| | | HOWTHEPUMPSOPERATE Wobble Plate Rotateswith Shaft During operation, a fixed angle wobble plate rotates with the drive shaft. The angled surface of the wobble plate imparts a reciprocating motion to the pistons which move in and out of the bores in the stationary barrel. During its suction stroke, each piston is filled through its inlet check valve. Fluid is drawn by vacuum into the piston pumping chamber in the barrel. Check ValvesControl Fluid During compression, the inlet check valve closes and pressure in the pumping chamber rises until it exceeds load pressure at the outlet port. The outlet checkball then lifts off its seat and fluid is pumped | | |
