Abstract
A compressor may include a first scroll, a second scroll and a modulation system. The first scroll may include a first endplate and a first spiral wrap. The second scroll may include a second endplate and a second spiral wrap interleaved with the first spiral wrap and cooperating to form a plurality of working fluid pockets therebetween. The modulation system may include a temperature-responsive displacement member that actuates in response to a temperature within a space rising above a predetermined threshold. Actuation of the displacement member may be controlled to control a capacity of the compressor.
Claims11
A compressor comprising:
- a first scroll including a first endplate and a first spiral wrap;
- a second scroll including a second endplate and a second spiral wrap interleaved with said first spiral wrap and cooperating to form a plurality of working fluid pockets therebetween, said first endplate including a first passage and a second passage, said first passage in communication with an intermediate one of said working fluid pockets;
- and
- a modulation system including a modulation member and a temperature-responsive displacement member, said modulation member engaging said first endplate and movable relative to said first endplate between a first position in which said modulation member blocks communication between said first and second passages and a second position in which said modulation member is spaced apart from said first passage to allow communication between said first and second passages, said temperature-responsive displacement member engaging said modulation member and actuating to axially move said modulation member between said first and second positions.
