EXCERPT:

HYDRAULIC PUMP ASSY E385B

Operation

The pump assy is equipped with two pumps arranged on the same axis that are connected with gear (116) and distribute the rotating power to the gear trains on a different axis. Thus the engine rotation is transmitted to front shaft (111) that drives the two pumps and, at the same time, drives the pilot gear pump arranged on another shaft.

The pump assy consists largely of:
- the rotary group, the main part of the pump that makes rotary on;
- the swash plate group that changes the delivery rate;
- the valve block group that selects between oil suction and delivery;
- the PTO group that transmits the drive power to the gear pump.

ROTARY GROUP

The rotary group consists of shaft (111), cylinder block (141), piston (151), shoe (152), plate (153), spherical bushing (156), and cylinder spring (157). The shaft is supported by bearings (123) and (124) at its both ends. The shoe, which is caulked to the piston, forms a spherical joint and relieves it of thrust force that is generated by load pressure.

Further, the piston is provided with a pocket so it moves lightly on shoe plate (211), taking hydraulic balance.

The sub group of the piston-shoe is pressed against the shoe plate by the cylinder spring, via the retainer plate and the spherical bushing, so that it moves smoothly over the shoe plate. The cylinder blocks (141) are also pressed against valve plates (313) or (314) by the action of cylinder spring (157).
