Abstract
A method of controlling the capacity of a variable capacity wobble plate compressor from an air conditioning system wherein the compressor capacity is controlled such that the degree of communication between a suction chamber and a crankcase is controlled by a pressure control valve to vary the crankcase pressure and hence the angularity of the wobble plate. The value of at least one parameter representing thermal load is detected, the magnitude of current to be supplied to an electromagnetic actuator of the pressure control valve is determined in response to the detected parameter value, and the opening of the pressure control valve is determined in response at least to the determined magnitude of current.
