Abstract

PURPOSE:To restrain generation of a negative pressure in case of a high piston speed by forming a valve with a central hole separately and inserting it into an eddy chamber to be reciprocated in such a manner as to function as a check valve in addition to the function of the central hole. CONSTITUTION:When a piston 3 descends, orifice resistance is always produced in a central hole 8 by a flow of working liquid. Especially in cacse of a high piston speed, a valve 16 is pushed upward by a flow of working liquid against a coil spring 17 to function as a check valve, wherein working liquid flows from a liquid chamber R2 through the central hole 8 and a notched groove 15 into an eddy chamber 6 and flows out into a liquid chamber R1. Accordingly, in such a case, the orifice resistance is reduced by a large margin as compared with a conventional case, resulting in preventing generation of a negative pressure even if the diameter of the central hole 8 is set smaller.
