body.
    As shown in FIG. 5, each passageway is free of any obstructions that may block a portion of the passageway from the common top surface 58 and thus can be seen from the top surface 58.
    As shown in FIG. 7, the upper surface 58 of the gas meta has a planar metal plate member 60 which is stacked to prevent gas leakage and is fixed to block the open ends of the connection passages 48 and 56. Accept.
    A hole penetrating the metal plate member which is centered and fixed to the end portion 56a of the fifth passage 56 formed together with the center portion is formed.
    The diameter of the hole is larger than the diameter of the end of the fifth passage so that a portion of the open end of each of the four other connecting passages 48-54 is left uncovered.
    The circular portion 62, known as the "distribution cover", is mounted to the plate member 60 of metal on the hole.
    The cover 62 has four openings 64, 66, 68, 70, each of which is in the form of a quadrant and is separated from each other by radial sealing strips 64a-64d.
    Each of the openings is in communication with the unopened open end of each of the four connection passages 48-54.
    In the circular ring 64e at the center of the dispensing cover 62, four small holes 72-78 are located directly above the end 56a of the fifth passage 56 with radial strips 64a-64d. Are formed, and the fifth passage communicates with the respective holes so as to coincide with the central portion.
    As shown in FIG. 5, the cylindrical support 80 of the shaft perpendicular to the upper surface 58 of the gas meta is disposed inside the end 56a of the fifth connecting passage and fixed to the central block 40.
    In the center of the cover 62 a pivot 82 is mounted on the central axis of the support 80 to receive a gas distribution element 84 referred to as a "distributor" as shown in FIGS. 8 and 9.
    The dispenser 84 is mounted to rotate on the surface of the dispensing cover 62 and has four circularly divided sectors, which are arranged to form holes 84a and blocking 84b, The blocking portion is separated by two planar portions 84c and 84d each making an angle of 90 degrees.
    The dispenser 84 also has a hollow central portion 84e, which includes a bearing 84f that engages the pivot 82 and is in communication with the hollow blocking portion.
    The hole 84a defined by the distributor acts to place each of the openings 64-70, thereby allowing each of the four connecting passages 48-54 to communicate with the outside of the central body 40 so that the gas is in the corresponding measuring chamber. To get into.
    The dispensing portion 84b and the central portion 84e of the distributor allow one of the four passages 48-54 to communicate with the fifth passage 56 through the aperture of the dispensing cover and the corresponding opening. Isolate the assembly from the outside of the body and the two planar portions 84c and 84d remain closed with the remaining openings.
    Thus, the gas present in one of the measuring chambers leaves the chamber along the corresponding connection passage, through the corresponding opening, and then into the interruption 84d and the central portion 84e of the distributor, followed by the opening 72 of the cover. Flows through the fifth connecting passage 56 through -78 and penetrates through the plate member 60 of metal and exits from the measuring chamber through a hole 86 that coincides with the opposite end 56b of the passage. .
    The member 87 thus closes each of the open ends to seal between the fifth passageway and the connecting passages 52, 54 and the open ends of the upper surface 58 communicate with the openings 68, 70. .
    As is well known, the rotation of the distributor controls the ingress and discharge of gas from and into the various measuring chambers. Gas meta with four chambers and a rotary distributor is well known, for example known from US Pat. No. 3,161,049. Therefore, it would not be necessary to describe in detail the relationship between the position of the diaphragms of the measuring chambers and the rotary distributor operation for such a gas meta. It will be sufficient to refer to the above-mentioned patent publication.
    Nevertheless, it should be mentioned that the gas meta has power transmission means for kinetically connecting the distributor to the deformable diaphragm.
    As shown in FIGS. 5 and 7, the power transmission means comprise two fins 88, 90, the fins of which penetrate a central block 40 at a portion of the height and communicate with the measuring chambers of the gas meter. do. In FIG. 7, a portion of the fin 88 can be seen in the chamber 44. Each of these pins is connected to a deformable diaphragm and performs a rotational movement in response to the displacement of the diaphragm.
    The power transmission means also includes two sets of levers (not shown in the figures) connecting one of the pins 88, 90 to the other pin that engages the hole 92 formed in the dispenser 84. The movement of the deformable diaphragm while the gas enters or exits the measuring chamber is transmitted by the power transmission means to a distributor 84 which is correspondingly rotated.
    The central body 40 of the gas meta is made using a technique of injecting molten aluminum into a metal mold made up of a plurality of mold members at a pressure driven by the piston (for example 1000 bar).
    After sufficient time has elapsed for the aluminum to solidify, the various mold members are removed by separation, as shown in FIG. 10, and the members 94, 96, 98, 100 and 102 acting to form connecting passages 48 and 56 are formed. Removed.
    The mold members 94-102 are removed in a single operation in the direction of the arrow marked D, which is perpendicular to the top surface 58 of the central body 40 (FIG. 10).
    Such separation is particularly convenient.
    However, the mold members 94-102 may be composed of one member.
    Each mold member 94-102 is artificially connected to the corresponding connecting passage 48-56 by a showing line in the central block 40.
    FIG. 11 is a schematic cross-sectional view in plan view perpendicular to the top surface 58 of the central block 40, which houses the support 80, showing the mold member 102 from the fifth connecting passage 56.
    This figure shows the simplification provided by the present invention as compared to the prior art in which two separation directions are needed and subsequently the seal plug 36 must be installed as shown in FIGS. 3 and 4.
