驱动扭矩由驱动轴 通过十字联轴器 传递给星形的液压缸体转子，定于不受其它横向作用力。转于装在配流轴上。位于转子中的径向布置的柱塞，通过静压平衡的滑靴紧贴着偏心行程定子。柱塞与滑靴球铰相连，并通过卡簧锁定。二个保持环将滑靴卡在行程定子上。泵转动时，它依靠离心力和液压力压在定于内表面上。当转子转动时，由于定于的偏心作用，柱塞将作往复运动，它的行程为定于偏心距的2倍。定子的偏心距可由泵体上的径向位置相对的两个柱塞来调节。 油液的进出通过泵体和配流轴上的流道，并由配流轴上吸油口控制，泵体内产生的液压力被静压平衡的表面所吸收。摩擦副的静压平衡采取了过平衡压力补偿方法，形成了开环控制。支承驱动轴的轴承只起支承作用，不受其他外力的作用。

Drive torque from the drive shaft passing through the cross coupling to Star of the hydraulic cylinder rotor, will be held from other lateral forces. Turn on the shaft installed in the assignment. In the rotor radial arrangement of the plunger, through the hydrostatic balance of the sliding shoe close to the eccentric line Chengding Zi. Plunger and sliding the ball joints boots connected by retainer lock. 2 maintain the ring will slide on the boot card line Chengding Zi. Pump rotation, it relies on centrifugal force and the hydraulic pressurizing the inner surface in the set. When the rotor rotates, the eccentric role as scheduled, the plunger will be reciprocating motion, it is scheduled to travel to 2 times the eccentricity. By the pump stator eccentricity relative radial position on the plunger to adjust the two. Oil pump and the distribution of access through the axis of the flow stream by the suction port to control flow distribution shaft, pump hydraulic pressure produced by the body to be absorbed by the surface of static equilibrium. Friction has taken over the static pressure balance equilibrium pressure compensation, the open-loop control form. Bearing drive shaft bearing only play supporting roles, not the role of other external forces.
