Abstract
A switching valve, in particular for controlling a fluid subject to high pressure is described. The switching valve has at least one valve unit, which includes a valve seat element and a switching element guided movably in a guide element, wherein the valve seat element and the switching element interact to provide a switching valve function. The valve seat element and the guide element are provided in a housing. The valve seat element, the guide element and the housing form a through flow channel for the fluid to be controlled. An elastically and/or plastically deformable sealing body is provided in a fully enclosed space between the inner wall of the housing and the outer walls of the valve seat element and of the guide element. The sealing body can be subject to a predetermined pressure to seal off the through flow channel from the housing and subject the valve seat element and the guide element to an inward-directed preload.
