Abstract
A pneumatic supply device for an agricultural tractor includes a compressed air source for producing a compressed air flow, a cooler for cooling the air flow produced, and a first air dryer, which is fed with the cooled air flow and via the outlet of which a first pneumatic consumer group can be supplied with dehumidified compressed air in accordance with a first dehumidification and flow capacity, and a second air dryer, which is fed with the cooled air flow and via the outlet of which a second pneumatic consumer group can be supplied with dehumidified compressed air in accordance with a second dehumidification and flow capacity.
Claims6
A pneumatic supply device for an agricultural tractor, comprising:
- a compressed air source for producing a compressed air flow;
- a cooler for producing a cooled air flow;
- a first air dryer, which is fed with the cooled air flow, supplies a first pneumatic consumer group with dehumidified compressed air via a first dryer outlet in accordance with a first dehumidification and flow capacity;
- and
- a second air dryer, which is fed with the cooled air flow, supplies a second pneumatic consumer group with dehumidified compressed air via a second dryer outlet in accordance with a second dehumidification and another flow capacity;
- wherein the second pneumatic consumer group is supplied with the cooled air flow via an upstream pressure switching valve, wherein, when a predetermined supply pressure is undershot, the pressure switching valve adopts a closed position, with the result that the cooled air flow is available exclusively to the first pneumatic consumer group.
