PILOT VALVE.

摘要

This invention is directed to provide a pilot valve which is compact in size, does not easily cause an erroneous operation but can be produced at a low cost. In this pilot valve, a downwardly spherical recess (23) is formed in a disc (14) for transmitting the motion of a lever (15) to a piston (8) for sliding a spool (4) which cuts off/sets up communication between an inflow port and an outflow port (3) that are formed inside a valve main body (1) and a spherical protuberance (20) is formed on the valve main body side in such a manner as to be capable of fitting and rocking to the spherical recess. Furthermore, a lever fitting shaft (13) is constituted in such a manner as not to rotate with its axis as the center when the lever is operated.
