Title:
PISTON-TYPE ACCUMULATOR
Document Type and Number:
Japanese Patent JPS60188602
Kind Code:
A
Abstract:
PURPOSE:To keep the fluid pressure in a pressure fluid chamber high all the time and prevent the leakage of gas by providing in a through path, which connects the pressure fluid chamber of a piston with a fluid chamber, a check valve which allows one-way flow of fluid from the fluid chamber to the pressure fluid chamber. CONSTITUTION:A chamber 27 in a closed-end round hole is connected to a pressure fluid chamber 24 by use of a through hole 28, in which a working fluid is contained. The chamber 27 is connected to a through path 29, and a check valve consisting of a ball valve 31 and a compression coil spring 32 is set on a tapered valve seat 30 formed at the inlet of the chamber 27. In this way, an arrangement is made so that the fluid pressure in a pressure fluid chamber 17 is applied to the pressure fluid chamber 24 through the check valve having a ball valve 52, and therefore, the fluid pressure in the pressure fluid chamber 24 is kept high, reducing the pressure gradient; thus the leakage of gas can be prevented.
