A pneumatic device (1) has at least one venting path (10) for venting the pneumatic device (1) in an outflow direction (R1). The venting path (10) includes a first volume (12), through which a flow can pass, a first compressed-air passage (14), and a sealing mechanism (18). The first compressed-air passage (14) pneumatically connects the first volume (12) to a pressurized part (16) of the pneumatic device (1). The sealing mechanism (18) changes between a normal state (Z1) and a sealing state (Z2). In the normal state (Z1) a flow can pass through the first compressed-air passage (14) both in the outflow direction (R1) and in an oppositely directed inflow direction (R2). In the sealing state (Z2) a flow can pass through the first compressed-air passage (14) only in the outflow direction (R1).
