<p>PURPOSE: A spool type selector valve is provided to improve the compactibility and the processing performance of a valve body since the diameter does not decrease from the central part to both ends. CONSTITUTION: A spool type selector valve(10) comprises a valve body(11), a valve hole, a fluid feeding path(P), a fluid outlet path, a fluid discharge path(E1), a feeding valve seat, a discharge valve seat, a sealing cylinder, a sealing member and an elastic member. The valve hole is formed on the valve body. The fluid feeding path communicates with the valve hole. The fluid outlet path communicates with both sides of the fluid feeding path. The fluid discharge path communicates with the valve hole on the end of the hole than the fluid outlet path. The feeding valve seat is formed on the valve hole between the fluid feeding path and the fluid outlet path. The discharge valve seat is formed on the valve hole between each fluid outlet path and each fluid discharge path. The sealing cylinder is formed on the valve hole. The sealing member is slidably inserted into the valve hole. The elastic member makes the sliding contact with the sealing cylinder.</p> |
