    A machine of the axial piston pump type used as a pump or motor including a cylinder drum mounted rotatably in a casing. Working pistons are included in the drum in working cylinders and driven as the drum rotates. The casing terminates in a tubular duct coaxial therewith that defines one of the suction and pressure openings of the machine. The tubular duct is of a diameter generally the same as that of the drum to provide for the direct flow of fluid medium to the working cylinders without undergoing a change in the direction of flow. The tubular duct terminates in a first connecting flange, and a second duct defines the other of the suction and pressure openings and terminates in a second connecting flange that extends to the side of the tubular duct.

    1 The invention relates to mechanical engineering and can be used where it is required to transport to viscous masses.
    Known axial-piston hydraulic machine with a rotating cylinder block installed in the housing, and a distribution device, discharge and suction nozzles, in the latter of which the impeller is fl}
    A disadvantage of the known pump is the narrow cross-section of the suction inlet. This pump cannot be flanged to the reservoir of the medium being pumped, which limits the scope of application. So. for example, it is not possible to transport a coarse-grained or viscous medium with sufficient efficiency and productivity.
    The purpose of the invention is to increase efficiency and productivity.
    This goal is achieved by the fact that the suction nozzle is made with a diameter equal to or greater than the diameter of the cylinder block, and the discharge is installed perpendicular to the suction, having a flange for direct connection of the latter.

    FIG. 1 shows the proposed hydraulic machine, a longitudinal section;
    ya fig. 2 is a view A of FIG. 1 with a sny wheel.
    Hydraulic machine contains rotates 11is cylinder block 1, mounted
    in the housing 2 by means of bearings 3 and 4. In block 1 of the cylinders, rods 5 are mounted, which move reciprocally in the axial direction. With rods 5 are connected
    pistons 6, which are made depending on the medium used. The switchgear 7 has a discharge nozzle 8 and a suction nozzle 9 in which a impeller 10 is mounted fixed on the shaft 11 with a screw 12 and a cap 13. The suction nozzle 9 is made with a diameter equal to or greater than the diameter of the cylinder block 1,
    and the discharge nozzle 8 is installed perpendicularly to the suction 9, having a flange 14 for direct connection with the resetauar of the transported medium (in the drawing
    not shown). 5 stocks have balls 15,

    Claim
    Axial-piston hydraulic machine : with a rotating cylinder block mounted in the housing and a switchgear having a discharge and suction nozzles, a pistol has been installed and the last of which is the impeller, due to the fact that Efficiency and performance, the suction pipe is made with a diameter equal to or greater than the diameter of the cylinder block, and the discharge is installed perpendicular to the suction pipe having a flange for direct connection of the latter with
    10 reservoir of the transported medium.
