The present invention relates to a valve assembly whose first valve accommodating member is conformed to the inside diameter of a second valve accommodating member in such a fashion that the first valve accommodating member is inserted without clearance so far into the second valve accommodating member that the first valve closure member is supported either on a bore step of a second pressure fluid passage or on the first valve accommodating member.

Valve mechanism, especially for anti-skid automotive brake systems

The present invention relates to a pressure control valve including a valve housing which houses a valve seat in a housing opening, a valve closure member which is movable into abutment on the valve seat and adapted to interconnect or isolate pressure fluid channels connected to the valve seat, a bore in a guide element for the accommodation of the valve closure member which is axially movably supported on the wall of the valve housing. The valve closure member is attached in the guide element by way of a simplified press fit in conformity with the demands of automation. The assembly of the valve coil is simplified in addition.

Pressure control valve

The present invention relates to an electromagnetic valve which includes a valve tappet that is axially movably arranged in a valve housing and fastened to a magnetic armature, and a valve piston axially movable in the valve housing, a diaphragm-type pressure fluid passage in the valve piston that is closed or opened by the valve tappet, another unthrottled pressure fluid passage arranged between the valve piston and the valve housing that is closed or opened by the valve piston, pressure fluid channels which open into the valve housing on either side of the valve piston, with both pressure fluid passages closed in the initial position of the electromagnetic valve. The valve piston will open the other, unthrottled pressure fluid passage only if, on the one hand, the hydraulic pressure acting on the valve piston in the valve closing direction is lower than the pressure of a spring fitted to the valve piston and active in the valve opening direction, and if, on the other hand, the pressure fluid passage in the valve piston is opened by the electromagnetic energization of the valve by means of the valve tappet.
