AXIAL-PISTON HYDRAULIC MACHINE Russian patent published in 2000 - IPC

Abstract RU 2158851 C2

FIELD: mechanical engineering. SUBSTANCE: axial-piston hydraulic machine has cylinder block with pistons contacting the inclined disc through shoes and positioned in bushings secured rigidly in cylinder block. Bushings are provided with discharging holes located at angle of 120 deg. in zones of maximum contact spots from side of working chamber. Some discharging holes are shifted relative to others through angle of 60 dwg. Discharging holes are coupled to working chamber by means of channels. Working fluid is brought to discharging grooves through channels, thus creating force which presses out plunger from bushing. EFFECT: enhanced efficiency. 5 dwg
