    摘要： The invention relates to an air treatment system for the supply of compressed air in utility motor vehicles, having a plurality of compressed-air circuits connected to a main supply line (102), wherein a trailer and/or parking brake supply line (110) is connected to a supply line (108) of one or more other compressed-air circuits, and wherein, in the trailer and/or parking brake supply line (110), there is provided a valve arrangement (112) which automatically opens at a predefined supply pressure and which can additionally be pneumatically pilot-controlled into an open position. In said air treatment system, it is also provided that the valve arrangement (112) has a directional valve (114, 114'), which is open in a first valve position and which, in a second valve position, forms a check valve, said check valve opening in the direction of a trailer and/or parking brake supply port (23, 25) and being loaded in a closing direction by a preload spring (32), and has a flow transfer valve (OV23), which is positioned downstream of the directional valve (114, 114') and which opens at a predefined opening pressure.

    摘要： The invention relates to a method for operating a pneumatic system of a vehicle, said pneumatic system comprising an electronically and/or pneumatically controlled compressor which delivers compressed air as required during a normal mode in order to feed the pneumatic system and which is switched off or idles outside the delivery phases. In said method, an ambient temperature (T_Umg) around the pneumatic system is continuously sensed and is compared with a predefined target temperature (T_Ziel), a freezing risk is identified when the ambient temperature (T_Umg) reaches or drops below the target temperature (T_Ziel), and when a freezing risk has been identified, a cold mode is activated in which the compressor delivers compressed air also outside the required expected delivery phases of the normal mode, and said additional compressed air is supplied to pneumatic system components that risk freezing in order to heat same and is then additionally made available to the pneumatic system or is discharged into the environment. In order for the method to conserve energy and inexpensively and reliably prevent pneumatic system components from icing up, an additional ON time (ED_zus) of the compressor in the cold mode is variably controlled at least in a predefined ambient temperature range and is determined in accordance with the difference in temperature (ΔΤ) between the ambient temperature (T_Umg) and the target temperature (T_Ziel).

    摘要： The invention relates to a compressed air control device (2) and to a compressed air control method for controlling respective operating states of a compressor (6) and of an air drying device (8) in a vehicle. The compressed air control device (2) has a compressor control outlet (36), by means of which the compressed air control device can be pneumatically connected to a control inlet of the compressor (6) in order to pneumatically switch the operating state of the compressor (6). The compressed air control device (2) further comprises a system pressure inlet (28), by means of which the compressed air control device can be pneumatically connected to a system pressure line (21), which conducts a system pressure produced by the compressor (6). The compressed air control device (2) further comprises a ventilation control outlet (36), by means of which the compressed air control device can be pneumatically connected to a control inlet of the air drying device (8) in order to pneumatically switch the operating state of the air drying device (8). Finally, the compressed air control device (2) also comprises a pneumatically operable ventilation control valve (14), by means of which the system pressure inlet (21) can be pneumatically connected to the ventilation control outlet (36) depending on the system pressure in order to switch

    摘要： The invention relates to a compressor cylinder head with a cylinder head housing (6), having at least one pressure valve (18) with an associated pressure valve channel (17) in the cylinder head housing (6), wherein the pressure valve channel (17) connects a compression chamber (8) arranged below the compressor cylinder head to a pressure chamber (16) inside the compressor cylinder head. Further, the compressor cylinder head has one or more channel portions with a first coolant channel system (24) inside the cylinder head housing (6), which can be filled with a coolant that flows around the pressure chamber (16). By means of a casting method, the cylinder head housing (6) is produced integrally with the first coolant channel system (24) arranged therein, and further coolant channels (34) are arranged on either side of the at least one pressure valve channel (17). Each of the further coolant channels (34) are connected at least at two points to the first coolant channel system (24). The invention further relates to a motor vehicle with a compressor for producing compressed air by means of the compressor cylinder head according to the invention, and a method for cooling and producing such a compressor cylinder head.
