    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： A scroll compressor includes an adjustable actuator mount that changes the relative position of a non-orbiting scroll and an orbiting scroll to change the compressor capacity. In one embodiment, the scroll wrap and base of each scroll are manufactured as two separate components with a wrap modulator between the scroll wrap and the base of each scroll. As the mount moves the scrolls apart and together, the wrap modulators extend and retract the scroll wraps relative to their respective bases to maintain fluid-tight compression chambers.

    摘要： An improved heat shield for a scroll compressor is provided with a non-cylindrical end portion caught between the end cap and the non-orbiting scroll. In several embodiments, the portion provides a seal between the discharge chamber and a suction chamber. In one embodiment the portion of the heat shield is serpentine. In another embodiment the portion of the heat shield is generally u-shaped. In further embodiments the portion includes a plurality of circumferentially spaced clips. Several other embodiments are also disclosed.

    摘要： A scroll compressor includes first and second scroll members having wraps interfitting to define compression chambers. As is known, a back pressure chamber is defined to hold the two scroll members in contact with each other. A valve is positioned to selectively block flow of refrigerant into the back pressure chamber, but is condition responsive to change the flow of refrigerant into the back pressure chamber dependent on conditions within the compressor. In one embodiment, the valve normally blocks a second tap which communicates with discharge pressure. If an elevated temperature is reached the valve moves to an open position and refrigerant can flow from the discharge pressure chamber into the back pressure chamber. In another embodiment, the valve selectively closes a lower pressure tap.
