초록 ▼

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. A permanent magnet (9) is arranged on or in the valve rod (20) for detecting the position of the valve rod in such a manner that the range of the displacement path produced by actuation of the valve rod lies within the pressure fluid chamber (10). A field sensor 29 extends through the valve housing wall into the corresponding pressure fluid chamber (10).

대표청구항 ▼

A proportionally acting solenoid valve device, operable by a proportionally acting solenoid, comprising: a valve housing having a wall and a pressure fluid chamber provided with a pressure fluid connection; a valve rod having an axis of displacement, being disposed in said housing and displaceable by an action of the proportionally acting solenoid; two valves, for selectively forming a fluid communication path with said pressure fluid chamber, each disposed in said valve housing and comprising a displacable valve member connected in fixed relation to and actuable simultaneously with displacement of said valve rod; a permanent magnet (9), having a predetermined position with respect to said valve rod, and being arranged in proximity to said valve rod (20) in such orientation that a range of a displacement path of said permanent magnet (9) produced by a displacement of said valve rod lies within said pressure fluid chamber (10); and a magnetic field sensor (29), on said wall of said valve housing and disposed in a region of said pressure fluid chamber (10) for detecting a change of a field of said permanent magnet (9) as a displacement of said valve rod changes.
