Patent ID: 7172171

Claim:
A controllable solenoid valve, comprising: a valve housing; a first sealing seat in the valve housing; a slide which is displaceable in the valve housing in an axial direction of the housing between first and second final positions; a first sealing body which is seatable in the first sealing seat and is engageable by the slide to be displaceable in the axial direction with the slide; a cylindrical housing which surrounds the first sealing body and the first sealing seat; radial throughpassages in the cylindrical housing; a spring acting upon the slide counter to the magnetic force to maintain the slide in one of the final positions when the electromagnet is not sufficiently energized to drive the slide with force sufficient to completely overcome force of the spring; and a solenoid comprising an electromagnet, the solenoid being operatively connected to the slide so that sufficient electrical energization of the solenoid to produce a magnetic force sufficient to completely overcome force of the spring displaces the slide from one of the final positions to the other of the final positions; wherein the radial throughpassages are open when the slide is in the first final position and are closed when the slide is in the second final position or in an immediate vicinity thereof.
