Abstract
A variable quantity control apparatus for a variable radius type scroll compressor comprises: a rotary shaft coupled to an orbiting scroll for transmitting a rotating force of a driving motor to the orbiting scroll; and an eccentric bushing coupled to a driving pin part of the rotary shaft for transmitting the rotating force of the driving motor and at the same time, for restraining a recession amount of the orbiting scroll, whereby manufacturing cost can be reduced because an additional stopper member can be excluded and the number of components and the number of assembling processes are reduced, and the recession of the eccentric bushing (or the orbiting scroll) can be stably restrained by the surface contacting of a cut surface of the rotary shaft and stopping surfaces of the eccentric bushing.
