<p>PURPOSE: To compactly and inexpensively manufacture a valve for high pressure fluid. CONSTITUTION: A first valve seat 32 is formed in a valve housing 2, concentrically disposed in a valve chamber 4, and engaged with a movable valve member 12 at a first position. The first valve seat separates a drain passage 10 from an outlet passage 8 and a supply passage 6 but allows communication between the supply passage and the outlet passage. A second valve seat 40 is concentrically disposed in a cavity formed in the movable valve member, and engaged with one end part of a floating pin 16 to separate the supply passage from the outlet passage and the drain passage, but allows communication between the outlet passage and drain passage. An actuating device 22 is mounted on the valve housing adjacent to one end part of the movable valve member opposite the floating pin, advances the movable valve member toward a second position when it is energized, and allows the movable valve member to return to the second position when it is deenergized.</p> |
