Abstract
A scroll-type fluid transferring machine comprises a stationary scroll member and an oscillatable scroll member, each of which has a spiral wrap of an involute curve or other curves projecting from a base plate and which cooperate to form a compression chamber between the spiral wraps and the base plates by mutually fitting one into the other, an oscillatable scroll shaft provided on the surface of the base plate at the position opposite the spiral wrap of the oscillatable scroll member, a crank shaft having an eccentric recess having its axis which is shifted by a predetermined distance from the axis of the crank shaft, wherein a cylindrical bush having the coaxial outer and inner circles is loosely fitted in the eccentric recess of the crank shaft with a gap between the outer circumference of the bush and the inner wall of said eccentric recess, and the shaft of the oscillatable scroll member is fitted in the inner circumference of the bush in a freely rotatable manner.
