装置。 a stator having a plurality of arcuate teeth formed at equal intervals in the circumferential direction; a rotor consisting of a trochoidal tooth profile that rotates within the stator while meshing with the arcuate teeth; and a stator formed on the axis of the rotor. The stator is provided with a shaft that is connected in a hole that is connected to transmit rotation, a spacer that prevents the shaft from coming off, and a pair of plates that sandwich the stator from both sides and have a required clearance with respect to the rotor. In a trochoidal hydraulic system, pressure oil is sucked in and discharged by volume fluctuations accompanying the rotation of the rotor in each pressure chamber defined by the arcuate teeth of the rotor and the tooth profile of the rotor. A recess with a larger diameter than the hole is formed around the hole in the core, and a sealing mechanism is interposed in the recess to fit the spacer, thereby maintaining oil tightness between the pressure chamber and the inside of the rotor hole. This is a trochoid type hydraulic device.
