Abstract: A compressor includes orbiting and non-orbiting scrolls forming first and second fluid pockets therebetween. First and second ports are disposed in the non-orbiting scroll and radially spaced apart from each other. The first port communicates with the first pocket at a first radial position and the second port communicates with the second pocket at a second radial position. A blocking device is movable between a first position preventing communication between the ports and a fluid source and a second position allowing communication between the ports and the fluid source. The first and second pockets have first and second pressures, respectively. One of the pressures may have a disproportionate pressure change compared to the other of the pressures after at least one of the pockets communicates with the fluid source through at least one of the ports. The disproportionate pressure change biases the orbiting scroll relative to the non-orbiting scroll.

Abstract: A compressor includes orbiting and non-orbiting scroll members meshingly engaged to form a series of compression pockets, including first pockets when the orbiting scroll member is in a first position. A first porting in the non-orbiting scroll member communicates with the first pockets during a portion of a compression cycle. The first pockets include a set of radially outermost pockets located radially inward relative to the first porting and isolated from communication with the first porting during the compression cycle. The first porting is aligned with a spiral wrap of the orbiting scroll member at a location radially outward from and directly adjacent the first pockets when the orbiting scroll member is in the first position. Additional porting communicates with each of the compression pockets located radially outward relative to the first pockets when the orbiting scroll member is in the first position.
