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.
Claims12
A valve device comprising a valve tappet (18) that effects a controlled opening or blocking of a fluid flow channel (16) in an engaged position on a valve seat (22), which is movable from a starting position into the engagement position in response to pressure loading with a pressure fluid, wherein pressure fluid drawn from the fluid flow channel is conveyed by electromagnetically driven pumping means (24) into a pressure chamber (44) assigned to the valve tappet in such manner that the pressurization for driving the valve tappet is achieved through multiple pump strokes of the pumping means that comprise a delivery piston (26).
