Pressure control valve for the open-loop or closed-loop control of a pressure of a fluid in a pilot pressure chamber, and vibration damper having such a pressure control valve

A pressure control valve for the open-loop or closed-loop control of a pressure of a fluid in a pilot pressure chamber, comprising:

• a valve housing with at least one inlet, which is fluidically connectable to the pilot pressure chamber, and with at least one outlet, and, between the at least one inlet and at least one outlet a first valve seat and a second valve seat which are arranged in a pilot valve chamber,
• a tappet with a pilot seal wherein the tappet is movable along a longitudinal axis by an energizable actuating device,
• wherein the pilot seal has a sealing portion with a first sealing face and a second sealing face which are arranged on opposite sides along the longitudinal axis,
• wherein, in an unactuated state of the actuating device by a restoring spring the pilot seal is arranged in a first position in which the first sealing face bears sealingly against the first valve seat and closes a first through-channel,
• wherein, in the actuated state of the actuating device the pilot seal can be arranged in a second position in which the second sealing face bears against the second valve seat and closes the second through-channel,
• wherein the pilot seal has a stop portion that is spring-mounted with respect to the sealing portion and which can come to bear against a stop between the first end position of a second end position before the second end position is reached.
