Abstract
A pressure control valve for controlling or regulating a pressure of a compressed fluid in a pilot pressure chamber includes a valve housing with at least one inlet which is fluidically connectable to the pilot pressure chamber, at least one outlet, a tappet mounted in the valve housing to be moved along a longitudinal axis by means of an actuation device that can be energized, and a first seal element which is mounted in the valve housing to move along the longitudinal axis and which is preloaded into a closed position by means of a first spring. The first seal element rests against a first valve seat in the closed position. The first seal element has a passage through which the compressed fluid can flow. A second seal element is secured to the tappet and can be moved by the energization of the actuation device.
