Abstract (en)
A scroll-type machine comprising: a first scroll member having an end plate and a first spiral wrap upstanding therefrom; a second scroll member having an end plate and a second spiral wrap upstanding therefrom, said first and second scroll members being positioned with said first and second spiral wraps interleaved with each other; a fixed support structure for supporting said first and second scroll members for relative orbital movement therebetween whereby said first and second spiral wraps define sealed moving fluid pockets which progressively decrease in size as they move from a radially outer position to a radially inner position; a power source coupled to said first scroll member and operative to effect said relative orbital movement between said first and second scroll members; and a device selectively actuable to effect relative radial movement between said first and second scrolls to thereby form a leakage path between said moving fluid pockets while said power source continues to operate whereby the capacity of said compressor is reduced, said device being independent of said coupling of said power source to said first scroll. <IMAGE>
