CONTROLLED AXIAL-PISTON HYDRAULIC MACHINE Russian patent published in 1998 - IPC

FIELD: mechanical engineering; positive displacement drive. SUBSTANCE: shaft with flange is installed on supports in housing. Rotary distributor with high and low pressure ports made concentrically with its axis engages with cylinder block and with guide surface of housing cover provided with inlet and outlet ports. Distributor is made for turning relative to axis passing through point of intersection of shaft and cylinder block axes at acute angle to cylinder block axis. Outlets of high and low pressure ports of distributor and port of housing cover are arranged concentrically relative to axis of distributor rotation. Ports on side surface of distributor and ports on inner surface of housing coaxial with distributor ports are made in one plane at equal distance from point of intersection of axes of shaft and cylinder block. Length of arc of distributor ports pointed to housing does not exceed length of arc of bridges between housing ports. EFFECT: enlarged operating capabilities. 2 cl, 3 dwg
