Internal gear device with improved rotary valve |
摘要 |
A gerotor device wherein a body (10) includes high pressure ports (20) that communicate with an inlet (12) and low pressure ports (22) that communicate with an outlet (14). An inner member (42) and an outer member (40) cooperate to define pressure chambers (52) that increase and decrease in volume as the member (42) orbits and rotates. A rotary valve (62) selectively connects pressure chambers (52) to pressure ports (20) and (22) to convert between mechanical torque and fluid pressure. Cavities (75) and (77) are provided adjacent rotary valve (62) to hydraulically balance the valve.
