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.
