  • Valve apparatus and method for controlling fluid flow
    Patent number: 5197508
    Abstract: A valve device and method for controlling the operation of the valve device, in particular a proportionally acting solenoid valve, consisting of a valve housing in which several pressure fluid chambers provided with pressure fluid connections are present, having two valves which are arranged within the valve housing and are providing with moveable valve members, the valve members being connected to a valve rod which serves for actuation.In order to simplify the construction of the valve, and provide reliable and reproducible detection and control of the valve opening cross section, two valves members (4, 5) and (12, 13) of the two valves are arranged coaxially and are jointly connected to a valve rod (20), actuatable simultaneously with it. A pressure fluid chamber is arranged between the valves.
