Abstract: A valve device has a valve space (14) formed in a housing (12a, 12b), a valve drive (16) sealed against the valve space (14) by means of a sealing body (26) made of an elastic material, a two-armed actuating lever (32) which extends through the sealing body and whose first arm (34) is connected to the valve drive (16), and a closing body (28) molded on the sealing body (26), which forms a jacket of the second arm (30) of the actuating lever (32). The closing body (28) can cover or clear a valve seat (24) disposed in a valve space (14) by a swivel movement of the actuating lever (32), wherein the actuating lever (32) includes a spatially fixed bearing axis.

Abstract: A valve device includes a housing body having a fluidic chamber which has at least one valve seat and a valve control member. The member includes a rigid frame having first and second opposed surfaces and being shaped with recesses, at least one of the recesses extending between the surfaces, a rigid actuating member and a flexible diaphragm on the first surface which is connected with the frame and actuating member by injection molding. The recesses are filled with, and sealing contours on the second surface are formed of, the diaphragm material. At least one valve body is formed by a section of the actuating member and a section of the diaphragm surrounding the actuating member. The valve control member is joined with the housing body so that the diaphragm closes and seals the fluidic chamber and the valve body is opposite the valve seat.

Abstract: The invention relates to a valve device including a housing body (12) having a fluidic chamber (14) formed therein which has at least one valve seat (22), and a valve control member (16) produced in one piece by a molding technique to include a rigid frame (24) and a flexible diaphragm (28) with at least one valve body (34) integrated therein. The valve control member (16) is placed on the housing body (12), its diaphragm (28) tightly sealing the fluidic chamber (14) thereof, and with its valve body (34) located opposite the valve seat (22). Furthermore, a method of manufacturing a valve control member (16) for a valve device is disclosed.

Abstract: A magnetic drive for a valve, in particular for a pneumatic or hydraulic valve, includes a movable armature (14) and a permanent magnet (20). The permanent magnet (20) is formed from a magnetic paste or a magnetic foil. In preferred embodiments, the permanent magnet (20) is integrated into the movable armature (14) and cooperates with a fixed solenoid.
