Abstract

PURPOSE: For preventing the sharp rise of the internal pressure of an automatic- valve provided chamber with simple construction and considerably decreasing the loss of motive power, to connect to said valve chamber a reflecting pipe which decreases said loss by making resonance of pressure wire in said valve chamber.
CONSTITUTION: A piston rod 4 is passed through the hole of an inner cover 13. Built in the wall portion forming a valve chamber 10 are a valve keeper 14 for pressing a suction valve 7 and a discharge valve 8 against a cylinder 5, and a cover 15 for pressing said valve keeper 14 so that no air may leak. A tip-closed reflecting pipe 16 is connected to the opening of said valve cover 15, the length thereof being fixed at 1/4 of that of the pressure wave in said valve chamber 10. Thereby, the mode indicated by two point chain line is developed inside said reflecting pipe 16, pressure change becomes large at pipe end and small at said valve chamber 10 so that pressure rise can be prevented and the loss of motive power can be decreased considerably.
