Capacity control valve for a variable capacity refrigerant compressor |
摘要 |
A capacity control valve for a variable capacity refrigerant compressor for controlling the compressor capacity by adjustably changing a pressure level prevailing in a crank chamber of the compressor, the capacity control valve having a valve mechanism opening and closing a portion of a gas-supply passageway extending between a discharge chamber and the crank chamber of the compressor, and a discharge pressure responsive unit controlling a movement of the valve mechanism in such a manner that only when the discharge pressure of the refrigerant gas is below a predetermined pressure level, does the valve mechanism reduce the opening area of the portion of the gas-supply passageway due to a force provided by the discharge pressure responsive unit in addition to a different force produced by the discharge pressure of the refrigerant gas. The capacity control valve enables the compressor to produce a satisfactory refrigerating performance irrespective of the environmental temperature.
