The invention relates to a device and a method for preventing the penetration of a liquid (F) into a pressure guiding portion (16) of a pneumatic device (1). The pneumatic device (1) according to the invention has at least one venting path (10) for venting the pneumatic device (1) in an outflow direction (R1), the venting path (10) comprising a first volume (12) through which it can flow, a first compressed air channel (14) and a sealing device (18). A first compressed air channel (14) pneumatically connects the first volume (12) to a pressure guide section (16) of the pneumatic device (1). The sealing device (18) is designed to switch at least between a normal state (Z1) and a sealed state (Z2). In a normal state (Z1) of the sealing device (18), the first compressed air channel (14) can flow through in an outflow direction (R1) and in an oppositely directed inflow direction (R2). In the sealing state (Z2) of the sealing device (18), the first compressed air channel (14) can flow through only in the outflow direction (R1).

    本发明涉及防止液体(F)渗入到气动设备(1)的压力引导部分(16)中的设备和方法。根据本发明的气动设备(1)具有用于沿流出方向(R1)使气动设备(1)排气的至少一个排气路径(10),其中,排气路径(10)包括可被穿流过的第一体积(12)、第一压缩空气通路(14)和密封装置(18)。第一压缩空气通路(14)将第一体积(12)与气动设备(1)的压力引导区段(16)气动连接起来。密封装置(18)被设计成用于,至少在正常状态(Z1)与密封状态(Z2)之间切换。在密封装置(18)的正常状态(Z1)中,第一压缩空气通路(14)在流出方向(R1)上和在相反指向的流入方向(R2)上能被穿流过。在密封装置(18)的密封状态(Z2)中,第一压缩空气通路(14)仅在流出方向(R1)上能被穿流过。
