    摘要: A simplified drive arrangement is provided to allow a scroll compressor to be operated at two capacity levels by a reversible electric motor. A pair of one-way clutches are positioned on a pair of parallel shafts. When the motor is driven in a forward direction drive passes through one of the one-way clutches and directly to the orbiting scroll. However, when the motor is driven in a reverse direction, drive passes through a countershaft, which in turn passes through a second one-way clutch. The drive passing through the second one-way clutch will result in the orbiting scroll being driven at a distinct speed then when the motor is driven in a reverse direction. In this way, capacity modulation is achieved with a very simple mechanism.

    摘要: A number of improvements increase the flow of lubricant within a scroll compressor. A centrifugal oil separator is mounted on the discharge port to remove oil from the refrigerant. The oil is returned through a leak path such that the oil can easily return back to a suction pressure chamber. The leak path is preferably upstream of a check valve. Thus, at shutdown, the leak path will not allow upstream components to also equalize in pressure with the suction pressure chamber of the compressor. Further, a number of embodiments include ways of resisting flow of refrigerant through the leak path, while still allowing oil flow. A number of valve elements are described which perform this function. Alternatively, labyrinth flow paths, or positioning of the return paths such that it will be closed when the compressor is shut down are disclosed.

    摘要: A unique protection circuit for a sealed compressor incorporates oil structure which directs a heated oil onto a motor protection circuit. The motor protection circuit is of the type which shuts down operation of an electric motor when a predetermined temperature is sensed. The motor protection circuit is positioned adjacent to an oil return path which is opened when a high temperature is experienced in the compressor pump unit. The valve in the path opens to allow flow of the returned oil onto the motor protection switch. The motor protection switch is then actuated to stop further operation of the motor. In another embodiment, the motor protection switch is immersed in the oil sump. Again, when the oil temperature increases to a predetermined amount, the motor protection switch stops further operation of the motor.

    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.
