摘要： Seal structure for a scroll compressor is provided with localized magnetic surfaces. The seal is carried by one member and the magnetic surface coacts with a facing ferromagnetic surface to provide a seal therebetween even when the members are axially displaced and where there is orbiting motion therebetween.

摘要： A back pressure chamber seal for use in a scroll type compressor that is located between the adjacent surface on the back of the orbiting scroll and the machine casing. Seals are loosely received in endless grooves formed in one of the two adjacent surfaces and are magnetically held in contact against the other adjacent surface and one wall of the groove to provide a sealed region. A pressurized fluid is delivered into the sealed region to provide an axially disposed biasing force acting against the orbiting scroll.

摘要： A scroll-type compressor or other rotating machine employs a crankshaft having an integral counterweight to compensate for the off-axis orbiting motion of the device's orbiting scroll. The crankshaft is unitarily formed with a generally cylindrical crank portion at an upper end of the shaft, and with the counterweight formed immediately adjacent the crank. The counterweight is preferably in the form of a segment of a cylinder of smaller radius than that is disposed within the radius of the cylindrical passage of the stator. This permits the rotor and shaft assembly, with counterweight, to be assembled from below after installation of the stator.

摘要： Two annular pressure pockets are used to push the orbiting scroll against the fixed scroll to minimize leakage. One pocket is at intermediate pressure and the other is at discharge pressure. The pockets are defined by the orbiting scroll and an axial ring. In the preferred embodiment inner and outer seals are carried by the axial ring and an intermediate seal is carried by the orbiting scroll whereby the pressure pockets are of an eccentric configuration.

摘要： A linear compressor is provided. The linear compressor includes a casing that defines a chamber and a piston slidably received within the chamber of the casing. A driving coil is configured for selectively urging the piston to slide within the chamber of the casing. An electro-magnetic spring is configured for urging the piston towards a default position when the piston is positioned away from the default position. The electro-magnetic spring can permit the linear compressor to operate at a resonant condition.

摘要： A valve for selectively allowing the return of oil from a discharge plenum to a suction plenum includes a passage which is selectively opened or blocked by a valve spool. The valve spool sees a pressure from a discharge pressure location upstream of a discharge check valve on one face, and a discharge pressure from a discharge plenum on an opposed face. While the compressor is running, the two pressures should be relatively equal. The face which sees the pressure from the chamber upstream of the check valve is larger than the face which sees the pressure from the discharge plenum. Thus, when the compressor is running, the valve spool is biased to a first position at which it allows oil return from the discharge plenum to the suction plenum. However, upon shutdown of the compressor, the pressure in the chamber upstream of the discharge valve drops. The valve spool will be driven to a second position at which it blocks communication for oil return.
摘要翻译： 用于选择性地允许将油从排出气室返回到吸入室的阀包括通过阀芯选择性地打开或阻塞的通道。 阀芯从一个面上的排放止回阀上游的排出压力位置看到压力，以及来自相对面上的排放压力的排出压力。 当压缩机运行时，两个压力应相对相等。 看到来自止回阀上游的腔室的压力的面积大于看到排气室的压力的面。 因此，当压缩机运行时，阀芯被偏压到第一位置，在该第一位置允许压缩机从排出气室向吸入气室返回油。 然而，在关闭压缩机时，排出阀上游的室内的压力下降。 阀芯将被驱动到第二位置，在该位置阻止油回流的通信。

摘要： A thermostat for sensing an unduly high temperature in a sealed compressor, which is a scroll compressor in the disclosed embodiment, extends through the housing of the sealed compressor into the body of a non-orbiting scroll. Since the thermostat extends through the housing, the wires need not be sealed as they extend from the housing. Still, the thermostat is positioned close to the compression chambers and at a location that will quickly heat when undesirable conditions exist within the sealed compressor. In this manner, the present invention is able to rapidly respond to an undesirable situation to allow a system control to have an indication of the undesired condition.

摘要： In a scroll compressor, under conditions favoring reverse operation, the scroll wraps are separated so as to provide a continuous, unimpeded path through the scrolls. Spring bias, a repositioning of driving contact areas and/or force areas can be used singly or in combination to cause separation of the wraps.

摘要： A scroll compressor has a valve normally closed during forward operation of the scroll compressor. Upon reverse rotation, force imbalances allow the valve to open and communicate a chamber downstream of a check valve to a chamber upstream of the check valve. By communicating these two chambers, the detrimental effects of reverse rotation are reduced or eliminated. Two valve embodiments are disclosed. One embodiment also relieves unduly high discharge pressures. In a third embodiment, a pressure relief valve is provided to prevent desirably high pressure ratios or pressure differentials.
