The invention relates to a ventilation cap (11.1, 11.2) on a solenoid valve (1) in compressed-air installations, for example for vehicles, having a sealing element (12) which is arranged on a carrier element (18), wherein the carrier element (18) is arranged at an axial end (10a) of an outlet pipe (10) of the solenoid valve (1), and the sealing element (12) is arranged in the region of the axial end (10a) of the outlet pipe (10). For quiet ventilation and for protection against an ingress of water, it is provided that the sealing element (12) is formed as a cap which engages radially and axially over the carrier element (18) and which has a coaxially extending circular flange (13), that the flange has, at the inner side (14) thereof adjacent to the free axial end thereof, at least one receptacle (15) for at least one radially outwardly protruding snap-action contour (19) of complementary form on the carrier element (18), that the carrier element has a coaxially arranged hollow cylindrical projection (20), that said projection (20) is fastenable to the axial end (10a) of the outlet pipe (10), and that the carrier element (18) has, centrally, a coaxial ventilation path (21) which is connected in terms of flow to at least one outlet opening (26) via a labyrinthine sealing structure (25).
本发明涉及一种例如用于车辆的压缩空气机组中的电磁阀(1)上的排气帽(11.1、11.2),排气帽具有密封元件(12),密封元件布置在承载元件(18)上,其中,承载元件(18)布置在电磁阀(1)的出口管(10)的轴向端部(10a)上,并且密封元件(12)布置在出口管(10)的轴向端部(10a)的区域中。为了低噪排气以及为了防止水的侵入设置的是,密封元件(12)被构造为径向和轴向都与承载元件(18)搭接的帽,帽具有同轴延伸的圆形的边缘(13),该边缘在其相邻于其自由轴向端部的内侧(14)上具有至少一个容纳部(15),至少一个容纳部用于至少一个在几何上互补地构成的、在承载元件(18)上径向向外突出的扣合轮廓(19),承载元件具有同轴布置的空心柱体式的延伸部(20),该延伸部(20)能紧固在出口管(10)的轴向端部(10a)上,并且承载元件(18)在中央具有同轴的排气路径(21),排气路径经由迷宫式密封结构(25)在流动技术上与至少一个出流开口(26)连接。
