  • Solenoid valve
    Patent number: 5996965
    Abstract: A solenoid valve especially intended for wet-room fittings. It has a housing with an intake and an outlet sealed off from each other and prevented from communicating while the valve is closed by a body that rests on a seat. The housing is essentially flower-pot shaped and has a threaded section at the open end positioned concentric and coaxial to the intake and outlet, which are in turn rotationally symmetric and face the open end such that the incoming flow is opposite the outgoing flow.
