Claims

[Scope of utility model registration request]

A housing assembly includes a pair of side housings, a plurality of rotor housings whose inner circumferential surfaces are trochoidal surfaces, and at least one intermediate housing; A second eccentric shaft having at least one eccentric shaft portion formed at an appropriate axial position on the outside of the first eccentric shaft, and one end of the first eccentric shaft protruding outward in the axial direction from one end surface of the second eccentric shaft. the first eccentric shaft and the second eccentric shaft are fastened and fixed in the axial direction by a nut member attached to the one end of the first eccentric shaft; , a rotary piston engine having a plurality of rotors attached to each eccentric shaft portion of the drive shaft and rotating planetarily around the drive shaft,
An oil passage for supplying lubricating oil is formed within the first eccentric shaft, and one end of the oil passage is formed in the form of a deep hole on the one end side of the first eccentric shaft and along the axial direction thereof. A hydraulic control valve is opened to the outside through a valve fitting hole, and a hydraulic control valve is inserted into the valve fitting hole, and its axially outer end is held by a valve holder that is slidably fitted into the valve fitting hole.
