Abstract
A pneumatic actuating element, an exhaust air system, a housing, and a pneumatic actuator, are provided, which are designed to provide a possibility to collect exhaust air that is discharged when the pneumatic actuating element is ventilated, which exhaust air typically includes contaminations, and to release the exhaust air in an area that is not visible during operation, in order to prevent irritation due to a contaminated housing on the one hand and, on the other hand, to protect components that might come into contact with the contaminated exhaust air.
Claims9
A pneumatic actuator, comprising:
- at least one pneumatic actuating element which is configured to influence a required working pressure starting from a pressure of a compressed air supply that is connectable to the pneumatic actuating element, wherein
- the pneumatic actuating element is connected to an exhaust air line of an exhaust air system in order to emit exhaust air, that is discharged from the actuating element to reduce the working pressure, to the exhaust air line, wherein the exhaust air line is in fluid communication with atmosphere;
- a housing;
- at least one pneumatic operating element which is configured to be loaded with the working pressure by the pneumatic actuating element and vented again by the pneumatic actuating element, wherein
- the at least one pneumatic actuating element, the exhaust air system, or the at least one pneumatic operating element, is arranged inside the housing, and
- the at least one pneumatic operating element is configured to operate selection elements of a gearbox.
