摘要： A spacer is positioned between an outer periphery of a motor stator, and the inner periphery of a center shell for a sealed compressor. The spacer allows a relatively small diameter motor to be used in a relatively large diameter center shell. The spacer includes a bearing mount in a lower plate, and a plurality of axially extending fingers positioned between the stator and the center shell. The spacer also includes a stop for proper positioning of the stator within the center shell.

摘要： A vent is included into a scroll compressor for protecting a refrigerant system in the event of loss of charge. The vent selectively taps an entrapped compression chamber to a housing chamber which surrounds the motor. In the event of a low charge, the gas in the compression chamber will be at a high temperature, and will heat the motor when the vent opens. The vented heated gas will then actuate a temperature protection device on the motor, causing the motor to stop rotation. In further embodiments, the compression chamber which supplies the tapped fluid is the discharge port.

摘要： A scroll compressor includes a plurality of components which are force-fit together. The components include the separator plate, a pressure relief valve mounted in the separator plate, and a discharge tube. By force-fitting these components, the necessity of welding operations in the interior of the scroll member is eliminated. This will reduce the occurrence of weld splatter, which is undesirable. Further, the assembly of the scroll compressor is simplified by this invention.

摘要： An improved housing for scroll compressor has the end cap housing formed integrally with the fixed scroll member. The end cap housing is preferably welded to a tubular housing enclosing the scroll compressor. Most preferably, the end housing has inner and outer tubular portions and the tubular housing extends upwardly into a channel between the inner and outer tubular portions. A muffler is preferably formed integrally with the end cap and extends to a side of the end cap. The present invention further includes heat transfer fins extending from the end cap. The positioning of the muffler to the side decreases the overall length of the compressor. The use of the fins increases the efficiency of compression as heat is removed from the compression chambers. The use of the unique combined end cap and fixed scroll which is welded to the tubular housing simplifies assembly.

摘要： A scroll compressor (10) is disclosed which incorporates, in the first embodiment, a floating seal (50) having an inner face seal (52) and an outer face seal (54). The floating seal also has inner and outer diametric seals (58, 60) to seal against the walls of a recess (41) in the crankcase (36). The axial thickness of the floating seal exceeds the depth of the recess. As the scroll compressor undergoes start-up, the orbiting scroll element (14) is forced against the face seals (52, 54) to create a sealed chamber (40). Intermediate pressure from a compression pocket between the scroll elements pressurizes chamber (40) defined between the seals to force the orbiting scroll element (14) into engagement with the fixed scroll element (12). In a second embodiment, a floating seal (80) uses actuator piston (88) which is urged into continuous sealing contact with the orbiting scroll element (14) by an actuator spring (92) to create a sealed chamber. Upon start-up, the chamber (96) is provided with intermediate pressure gas which urges the orbiting scroll element (14) into engagement with the fixed scroll element (12).

摘要： A number of scroll compressor designs protect the back chamber seals upon reverse rotation. In the prior art, scroll compressors are sometimes miswired and inadvertent reverse rotation results. In some applications, this has caused the seals to be crushed. The present invention ensures that upon reverse rotation, the pressure within the back chamber is maintained at suction pressure rather than the very low pressure which may be found in the compression chambers. The seals are protected. In one embodiment, a relief is formed at a seal groove to ensure suction pressure does communicate into the back chamber. In other embodiments, a valve controls the pressure in the back chamber. Upon normal operation, the valve allows pressure from the back pressure tap to communicate into the back chamber. During reverse rotation, the valve allows suction pressure to communicate to the back chamber.
摘要翻译： 许多涡旋压缩机设计在反向旋转时保护后室密封。 在现有技术中，涡旋式压缩机有时会出现连线错误，导致无意的反转。 在一些应用中，这导致密封件被压碎。 本发明确保在反向旋转时，后室中的压力保持在吸入压力而不是在压缩室中可以发现的非常低的压力。 密封件受到保护。 在一个实施例中，在密封槽处形成浮雕以确保吸入压力连通到后室。 在其他实施例中，阀控制后室中的压力。 在正常操作时，阀允许来自后压力抽头的压力连通到后室。 在反向旋转期间，阀允许吸入压力与后室连通。

摘要： Rolling element bearings are located between the eccentric drive pin and the slider block of a scroll compressor. The rolling elements reduce static or boundary lubrication friction by an order of magnitude in providing rolling friction. As a result, movement of the orbiting scroll into and out of flank contact is facilitated and scroll separation takes place earlier in the shutdown process.

摘要： An eccentric drive pin is located on the overhung end of a crankshaft. The drive pin is located within a bore in a slider block which is located within the hub of an orbiting scroll. Either the drive pin or the slider block bore has an axially curved surface and the other has a corresponding flat surface parallel to the axis of the crankshaft. Contact between the axially curved and corresponding flat surface remains at essentially the same axial location even though the drive pin is deflected under loading.
