式流体圧縮装置。 ゛ ′ ・A first scroll member having a lozenge winding body fixed on one side of a plate and a second scroll member having a spiral winding body similarly fixed on one side of the plate body are connected by adjusting the angle of both spiral winding bodies. The first scroll member is moved relative to the second scroll member so as to rotate in a circular orbit while being prohibited from rotating, and the first scroll member is moved relative to the second scroll member so that the first scroll member is overlapped while being shifted and meshed with each other. The fluid is taken in while forming a space, and as the first scroll member moves, the space is moved toward the center and the volume is reduced, so that a unidirectional continuous flow compression action is performed. In the positive displacement fluid compression device, a radial bearing is provided in a housing containing the first and second scroll members, lubricating oil accumulated in the housing, and a front end plate forming one axial end surface of the housing. a main shaft inserted and supported through the main shaft, a mechanical seal pocket provided at the outer end of the housing of the radial bearing of the main shaft and blocked from the outside, and provided on the opposite surface of the plate of the first scroll member, A cylindrical protrusion fitted to the outer periphery of the tip of the crank pin eccentric from the main shaft via a radial bearing, and a large diameter protrusion provided on the main shaft and facing the inward surface of the front end plate via a thrust bearing. a rotor, an oil deflector provided on the upper inner surface of the housing facing the rotor circumferential surface, and an oil deflector provided on the front end plate, one end opening near the oil deflector and the other end opening into the mechanical seal pocket. a first oil passage; and a second oil passage provided across the main shaft and the crank pin, one end of which opens into the mechanical seal pocket, and the other end of which opens into the shaft end surface of the crank pin; 2
The distance r from the opening at one end of the oil passage to the axis of the main shaft, and the distance R from the opening at the other end to the axis of the main shaft,
A positive displacement fluid compression device characterized by being set to satisfy the relationship R>r.゛ ′・
