Abstract

PURPOSE: To provide a small-sized switch valve without an inferior effect given when an exhaust gas is throttled, by disposing spring-loaded resilient pistons at the both ends of a vacant spool and forcing their external ends to contact the interior face of a valve body, thereby keeping the spool in a neutral position.
CONSTITUTION: A load of a spring 23 makes both resilient pistons 21, 22 contact left and right covers 20, 20 and projections 22 on the pistons contact the interior faces of covers 12, 12, respectively, thereby keeping a spool 18 in a neutral position. While a pilot pressure is applied on the left side of the spool 18 to make a right shift, the projection 22 of the right resilient piston 21 enters the spool 18, with the end of the projection 22 pressed on the cover 12 to a stop. An inport 13 and a left out port 14 and a right out port 14 and a right exhaust port 15 become intercommunicative. If a throttle is connected to the port 15, the spool 18 is shifted right with ease.
