A pressure-limiting valve includes a housing having a piston, a pressure-limiting adjusting spring, at least one inlet and at least one outlet. The piston can assume an open position in which the inlet and the outlet are connected to each other, and at least one closed position in which the inlet and the outlet are separated from each other. The piston has a first piston ring with a sealing surface and a second piston ring. In the closed position, the sealing surface is drawn against a housing projection in a sealing manner by a pneumatic force which acts on the second piston ring and is directed against the force of the pressure-limiting adjusting spring. A pneumatic passage in the piston which implements a safety valve function can be sealed by a spring-loaded safety valve body arranged on a side of the second piston ring that is opposite the outlet.
