ABSTRACT:
A variable displacement hydraulic piston pump having a cylinder block provided with cylinder bores formed therein to receive reciprocatory pistons and capable of rotating together with an axial drive shaft, a swash plate pivotally supported to reciprocate the pistons in the cylinder bores in response to the rotation of the cylinder block thereby discharging pressurized oil, a resilient unit for constantly urging the swash plate to a small inclination-angle position, a hydraulic control cylinder capable of providing the swash plate with a controlled force moving the swash plate toward a large inclination-angle position, an input shaft connected to the drive shaft to transmit a rotary drive power rotating the drive shaft, and a torque limiter arranged between the input and drive shafts so as to be able to disconnect the drive shaft from the input shaft when an abnormal excessive load is applied to the drive shaft thereby protecting internal elements and parts of the pump from damage and breakage.
