<p>Structure of a plunger discharge type of fluid distributor valve equipped with a pilot spool mechanism. An object of the invention is to provide a means for providing discharge ports along the axis of the pilot spool, and another object of the invention is to provide a means for changing the number of discharge ports and the discharge rate. The pilot spool mechanism is arranged so that a spool chamber (2) (21 to 23) holding a pilot spool (1) (11 to 13) is formed by the use of a cylinder (7) (71 to 73), and a discharge nipple (8) (81 to 83) is fitted to either or both of the end portions of the cylinder. A fluid which is guided into an intermediate chamber in the pilot spool is introduced to an area in the vicinity of the middle portion of the discharge nipple through a discharge passage provided between the outer peripheral surface of the cylinder and the inner surface of a valve chest (bore) formed in a valve body (10), and is guided into a passage (44) communicating with a discharge port P formed in the discharge nipple, and is distributed from the discharge port P or P'.</p> |
