Abstract

See full text

A displacement control valve of a variable displacement compressor opens and closes a communication passage extending between a portion of the compressor on which discharge pressure acts and a crank chamber of the compressor. The displacement of the compressor is controlled, such that discharge chamber pressure does not act on the valve body in the opening and closing direction, and pressures acting on the opposite ends of the valve body are maintained at the same level.
