Hydrostatic axial piston motor of bent-axis construction

A variable-displacement hydrostatic axial piston motor of bent-axis construction, comprising:

• a drive shaft;
• a cylinder drum configured to be pivoted in a pivoting plane;
• a one-piece port plate, which has a central plane extending parallel to the pivoting plane, and on which there are two working ports with flat port surfaces, of the two working ports, one working port is situated on one side of the central plane and the other working port is situated at the same distance from the central plane on the other side of the central plane;
• an adjusting device including an adjusting piston arranged in a cylindrical receiving space of the port plate;
• a control valve arranged on a first side of the port plate and having a control valve piston,
• a feedback spring arranged in the port plate and clamped between the adjusting piston and the control valve piston, the feedback spring arranged together with the adjusting piston and the control valve piston on one axis;
• a counterbalance valve having a counterbalance spool;
• and
• two secondary pressure-limiting valves inserted as cartridge-type inserts into the port plate, one of the secondary pressure-limiting valves is arranged on one side of the central plane and the other of the secondary pressure-limiting valves is arranged on the other side,
• wherein the counterbalance spool is accommodated in a valve bore in the port plate, the valve bore extending perpendicular to the central plane,
• wherein the two working ports are situated on an opposite side of the port plate as the first side, and the flat port surfaces are configured as two mutually spaced port surfaces, and
• wherein the two secondary pressure-limiting valves are (i) arranged on the same side of a third plane as the flat port surfaces, the third plane passing through the axis of the valve bore for the counterbalance spool and extending perpendicular to the axis of the adjusting device and (ii) arranged between the two flat port surfaces.
