Abstract: Valve arrangement for spray damping units of printing machines with at least one valve for controlling a flow of liquid, in which the valve includes a housing with an inlet and outlet, into which a valve body arrangement is inserted with the help of a fast-action closure.

Abstract: A solenoid valve, particularly for hot water, has a diaphragm that is disposed with no folds that accumulate air or vapor bubbles. The diaphragm extends in a smooth curve between its outer edge and its inner edge so that the bubbles are directed to the level where the mouth of the inlet conduit enters the valve chamber. Preferably the center axis of the valve chamber and a solenoid system is tipped back to form an obtuse angle with the center axis of the inlet conduit. In addition, the inlet conduit has a portion of the upper inside wall that slopes upwardly in the direction away form the valve chamber and toward the inlet. In this portion, a discharge channel, such as a groove, extends in the direction from the valve chamber to the inlet. The discharge channel helps direct accumulated air and vapor bubbles from the valve chamber out toward the inlet.

Abstract: A fluid control servo-solenoid valve with self-contained actuating fluid includes a housing configured as a small, elongate body having a pair of lengthwise sides and a pair of widthwise sides each relatively shorter than either of the lengthwise sides, whereby the valve inlet and the valve outlet are each disposed on a respective one of the widthwise outer sides of the housing and the inlet/outlet flow direction extends parallel to the housing longitudinal axis. The fluid control servo-solenoid valve with self-contained actuating fluid also includes a differential piston disposed in the housing such that its movement is perpendicular to the housing longitudinal axis. The pilot valve of the fluid control servo-solenoid valve with self-contained actuating fluid is dismountably secured on the respective smaller outer side of the housing on which the valve outlet is located.

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.

Abstract: A servo valve controlled by a bistable solenoid valve and activated by the same fluid--liquid or gas--it controls the flow of. A disk is mounted on a differential piston that travels back and forth in the housing. A compression chamber at one end of the piston communicates with a fluid intake and, by way of a seat facing the disk, with a fluid outlet. The piston has an eccentric control bore extending through it. A control chamber at the other end of the piston communicates with the fluid outlet through a depressurization channel and with the compression chamber through the control bore. The solenoid valve has a chamber and seat and an armature that travels back and forth in a tube. The tube extends through a coil on the housing. A gasket is mounted on the end of the armature facing the solenoid valve's seat. The other end faces a head accommodated in the tube. A yoke surrounds both ends of the coil. The depressurization channel extends through the chamber and seat and can be closed off by the plug.

Abstract: A solenoid valve, especially an outlet valve for infusion water. A valve chamber (2) is accommodated in a valve housing (1) and communicates with a supply channel (Z) and with a drain channel (A) by way of a valve seat (3). The magnetic armature (6) of a magnetic system accommodated on valve housing (1) is connected to a valve plate (10) accommodated in the valve chamber (2) opposite the valve seat (3). The valve chamber (2) is sealed off from the interior (11) of the magnetic system by an isolating diaphragm (12). To prevent calcium deposits, the valve seat (3) has a sheet (13) of polytetrafluoroethylene accommodated coaxially along its inner circumference and projecting beyond the surface of the valve seat (3) on the side facing the valve plate (10). The upper edge of the sheet (13) facing the valve plate (10) is in sealing plane with respect to the valve plate.

Abstract: A valve controlled by the same medium it handles and released by a preferably electromagnetically activated control valve. Contaminants in the medium that clog up the control bore in servocontrolled valves that employ a differential piston, a relief bore that can be closed off with a control valve, and a control bore that connect a pressure connection with a control space prevent the valve from closing. A mechanism that is especially simple in design is proposed to constantly keep the control bore clean during operation. The control space accommodates a wire spring that rest against the differential piston and against the valve housing and extends through the control bore. The motion of the piston is accompanied by a relative motion between the control bore and the spring that results in a constant cleaning action. The valve is especially practical in water lines and has the advantage of constant self-cleaning on the part of the control bore.
