    Abstract: On a near-bottom inner surface of a tilt piston cylinder hole, only a limited part that contacts an end of a tilt piston when the tilt piston is tilted by a pressing force from a swash plate is laser-hardened along the circumferential direction of the tilt piston cylinder hole (i.e., a hardened part is formed). In the tilt piston cylinder hole, parts other than a near-opening inner surface and the near-bottom inner surface are not laser-hardened.

    Abstract: An axial piston machine may include a rotor with a shaft. A plurality of cylinders may be arranged in an annular manner about the shaft. A plurality of pistons may each be positioned within each of the plurality of cylinders and may be constructed and arranged to move translationally within the plurality of cylinders. A cylinder head may include a plurality of inlet openings and may be in operative communication with the plurality of cylinders. A sealing washer having a plurality of passage openings may be disposed on the cylinder head so that the plurality of passage openings and the plurality of inlet openings may be flush with one another. A number of the plurality of inlet openings may correspond to a number of the plurality of passage openings. A valve plate may be connected to the shaft in a rotationally fixed manner and may be constructed and arranged to be brought into congruence with the plurality of passage openings of the sealing washer based on a rotary angle. The sealing washer may be disposed between the plurality of inlet openings and the valve plate and may be prestressed against the cylinder head and onto the inlet openings.

    Abstract: An axial hydraulic pump-motor, in which a cylinder block having a plurality of cylinder bores on a valve plate having a high-pressure side port and a low-pressure side port for controlling an amount of reciprocation of a piston in each of the cylinder bores, the hydraulic pump-motor includes: a residual pressure release port provided on the valve plate and communicating until the cylinder bore on a top dead center side communicates with the low-pressure side port; a residual pressure acquisition portion obtaining a value of a residual pressure in the cylinder bore on the top dead center side; and a directional switching valve switching a flow path between the residual pressure release port and an hydraulic oil tank and a flow path between the residual pressure release port and the low-pressure side port.
