Embodiment Construction

[0022] according to figure 1 A compressed air system 1 of a vehicle, not further shown here, comprises a compressor 10 which pumps compressed air via an air dehumidification device 11 into a compressed air storage device 12 . In the basin-shaped storage device 13 in the lower part of the compressed air storage device 12 , liquid condensate collects there by condensation on the inner walls of the compressed air storage device 12 , for example in the event of saturation or malfunction of the air dehumidification device 11 . Underside of compressed air storage unit. On the underside of the basin-shaped storage device 13 is arranged a sensor unit 2 which, when sufficient moisture is detected, then emits a signal in order to cause an actuation of the drainage device 9 in order to remove the condensed liquid from the basin-shaped storage device. The device is discharged to the surrounding environment (not shown here) via a drainage system. This manipulation can be performed manual...

Abstract

The invention relates to a compressed air system (1) for controlling at least one pneumatic component of a motorized vehicle, comprising a sensor unit (2) for detecting condensation water, wherein the sensor unit (2) comprises at least one reversible geometrically expandable hygroscopic element (4) for absorbing the moisture, for working together with an electric expansion detection device (5), in order to detect and to signalize condensation water or moisture inside the compressed air system (1).

Description

technical field [0001] The invention relates to a compressed air system for actuating at least one pneumatic component of a motor-equipped vehicle, the compressed air system comprising a sensor unit for detecting condensation. [0002] The field of application of the invention extends to vehicles which have a compressed air system via which, for example, brakes or other pneumatically actuatable actuators can be actuated. Background technique [0003] In this case, the compressor draws in ambient air, compresses it and supplies the compressed air to various consumers. Since the ambient air may contain air humidity, in order to remove the humidity from the compressed air, a desiccant is usually provided on the output side of the compressor, which absorbs the humidity of the flow-through air. During the reduction phase, the possibly saturated desiccant is circulated in the opposite direction by the dried air in order to be dried itself. However, it can happen that the air dry...
