Abstract
A scroll compressor has a device which may be actuated to limit the orbit radius of the orbiting scroll. The device is moveable between an unactuated position at which it is spaced from a hub for the scroll compressor, and an actuated position at which it limits the orbit radius of the hub. The device may be actuated when reduced capacity is desired.
Claims6
A scroll compressor comprising:
- a first scroll member having a base and a generally spiral wrap extending from said base;
- a second scroll member having a base and a generally spiral wrap extending from its base, said wraps interfitting to define compression chambers;
- said second scroll member having a hub extending away from its base in an opposed direction to said wrap, a shaft having an eccentric pin extending upwardly into said hub, and a slider block positioned between said eccentric pin and an inner periphery of said hub;
- and
- an orbit limiting device moveable between actuated and unactuated positions to contact said hub, and limit the orbit radius of said second scroll member when actuated.
