Abstract
A valve device, comprising a valve tappet (18), which causes a controlled opening or blocking of a fluid flow channel (16) in an engagement position on a valve seat (22) and which can be brought from a starting position to the engagement position as a reaction to an application of pressure by means of a pressure fluid, wherein the pressure fluid is conveyed by electromagnetically driven pumping element (24) into a pressure chamber (44) associated with the valve tappet in such a way that the application of pressure for driving the valve tappet is accomplished by a plurality of pumping strokes of the pumping element, which has a conveying piston (26), in particular a reciprocating piston.
