Embodiment Construction

[0028] The same reference numbers are used below to identify the same or similar parts.

[0029] figure 1 A schematic diagram showing a first embodiment of a compressed air treatment device. The compressed air treatment plant 10 shown includes a compressed air input 42 and another compressed air input 44, through which in particular untreated compressed air can be supplied to the compressed air treatment plant 10. For this purpose, the compressed air input 42 may be connected to a compressor not shown, which sucks and compresses the surrounding air. The other compressed air input 44 may be used to selectively deliver compressed air from other compressed air sources not shown, for example. The compressed air input through the two compressed air input ports 42 and 44 can be delivered to the air drying cylinder 30 through the compressed air delivery pipeline 34. The air drying cylinder 30 may include a filtering device that separates oil and dirt particles from the compressed air ...

Abstract

The invention relates to a compressed air processing system (10) for a vehicle, in particular a commercial vehicle, which comprises a compressor control output (12), a solenoid valve device (16) which can be actuated by an electronic control device (14) of the compressed air processing system (10), and a pneumatically actuatable valve device (18). A control pressure can be applied to the compressor control output (12) using the pneumatically actuatable valve device (18) and the pneumatically actuatable valve device can be actuated (18) using the solenoid valve device (16) and from a central compressed air region (20). The present invention also relates to a method for operating the compressed air processing system.

Description

Technical field [0001] The invention relates to a compressed air processing equipment for vehicles, especially commercial vehicles. [0002] The invention also relates to a method for operating a compressed air treatment device for a vehicle, especially a commercial vehicle. Background technique [0003] Modern commercial vehicles have many subsystems that operate with compressed air. For example, in commercial vehicles, brake systems, transmissions and air suspensions can be operated with compressed air. The compressed air required for this can be produced by means of a compressor integrated into the vehicle, where the compressed air produced by the compressor can be cleaned of dirt and moisture in the compressed air treatment equipment, thereby avoiding the use of the supplied compressed air operating components Of wear. Compressed air treatment systems designed for this purpose can usually be controlled electronically by an associated controller. Based on the control or regu...
