Embodiment Construction

[0030] exist figure 1 The air handling unit 1 shown in the Figure 4 Used in the compressed air system 2 of the vehicle. The air treatment unit 1 has a compressed air input 4a for connection to a compressor 3 and a compressed air output 4b for connection to a multi-circuit protection valve 5, a plurality of consumer circuits 6a, 6b, 6c, 6d as Consumer devices are connected to the multi-circuit protection valve, the consumer circuits each having, for example, a compressed air storage container for temporarily storing the supplied compressed air. The compressor 3 runs on the motor shaft 8 and has a pneumatic control input 3 a by means of which the delivery operation of the compressor can be terminated when pressure is applied and thus an idling operation is present.

[0031]Furthermore, the compressor 3 can be switched between delivery operation and rest operation of the compressor 3 via the first electrical control signal S 1 of the control device 7 ; according to the inventi...

Abstract

An air treatment unit for an automotive compressed air system is provided with the following components: a compressed air input end (4a) which is connected with a compressor; a dryer unit (10) which has a dryer input end (10a) that is connected with a compressed air input end; a conveying check valve (12) which is configured behind the dryer unit in a conveying direction and separates a conveying area (14) from a subsequent system area (15); an exhausting valve (16) which is used for exhausting the dryer input end and is provided with a pneumatic control input end (16a) and can be switched between a shutoff position of the conveying period and a passing position of a regenerating period; a regenerating valve (18) which is shut off in the conveying period and connects the system area with a first regenerating path (20) of a first regenerating throttle plate (23); and a regenerating area (19) which is constructed between the regenerating valve and the pneumatic control input end of the exhaust valve. A following state can be adjusted in the regenerating area, wherein the exhaust valve is open when the regenerating valve is shut off.

Description

technical field [0001] A compressed air system of a vehicle, in particular a commercial vehicle, usually has a compressor, an air treatment unit connected to the compressor, and one or more consumer circuits connected to the air treatment unit. The air treatment unit is used to dry and optionally filter the supplied air by means of the dryer unit and to set the different work phases. In the delivery phase, the air delivered by the compressor is dried by the dryer unit and passed on to the consumer circuit. Accordingly, moisture accumulates in the dryer unit accordingly, which is again conducted in the regeneration phase counter to the conveying direction and discharged via the compressed air outlet. Furthermore, idling phases or sleep phases in which the compressor is not operated and possibly other phases can be adjusted. Background technique [0002] Air handling units usually have various valves that are tuned out for different stages. In particular the compressor cont...
