圧モータ。 A valve body is provided that rotates integrally with the output shaft, and the rotating action of this valve body switches between a high-pressure oil passage and a low-pressure oil passage, and the high-pressure oil is applied to the inner rotor of the trochoid gear. In a hydraulic motor configured to rotate a rotor and extract its torque, one side of the valve body is rotatably contacted with the body side, the other side is rotatably contacted with the trochoid gear side, and the valve body The shape and phase on both contact surfaces are the same, so that the pressure receiving area on both sides of the valve body is approximately equal, and the valve body has a plurality of oil passages parallel to the axis on the side opposite to the trochoid gear. A first annular groove that constantly communicates with the first inflow/outflow port and a second annular groove that constantly communicates with the second inflow/outflow port are formed on the outer periphery of the valve body. The first annular groove and the second annular groove are alternately communicated with the oil passage, and the high pressure from the oil passage acts also on the side of the valve body opposite to the trochoid gear, Equalize the pressure action on both sides of the valve body,
A hydraulic motor configured to hydraulically float the valve body.
