PURPOSE:To utilize effectively discharge pressure fluid from a pressure fluid source by limitting outflow flow of the pressure fluid supplied from the pressure fluid source to a tank to a small flow when current is not supplied to an electromagnet. CONSTITUTION:When current is not supplied to an electromagnet, a poppet valve 26a connected to a movable iron core is completely spaced from a valve seat 33a. Discharge fluid from a pressure fluid source flows to a tank T through a piping 4, a throttle 30a of a valve body 24a, a spring chamber 29a, a throttle port 28a, a path 32a and a discharge chamber 20a. Then, the valve body 24a moves left against the press force of a spring 27a in response to flow resistance of the throttle 30a. Thus, an end 31a of the valve body 24a throttles the throttle port 28a of reduce ineffective flow flowing from the pressure fluid source to the tank T. |
