Hydrostatic double axial piston pump

摘要

The hydrostatic double axial piston pump has the mainshaft (5) which serves as a common driveshaft for the first drive set (3) and a filling pump (13), as well as a gearing stage for the adjacent shaft (6) of the second drive set (6'). The main and adjacent shafts are located via bearings (8,8') in a complex control head (14).The control head has only one common suction chamber (15) as well as separate pressure chambers (16,16') for both drive sets and the filling pump. Fixed cylinders (19,19') for adjusting pistons (20,20') of the rocker (11) are located in the control head. A channel (17) connects the suction chamber in the control head to the leakage chamber (18) for the drive sets, as well as to the gears (9) of the main and adjacent shafts.
