Abstract

DC60 (20/10/41) Problem: To improve the efficiency of the pump for a DC compressor by controlling the back pressure of the pump piston. Solution: The pump body 20 is provided with an actuation chamber 37, which is hermetically sealed with the connection between the crankshaft of pump 26 and the pump piston 25, and contains air leaking from pump chambers 361 and 362 through the outer circumference of the pump piston 25 and a pressure reducing end 75, which opens when the pressure in actuation chamber 37 rises to a predetermined value or more to release the excess pressure into the low-pressure sections 52 and 551.
