<p>A valve system for controlling the water supply to at least one discharge line comprises a housing having an inlet passage, with at least one discharge passage spaced from the inlet passage and with both passages connecting into a flow control chamber. A closure member is movable in the flow control chamber and it has respective opposite closing surfaces adjacent the respective ends thereof and it is guided in the housing control chamber by a guide ring. The guide ring has an annular seat surface at each end which are cooperable with the respective closing surfaces. A tubular screen is arranged coaxially with and surrounds a portion of the control member, and when the closure surfaces are moved off the valve seats, the flow from the inlet around a closure member and through the screen to an electromagnetic valve flow passage may be carried out. Flow through the electromagnetic valve flow passage is controlled by an electrically operated valve. The flow control chamber opens upwardly in the housing and it is closed by a threaded screw cap which in turn has a central threaded bore which receives a set screw. Both the screw cap and the set screw are coaxially arranged with respect to the tubular screen and the closure member and the set screw may be adjusted axially to bear against the closure member in an end position.</p> |
