Embodiment Construction
[0084] Figure 1 to Figure 9 Each shows a compressed air preparation device in which compressed air is prepared for supplying the compressed air consumer circuit of the vehicle.
[0085] The same reference signs are used in the figures for identical or mutually corresponding elements.
[0086] Next, the common basic structure is explained first for all embodiments. The features of the exemplary embodiment represented by the individual figures are then explained with the aid of the individual figures.
[0087] These compressed air preparation devices each have a compressed air input 1 to which a compressor 2 can be connected. The pressure line 3 is connected to the compressed air input 1 . The system pressure line 5 is connected to the pressure line 3 via a check valve 4 . Multi-circuit protection valve 6 (see Figure 10) can connect the system pressure pipeline 5. Several individual compressed air consumer circuits 7 , 8 , 9 , 10 , for example compressed air brake circui...

The present invention relates to a compressed air preparation device, a compressed air supply system and a preparation module and a method for operating a compressed air preparation device, a control module, and a vehicle. The compressed air preparation device (30) has a compressed air input terminal (1), the compressor (2) may be connected to the compressed air input terminal. The pressure line (3) is connected to the compressed air input (1) and the system pressure line (5) is connected to the pressure line (3) by means of a check valve (4). A drying device is arranged in the pressure line (3). The switching position dependent on the exhaust control valve (23) may be connected to the system pressure line (5) the regeneration path (22) between the drying unit (11) and the check valve (4) into the pressure line (3). The feed of compressed air to the compressed air input terminal (1) can be controlled with an electrically maneuverable feed control valve (17). In order to make a diversified and efficient preparation of compressed air at a small cost possible, according to the present invention: the passability of the regeneration path (22) is closely related to the position of the feed control valve (17) and the position of the exhaust control valve (23).
Description
technical field [0001] The invention relates to a compressed air preparation device, a compressed air supply system for a vehicle and a preparation module for a compressed air preparation device or a compressed air supply system. The invention also relates to a method and a control module and a vehicle for operating a compressed air preparation device. Background technique [0002] EP1318936B1 discloses a vehicle compressed air brake system with a compressed air preparation device, the pressure line of which can be fed with compressed air by a compressor. The system pressure line is connected to the pressure line through a check valve. A drying device is arranged in the pressure line, which cleans the compressed air fed by the compressor of vapor and particle loads. [0003] In push operation, the compressed air fed by the compressor is pushed through the drying device into the system pressure line and made available there for use in the compressed air consumer circuit. ...
