The invention relates to a pneumatic port, in particular an exhaust port for a bellows servo valve of an air spring device, a suspension system and a commercial vehicle. A pneumatic port (100) is an exhaust port for use in a bellows servo valve (200) of a suspension system (300), comprising: a port body (102) having a through opening (104); a valve body (110) arranged inside the through opening and having a piston (112) configured to actuate against a spring element (114) to control a flow path (116) through the through opening; and a gasket unit (120) arranged at the through opening and comprising a passage (122) for enabling an air flow through the gasket unit. A gasket unit is connected to the port body using a connecting element. In the pneumatic port, the connecting element is a cooperating thread (126, 128) arranged at the port body and at the shim unit, thereby reducing noise generated as air flows through the pneumatic port.
本发明涉及一种气动端口、特别是用于空气弹簧装置的波纹管伺服阀的排气端口、悬架系统和商用车辆。气动端口(100)是在悬架系统(300)的波纹管伺服阀(200)中使用的排气端口,包括:具有贯通开口(104)的端口主体(102);阀主体(110),其布置在所述贯通开口内部并且具有活塞(112),所述活塞被构造成抵靠弹簧元件(114)致动以控制通过所述贯通开口的流动路径(116);以及垫片单元(120),其布置在所述贯通开口处并且包括用于使空气流能够通过所述垫片单元的通路(122)。垫片单元使用连接元件连接到所述端口主体。在气动端口中,连接元件是布置在端口主体处和垫片单元处的协作螺纹(126、128),从而减少空气流过所述气动端口时产生的噪声。
