    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.

    摘要: A scroll compressor is provided with a valve plate which selectively blocks communication between a tap and the back pressure chamber. The valve plate is configured such that it blocks communication during portions of the orbiting cycle and allows communication at other portions. In this way, a scroll compressor designer is able to select the portions of the compression cycle at which refrigerant is delivered to the back pressure chamber. A more consistent and stable operation of the scroll compressor can thus be achieved.

    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 having an apparatus for minimizing oil leakage during reverse running is provided. The compressor includes a suction tube for allowing gas to enter the compressor housing. One oil minimizing apparatus is a check valve disposed at the suction tube having a spring normally biased against the inlet suction tube so as to prevent oil from exiting the suction tube during reverse running of the motor of the compressor. An alternative oil minimizing apparatus is an oil dam extending longitudinally above the suction tube on an inner surface of the compressor housing. The oil dam bends circumferentially with the inner surface for draining oil along the inner surface away from the suction tube.
