Abstract: An improved valve mounting assembly for a hermetically sealed compressor. The valve mounting assembly includes a valve, a damper, and a retention yoke. The valve, valve damper, and retention yoke cooperate to provide a valve mounting arrangement having high efficiency and low noise. The retention yoke includes an extension which is received between a yoke attachment and a valve plate. The extension is formed from a vibration attenuating material and reduces the communication of vibrations from the valve and valve plate to the yoke attachment. The retention yoke retains the valve and damper in position, and serves as a bumper to back up the damper and limit movement of the damper and valve.

Abstract: Improved refrigeration system, in particular for domestic use, with a compressor (2), a condenser (3), an evaporator (4) and a valve (5) arranged between the condenser (3) and evaporator (4). The system includes a three-way valve (6) between the condenser (3) and the compressor (2) which establishes a bypass (7) between the compressor (2) and the suction pipe (8) of the system (1) during stoppage of the compressor (2) which blocks the reflux of refrigerant contained in the condenser (3) to the compressor.
