Pressure control valve and device comprising such a pressure control valve, for open-loop or closed-loop control of the pressure of a pressurized fluid in a pilot pressure chamber

A pressure control valve (30) for open-loop or closed-loop control of a pressure of a compressed fluid in a pilot pressure chamber (12), comprising

• a valve housing (50) with at least one inlet (41), which can be fluidically connected to the pilot pressure chamber (12), and at least one outlet (43),
• a wall section (51) which is permanently arranged in the pressure control valve (30) and which
• has a passage channel (60) through which the compressed fluid can flow, and
• forms a first valve seat (58),
• a tappet (52), which is mounted in the valve housing (50) so as to be movable along a longitudinal axis (L) by means of an actuation device (49) that can be energized,
• a first sealing element (54), which
• forms a second valve seat (66),
• is mounted in the valve housing (50) so as to be movable along the longitudinal axis (L) and
• is biased by means of a first spring (56) against the actuation direction (B) of the actuation device (53) into a closure position in which the first sealing element (54) bears against the first valve seat (58) and can be moved by the compressed fluid in the actuation direction (B),
• a second sealing element (64), which is secured to the tappet (52) and, by energizing the actuation device (53), can be moved by means of the tappet (52) along the longitudinal axis (L) between a first position, in which the second sealing element (64) bears against the wall section (51) and closes the passage channel (60), and a second position, in which the second sealing element (64) bears against the second valve seat (66), the second valve seat (66) being arranged axially offset to the first valve seat (58) with respect to the longitudinal axis (L), and
• a second spring (68), which biases the second sealing element (64) into the first position.
