Abstract

See full text

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.
