Abstract

PURPOSE:To reduce the size and weight of a scroll hydraulic machine by recessing a portion of the back face of a seat for a swivel scroll and then burrying a portion or the entirely of the ring section of an Oldham's ring in said recess. CONSTITUTION:A scroll hydraulic machine comprises a fixed scroll 1, a swivel scroll 3 and an Oldham's mechanism A. The back face of the seat 3b for the swivel scroll 3 is recessed and a key groove 3c is provided in said recess 3c. A key groove 4a is provided in the frame 4 while being crossed perpendicularly with the key groove 3c of the swivel scroll 3. The ring 5a of an Oldham's ring 5 is arranged in the recess in the back face of the seat 3b for the swivel scroll 3. Since the distance between the seat for the swivel scroll and the main bearing for the frame can be shortened, the size and the weight of the scroll hydraulic machine can be reduced.

As shown in FIG. 3, the Oldham ring 5 is integrally formed with a ring-shaped ring 5a and a key-shaped projection 5J, and the cow-shaped projection 54 is engaged with the key grooves 8C and 4C, respectively. The ring 5a of the Oldham ring 5 is self-installed in a concave circle on the back surface of the pedestal 8 of the orbiting scroll 8.
