Title:
DISCHARGE CONTROL DEVICE FOR WORKING LIQUID OF ACCUMULATOR
Document Type and Number:
Japanese Patent JPS58118302
Kind Code:
A
Abstract:
PURPOSE:To prevent a phenomenon of erroneously enclosing a working liquid in a main body of an accumulator container by providing a closing valve of a supply discharge port with an auxiliary valve which works on a throttling part of said port to have the working liquid throttled before closure of said closing valve. CONSTITUTION:When working liquid is discharged at a high speed, a valve 15 is apt to close instantaneously toward a valve seat 21 due to a liquid flow. At this time, an auxiliary valve 20 is inserted in a throttle part (b). The working liquid flowing through a ring-like flow passage (c) between the throttle part (b) and the auxiliary valve 20 is gradually throttled and lowering in the speed of said liquid diametrically expands a plug 10 and further axially extends it while bringing it gradually in close contact with a container main body 1 from a fitting part side. Then, after the liquid is discharged, the valve 15 is restrained by the bottom part and closed. Accordingly, a phenomenon of erroneously enclosing the working liquid in the accumulator container main body is prevented.
