Title:
SURFACE PRESSURE LOAD DEVICE OF SLIDE VALVE
Document Type and Number:
WIPO Patent Application WO/2005/042191
Kind Code:
A1
Abstract:
Relative sliding between a surface pressure releasing plate and a surface pressure releasing bar can be smoothed by equalizing compression of compression springs. A surface pressure load device of a slide valve is constructed such that relative sliding between a surface pressure releasing plate (13) and a surface pressure releasing bar (15) is smoothed by equalizing compression of compression springs (11) when surface pressure is applied and released. The equalization is achieved by making the arrangement center (A) of projection bodies (14) of the surface pressure releasing plate (13) and the arrangement center (B) of the compression springs (11) agree with each other.
