摘要： An axial piston machine of oblique axis design has a pivot angle that is adjustable via a set piston and a control valve and includes a first valve slide that is linearly movable relative to a first valve axis and is connected at two opposite ends to a first or a second fluid port. The first valve slide has a central region that defines a control point at which the lower of pressures at the first and second fluid ports act. The control point is connected via a fixed first throttle and a second throttle to a housing interior. A second valve slide that is linearly movable relative to a second valve axis is configured to adjust the second throttle. The first valve axis is arranged between the set piston and the control valve or a region of the control valve and is oriented transverse to the adjusting axis.

摘要： A control plate, for alternatingly fluidically connecting hydrostatic operating chambers, in particular of an oblique axis type axial piston machine, with pressure medium connections, includes a first end face, a second end face, at least a first recess, a first kidney-like control opening, and at least one through-recess. The first face extends transversely to a rotation axis. The second face faces away from the first face. The first recess is bounded in the first end face by the first control opening, and at least partially forms the at least one through recess, which extends toward the second end face from the first end face at an end portion of the first control opening, and which is arranged in or counter to a rotation direction of the rotation axis. An oblique axis construction type axial piston machine includes such a control plate.

摘要： A variable-displacement hydrostatic axial piston motor of bent-axis construction includes a drive shaft, a cylinder drum that pivots in a pivoting plane, and a one-piece port plate nearly symmetrical with a central plane and with two working ports. The motor further includes an adjusting device with an adjusting piston arranged in the port plate, a control valve arranged on the port plate and with a control valve piston, a feedback spring arranged in the port plate and clamped between the adjusting piston and the control valve piston, a counterbalance valve with a counterbalance spool, and two secondary pressure-limiting valves inserted as cartridge-type inserts into the port plate. The counterbalance spool is accommodated in a valve bore in the port plate. The two working ports are situated on the port plate opposite to the first side. The two secondary pressure-limiting valves are arranged on the same side as the port surfaces.

摘要： A hydrostatic axial piston machine includes a drive shaft and a plurality of cylinder sleeves in which a spherical or ball-shaped section and a spherical or ball-shaped piston are inserted to delimit a respective displacer chamber. The sections are secured on a rotor, while the pistons are secured on a piston disk or piston drum. The piston disk is configured to be tilted at different pivoting angles relative to the rotor in a variable-displacement machine, or the piston disk is tilted continuously relative to the rotor in a constant-displacement machine. The rotor and the piston disk are coupled to one another for conjoint rotation by a driving device. The rotor and the piston disk can also be coupled indirectly by a drive shaft of the machine. A sliding joint axial with respect to a drive shaft is arranged between the rotor and the piston disk.
