    Die Maschine enthält stemförmig angeordnete Zylinder (1), die unter Zwischenschaltung von Ventilpatronen (8 und 9) an ein Formstück (12) angeschlossen sind. Dieses Formstück (12) besteht aus zwei Sätzen von Rohren (17 und 18), die sternförmig angeordnet sind. In einem der Sätze von Rohren (17) sind die Saugkanäle (13) der Maschine ausgeführt. Im anderen der Rohrsätze (18) sind die Druckkanäle (14) ausgeführt. Die mittigen Enden der Saugkannäle (13) münden in einen sich in der Mitte des Formstückes (12) befindlichen Hohlraum (15), der mit einer Schraubenhülse (16) zum Anschluss einer Saugleitung versehen ist. Die mittigen Enden der Druckkanäle (14) sind untereinander strömungsmässig verbunden, wobei einer der Druckkanäle (14) mit einer Austritsöffnung (23) für das Fluid versehen ist. Die Verwendung des genannten Formstückes vereinfacht wesentlich die Verbindung der einzelnen Teile der Maschine untereindander und mit den an die Maschine angeschlossenen Leitungen.

    The invention relates to hydraulic machine building, in particular, to piston machines with valve distribution.
    The purpose of the invention is to simplify the connection of pipelines and increase reliability.
    FIG. 1 shows a piston of a machine from the side of a connecting piece common to all cylinder heads; in fig. 2 is a section A-A in FIG. 1j in FIG. 3 - the point of connection of the common connecting piece to the cylinder head, option; 4 shows a piston machine from the side of the joint part common to all cylinder heads, an option.
    The piston machine contains at least two radially arranged cylinders 1 with pistons 2 mounted with the engagement of an eccentric 3 located on the shaft 4 of the electric motor 5. Each cylinder 1 has a head 6 with flanges 7 for connecting an intake valve 8 and a discharge valve 9 having flat docking surfaces. The cavity where the eccentric is located
    3, gripping the lid 10 with the oil-filled holes 11.
    All valves 8 and 9 ns jats to the flanges 7 of heads 6 with the help ofiiueii for all heads of the connecting piece 12, in which radially directed suction 13 3 directed to each head 6 in the radial direction are connected to form separate suction and injection collectors. Each; and a pair of suction 13 and injection 14 channels, and 1 directed to one cylinder 6 of cylinder 1, are angled to one another, as shown in FIG. 1. The ends of the suction channels 13 exit into a cavity 15 provided in the part 12 with a portion of the threaded surface 16 for connection to an external pipeline.
    The overall connective parts 12 can in principle be made in the form of a plate in which the said channels 13 and 14 are made, but instead of the plate it is possible to interconnect the pipes 17 and 18 in such a way that the suction channels 13 pass through the pipes 17 and discharge 14, pr this cavity 15 is separated from the injection

    The internal connections 12 in the area of the corresponding head 6 have tides in the form of flanges 20 with holes 21 for the passage of screws (not shown), which are screwed into the corresponding threaded holes in each head 6 Pi1P1 1. One of the downstream discharge channels 14 has a socket for connecting an external injection pipe, made in the form of an outlet 22 in the wall of a common fitting 12, in the area of the outlet 22 a common connector on the part 12 can have a flood 23 with threaded holes 24 for fastening} 1 and the external discharge pipeline, tide 23 can also cover tube 17, in which case a hole 25 can be made in it, connected) first with suction duct 13, which allows to install on tide 23 a bypass device (not shown), for example a safety valve.
    ; The piston machine c} 1 is attached to the connecting tube 26 connected to the suction channel 13 in the pipe 17 of the common connecting part 12 and with the internal cavity of the cylinder 1 in the area of the piston 2 seal, for which an intermediate part 27, located by the cylinder 1 and the head 6, is annular groove 28. Tube 26 is sealed with relative, but common connecting piece 12 with a seal 29.
    Seal}) the piston 2 is made in the form located on the two sides of the collar) Nev grooves 28 pairs of cuffs 30,
    31 and 32, 33. Cuffs 30 and 31 are installed between the intermediate piece 27
    and head 6 cylinder 1, and cuff
    32 and 33 - between the intermediate piece 27 and the stop ring 34, sandwiched between the intermediate piece
    27 and the end of cylinder 1, as shown} ia of FIG. 3
    The piston machine is equipped with a device for feeding into the suction channel 13 mixed foreign material, such as chemical or detergent in the back part} Fifth ratio with the volume of the pumped medium. This device is made in the form of a tube 35, one end 36 of which enters the suction channel 13 of the common connect. 1 of the body part 12 and is located coaxially with the inlet to the suction valve 8 of the head 6 of the cylinder 1, while the second end of the tube 35 is connected to a container with a blended material (not shown).
    Piston machine works as follows.
    When the shaft 4 is rotated by the electric motor 5, the eccentric 3 causes the pistons 2 to reciprocate, which provides a periodic increase and decrease in the volume of working chambers in the heads 6 of cylinders 1. When the volume of the working chamber in the head 6 increases, the pumped medium through the suction valve 8 from the suction channel 13 enters the working chamber; a suction stroke occurs. When the volume of the working chamber in the head 6 is reduced, the pumped medium from it through the discharge valve 9 is forced out by the piston 2 into the corresponding discharge channel 14, from where it goes to the consumer through the outlet 22. When the seal is worn. the piston 2, for example the cuff 30 and 31, the leaks of the pumped medium from the working chamber of the head 6 enter the annular groove 28, where due to the vacuum in the suction channel 13 through the connecting tube 26 are removed into the suction channel 13, at the same time the cuff 32 and 33 prevent the penetration of the medium into the cavity where the eccentric 3 is located, and provide protection against penetration of lubricating fluid from this cavity into the working chamber of the head 6 of the cylinder 1.
    If it is necessary to mix foreign matter into the pumped medium, the tube 35 is connected as indicated to the container with the material to be mixed. With this connection, the end 36 of the tube 35 in the suction channel 13 reduces the cross section of the latter, with the result that a pressure drop is formed in the zone of the end 36 of the tube 35, which ensures the flow of the mixed material from the container with the mixed material into the pumped medium.
