SLIDE VALVE DEVICE FOR AUTOMATIC SURFACE PRESSURE APPLICATION

摘要

To achieve increase in surface pressure application force and compactification of configuration in a slide valve device having a three-layer structure, in which a seal case is slid by means of a cam surface and movable bodies. The present invention provides a slide valve device for automatic surface pressure application including a slide valve having the three-layer structure, in which the movable bodies of the seal case is slidable on a support surface of a spring holder, the slide case and the seal case are coupled with each other by means of a coupling means or a coupling stopper, and the cases are slid together by means of an actuator so as to apply and release a surface pressure.
