3 Introduction In axial piston pumps, the pistons reciprocate parallel to the axis of rotation of the cylinder block. he simplest type of axial piston pump is the swash plate in-line design. he cylinder block in this pump is turned by the drive shaft. Pistons fitted to bores in the cylinder block are connected through piston shoes and a shoe plate, so that the shoes bear against an angled swash plate causing the pistons to reciprocate. he ports are arranged in the valve plate so that the pistons pass the inlet as they are pulled out and pass the outlet as they are forced back in. he displacement of axial piston pumps is determined by the size and number of pistons, as well as the stroke length which is determined by the angle of the swash plate. Variable Displacement Piston Pumps are used in closed loop systems either as a single or tandem pump. Oil is circulated by the pump to the motor and then returned directly back to the pump. charge supply is used to supplement the closed loop system with oil. he charge supply may be supplied by an internal charge pump (standard) or an external source. ypical applications Harvester equipment Combines Fruit or vegetable pickers Swathers Forestry equipment Log skidders ark removers Limb removers Construction equipment renchers Skid steer loaders Utility vehicles Sweepers urf care equipment Mowers Paving equipment Rollers Packers Industrial equipment Lift trucks Scissor lifts Valve plate slot 2...and are forced back in at outlet Piston subassembly Outlet port Inlet port Swash plate Shoe plate Cylinder block bore Piston withdraw from bore at inlet EON Medium Duty Piston Pump E-PUPI-MC7-E2 pril 27 3
