    摘要: The object of the inventioin is to provide a pilot valve which is compact, prevents erroneous operation, and is inexpensive to manufacture. The pilot valve includes a valve body (1), inlet port (2) and outlet ports (3) formed in the valve body, spools (4) operable to interrupt/establish communication between the inlet port (2) and the outlet port (3), pistons (8) for slidably moving the spools (4), a lever (15), and a disk (14) adapted to transmit movement of the lever (15) and having a downwardly directed spherical recess (23). The valve body has a spherical projection (20) pivotably received in the spherical recess (23). A lever mounting shaft (13) is prevented from rotating about its own axis during operation of the lever.
