PNEUMATIC DEVICE WITH SEALING MEANS AND METHOD THEREFOR

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