<p>PROBLEM TO BE SOLVED: To provide a valve device which is of simple construction, low in the manufacturing cost, and provided with two, independent valves. SOLUTION: In order to control the flow of fluid, the valve device 1 is provided with two, independent valve elements 4, 5 arranged so than they can move in cooperation with return springs 7, 8 respectively, in its two valve chambers V1, V2. In this case, the two valve chambers V1, V2 are arranged in axial direction in two housings 2, 3 respectively. A separating means 6 for separating these valve chambers apart from each other and supporting each end of both the return springs 7, 8 is fixed between both the valve chambers. A common discharge fluid opening 15 connected to space parts 10, 11 provided respectively in the valve chambers, is arranged in the housings, and a pair of single way valves 9, 9' for preventing the passage of fluid between both the valve chambers are installed-arranged between the discharge fluid opening and the respective valve chambers.</p> |
