Device for detecting compressed air, air treatment unit, motor vehicle therewith and method for detecting compressed air and producing a device for indicating compressed air
The invention relates to a device for displaying existing compressed air within a compressed air system. For this purpose, the device has a through hole 19 within a housing 21 of a component which is pressurized with compressed air, the through hole 19 being designed in such a way that the pressure present in the system within a predetermined pressure range is acoustically displayed as a throttle point. Furthermore, the device has a housing cover 22 for the pressure-tight closing of the through hole 19. In addition, the invention relates to an air treatment unit, a motor vehicle and a method for displaying existing compressed air and for producing such a device. The invention advantageously enables a secure exchange of individual compressed air system components, in particular pressure sensors and / or solenoid valves, within a compressed air system.
