Claim 13:
14. A device for open-loop and closed-loop control of a pressure in a pilot pressure chamber (12), comprising
a primary circuit (14) for a compressed fluid,
a working machine (16) arranged in the primary circuit (14) for conveying the compressed fluid in the primary circuit (14) along a conveying direction,
a hydraulic or pneumatic slider (24),
a secondary circuit (20) for the compressed fluid,
which starts at a branch (18) of the primary circuit (14), which branch is arranged downstream of the working machine (16) with respect to the conveying direction, and
which flows back into the primary circuit (14) at a junction (22),

a pilot pressure chamber (12) arranged in the secondary circuit (20), and
a pressure control valve (30) according to claim 1, arranged between the pilot pressure chamber (12) and the junction (22) in the secondary circuit (20), wherein
the slider (24) is arranged and designed so that the slider (24) can block or unblock the flow of the compressed fluid in the primary circuit (14) between the branch (18) and the junction (22) depending on the pressure in the pilot pressure chamber (12).
