ABSTRACT:
An air compressor having a main pressure line connected to an object to be inflated and an accumulator connected to the main pressure line through a restrictor to receive an average of the output pressure during the pumping stroke and to receive, at other times, the actual object pressure so that the pressure in the accumulator corresponds to the pressure in the object, and a relief valve responsive to the pressure in the accumulator for connecting the accumulation to atmosphere when a pressure preselected by a regulator is obtained in the object.
