摘要： A scroll type compressor includes a fixed scroll member, a movable scroll member, an inlet, a discharge port, a discharge valve, a first pressure region and a second pressure region. The inlet is formed through the fixed scroll base plate. The discharge port is formed through the movable scroll member. The discharge valve opens and closes the discharge port. The first pressure region and the second pressure region defined at opposite sides of the movable scroll member apply pressure to the movable scroll member. Gas introduced through the inlet is compressed and highly pressurized in accordance with the movable scroll member orbiting with respect to the fixed scroll member. The highly pressurized gas is discharged from a compression region via the discharge port and the discharge valve. The compressor is provided with a communication passage so as to intercommunicate the first pressure region and the second pressure region during a predetermined period of a compression cycle established by the gas. The gas is flowed between both the pressure regions due to a pressure difference between both pressure regions at timing when the thrust force acting on the back surface of the movable scroll member is large.

摘要： Scroll compressor may include, for example, a stationary scroll, a drive shaft, a crank shaft coupled to the drive shaft, a bush coupled to the outer surface of the crank shaft and a movable scroll coupled to the crank shaft. The movable scroll is preferably disposed adjacent to the stationary scroll. A boss may be coupled to the movable scroll and the boss preferably protrudes from the movable scroll at the opposite side of the stationary scroll. A seal is preferably disposed in a clearance defined between the bush and the boss. A compression chamber is defined by a space between the stationary scroll and the movable scroll. Fluid is compressed within the compression chamber when the movable scroll revolves or orbits with respect to the stationary scroll. A discharge port is preferably defined within the movable scroll and is adapted to discharge compressed fluid to a side that is opposite of the stationary scroll.

摘要： A scroll compressor includes a fluid injection system. The fluid injection system includes a fluid passage which extends from a position outside of the shell of the compressor to the fluid pockets created by the wraps of the scroll members. The fluid passage extends through the orbiting scroll member. The fluid injection system can be used to inject gaseous or liquid refrigerant, lubricant or the fluid injection system can be used to vent the moving pocket to the suction area of the compressor for capacity modulation.

摘要： A rotating type machine including a first moving member having a first surface and a second member having a second surface slidably interfacing with the first surface. The first and second surfaces have relative movement therebetween, and one of the first and second members is supported by the other member through the interface of their respective first and second surfaces. At least one of the first and second surfaces is provided with at least one recess therein. A liquid lubricant is provided between the first and second surfaces, and the lubricant is received in the recess. Relative to the surface in which the recess is provided, the recess has a maximum depth which ranges between about 0.00125 and 0.0060 inches, and a surface area which ranges between about 1.767null10null4 and 1.963null10null3 square inches, whereby, during operation of the machine, a pressure spike is created in the lubricant above the recess, and first and second surfaces are hydrodynamically separated from each other by the pressure spike.

摘要： In a scroll compressor that can switch between an internal high-pressure operation and an internal low-pressure operation, in order to provide proper back pressure for an orbiting scroll during either operation, a back pressure chamber of the orbiting scroll is divided by means of a first and a second thrust rings into a first back pressure chamber in communication with a driving chamber and an independent second back pressure chamber, and the pressure in the second back pressure chamber is set at discharge pressure or suction pressure depending on an operation mode.

摘要： A scroll compressor has a pair of scroll members which compress a fluid as the fluid moves through pockets created by the scroll members. The fluid moves from a suction pressure zone to a discharge pressure zone. A chamber is defined by one of the scroll members. The chamber is in communication with a pocket located between the suction and discharge pressure zone such that an intermediate pressurized fluid is supplied to the chamber through a fluid passageway. The fluid passageway is designed to allow a large flow from the pocket to the chamber and a small flow from the chamber to the pocket. This dual flow capability reduces the pressure pulsation in the chamber. In one embodiment, a capacity control mechanism is associated with the compressor to vary the capacity of the compressor.

摘要： An improved compressor incorporates structure for facilitating the alignment of a suction tube with the motor stator windings. In one embodiment, the motor stator is provided with a protective coating such that the refrigerant entering the compressor housing through the suction tube does not damage the motor windings. In another feature, the chamber housing is bumped out in the location where the suction tube is mounted such that the distance between the radially inner end of the suction tube and the radially outer portion of the windings is increased. The above provides better protection for the motor windings in a sealed compressor wherein the suction tube is axially aligned with the motor windings.
