    one
    The invention relates to pump construction, relates to hydraulically driven pumps, and may find application in the technique for pumping various fluids.
    The aim of the invention is to increase the speed of the pump by reducing the mass of moving parts.
    The invention is illustrated in the drawings.
    Figure 1 shows the constructive scheme of the pump; FIG. 2 is a view A of FIG. 1; in FIG. 3 a membrane assembly with a stem and a rigid center; on. Fig, 4 - view, hard center; FIG. 5 shows a rigid center assembly assembled with a rod.
    ,
    The pump includes a housing 1, a two-layer diaphragm 2, fixed on. the periphery in the housing 1 with the formation of the discharge 3 and the working 4 chambers, respectively, and having a solid front layer 5 facing the discharge chamber 3, and the back layer 6 facing the working chamber 4, the pump also has channels 7 and 8 for supplying and discharging the pumped media communicated with the injection chamber 3, channel Y for supplying and discharging the drive medium communicated with the working chamber 4, the rigid rod 10 of the engine passing through the central guide hole 11 with the seal 12 in the wall 13. to the housing 1 on the working side 4 cameras, stock 10 have t on the outgoing end of the support plate 14 for the spring stop 15 placed between the housing 1 and the support plate 14 concentric to the rod 10, and at the opposite end - the head 16. and the perforated rigid center 17, molded to the diaphragm 2 Made perforated with offset perforations 1-8 relative to the perforations 19 of the hard center 17, the continuous front layer 5 of the diaphragm 2 has a concave central part 20 covering the head 16 of the rod 10. The housing 1 is provided with supporting protrusions made on the inner surface and the working chamber 4 facing. to the back layer 6 of the diaphragm 2, the pump is equipped with a discharge valve installed in the channel 8 and a suction valve installed in the channel 7,
    The pump works as follows

    51352
    At. the flow of the drive medium through channel 9 into the working chamber 4 aperture
    2 moves to discharge, forces the pumped medium out of the chamber
    3k to the consumer through the discharge valve and squeezing the spring through the brush 15, After shutting off the drive medium supply, the diaphragm 2 returns
    (O (back by the action of the spring 15, suction the pumped medium into the chamber 3 through the suction valve. At the end of the stroke, the diaphragm 2 sits on the protrusions that provide
    15 is the initial clearance for the passage of the drive medium under the diaphragm. Perforations on the back layer 6 of the diaphragm 2 allow for its formation with a hard center.
    20 17 install the latter on the technological supports included in the perforations 18, and thereby strictly fix it. In this case, it is possible to reduce. sew the thickness of the molded diaphragm layer, and hence its mass, which increases the speed of the pump.
