A scroll compressor utilizes scroll wrap profiles which are designed with a rapid compression scroll wrap profile. This profile utilizes a shorter wrap and lower vane aspect ratios during the compression process. The non-orbiting scroll member is integrated with the main bearing housing. The drive shaft extends through the main bearing housing, through the non-orbiting scroll member and through the orbiting scroll member. In one embodiment, a counterweight is disposed adjacent the orbiting scroll member. In another embodiment, and upper bearing housing is disposed adjacent the orbiting scroll member. In yet another embodiment, an upper bearing housing is disposed adjacent the orbiting scroll member with a counterweight disposed adjacent the upper bearing housing.

A scroll compressor an orbiting scroll member including a second end plate, a second wrap extending from the second end plate and meshingly engaged with the first wrap to form a suction pocket in fluid communication with a suction pressure region of the compressor, intermediate compression pockets, and a discharge pocket in fluid communication with the discharge passage. An auxiliary passage is in fluid communication with one of the intermediate compression pockets to provide pressurized fluid to the chamber to deflect the first end plate and the first wrap axially toward the orbiting scroll member.

A scroll compressor includes an orbiting scroll member having an orbiting end plate defining a discharge port and an orbiting spiral wrap extending from the orbiting end plate. The compressor also includes a non-orbiting scroll member having a non-orbiting end plate and a non-orbiting spiral wrap extending from the non-orbiting end plate. The non-orbiting spiral wrap is intermeshed with the orbiting spiral wrap. Furthermore, a bearing housing extends from the non-orbiting end plate opposite from the non-orbiting spiral wrap, and a drive member causes the orbiting scroll member to orbit relative to the non-orbiting scroll member whereby said spiral wraps create pockets of progressively changing volume between a suction pressure zone and a discharge pressure zone. The drive member extends through the bearing housing, the non-orbiting scroll member and the orbiting scroll member. Also, the scroll compressor includes a discharge valve for controlling fluid flow through the discharge port.

A scroll compressor is provided and may include an orbiting scroll member having an orbiting end plate and an orbiting spiral wrap extending from the orbiting end plate. The scroll compressor may also include a non-orbiting scroll member having a non-orbiting end plate and a non-orbiting spiral wrap extending from the non-orbiting end plate and intermeshed with the orbiting spiral wrap. The scroll compressor may further include a drive member for causing the orbiting scroll member to orbit relative to the non-orbiting scroll member and a discharge slot formed by one of the orbiting scroll member and the non-orbiting scroll member. A discharge valve may be rotatable with the drive member and may operate between a closed state preventing fluid communication between the pockets and the discharge slot and an open state permitting fluid communication between the pockets and the discharge slot.

A scroll compressor includes a capacity modulation system. The capacity modulation system has a piston that is connected to the non-orbiting scroll that disengages the non-orbiting scroll from the orbiting scroll when a pressure chamber is placed in communication with the suction chamber of the compressor. The non-orbiting scroll member moves into engagement with the orbiting scroll when the chamber is placed in communication with the discharge chamber. The engagement between the two scrolls is broken when the pressure chamber is placed in communication with fluid from the suction chamber. A solenoid valve controls the communication between the pressure chamber and the suction chamber. By operating the valve in a pulsed width modulated mode, the capacity of the compressor can be infinitely varied between zero and one hundred percent.

A scroll compressor has a fluid pressure biasing system for both the orbiting scroll member and the non-orbiting scroll member. The biasing system can utilize a pressurized gas from the pocket of the scroll compressor or it can utilize an external pressurized oil source. In an additional embodiment, a hydrostatic bearing is located between the orbiting scroll member and the non-orbiting scroll member.

A compressor may include a shell assembly, a first scroll member located within the shell assembly and including a first end plate and a first spiral wrap extending from the first end plate, and a second scroll member located within the shell assembly, supported for orbital movement relative to the first scroll member and including a second end plate and a second spiral wrap extending from the second end plate and meshingly engaged with the first spiral wrap to form compression pockets. The first scroll member may define a fluid injection port and the second scroll member may define a passage in communication with the fluid injection port and at least one of the compression pockets to provide pressurized vapor from the fluid injection port to the at least one of the compression pockets.
