Arrangement for a utility vehicle
An arrangement for a utility vehicle includes at least one air dryer unit and a regulating unit, wherein the air dryer unit and the regulating unit are designed in each case as separate units. The air dryer unit has at least one air dryer module, in particular an air dryer cartridge, at least one discharge valve and at least one control line for the pneumatic control of the discharge valve. At least one connecting line is provided in the air dryer unit with connection to the air dryer module. The connecting line leads directly to a consumer non-return valve for the air dryer unit, which is arranged outside of the air dryer unit, wherein the connecting line can be used at least partially bi-directionally and/or can be or is connected to a bi-directionally usable line section.
1. An arrangement for a utility vehicle, comprising:
at least one air dryer unit;
a regulating unit, wherein
the air dryer unit and the regulating unit are each configured as separate units,
the air dryer unit has at least one air dryer module, at least one discharge valve and at least one control line for pneumatically controlling the discharge valve,
in the air dryer unit, following the air dryer module, at least one connecting line leads directly to a consumer non-return valve for the air dryer unit, which is located outside the air dryer unit, and
the connecting line is at least partially bi-directionally usable and/or is connectable or connected to a bi-directionally usable line section.
2. The arrangement as claimed in claim 1 , wherein
the control line additionally serves for pneumatically controlling a compressor.
3. The arrangement as claimed in claim 1 , wherein
the connecting line is a connecting line without any pneumatic elements.
4. The arrangement as claimed in claim 1 , wherein
the connecting line is unthrottled and/or does not have a throttle element.
5. The arrangement as claimed in claim 1 , wherein
the connecting line leads to a system boundary of the air dryer unit and is connectable at the system boundary to a further line or, in the installed state of the arrangement, is connected to a further line.
6. The arrangement as claimed in claim 1 , wherein
the consumer non-return valve, which is coupleable or coupled to the connecting line, is arranged in the regulating unit.
7. The arrangement as claimed in claim 6 , wherein
in the regulating unit, a further additional non-return valve is coupleable or coupled to the connecting line, wherein the additional non-return valve enables a flow to pass through the connecting line in a direction which is contrary to a permitted flow direction of the consumer non-return valve.
8. The arrangement as claimed in claim 1 , wherein
the connecting line is connectable to a line or, in the installed state of the arrangement, is connected to a line, in which a further additional non-return valve is provided, and
the line is coupleable or coupled to the connecting line, wherein the further additional non-return valve enables a flow to pass through the connecting line in a direction which is contrary to the permitted flow direction of the consumer non-return valve.
9. The arrangement as claimed in claim 1 , wherein
the connecting line and the control line are designed as adapters and/or in that a control line is integrated and/or guided in the connecting line.
10. The arrangement as claimed in claim 1 , wherein
the air dryer unit has at least one heater.
11. The arrangement as claimed in claim 1 , wherein
the regulating unit has a multi-circuit protection valve.
12. The arrangement as claimed in claim 1 , wherein
the regulating unit has a regeneration device for regeneration of the air dryer unit.
13. The arrangement as claimed in claim 1 , wherein
the air dryer module is an air dryer cartridge.
