Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1 . 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. 2 . The pneumatic supply device of claim 1 , wherein the cooled air flow is divided and fed in parallel to the first and the second air dryers. 3 . The pneumatic supply device of claim 1 , wherein the cooled air flow is first of all passed through the second air dryer and then divided in order to supply the second pneumatic consumer group and the first air dryer. 4 . 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 air 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 air 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. 5 . The agricultural tractor of claim 4 , wherein the cooled air flow is divided and fed in parallel to the first and the second air dryers. 6 . The agricultural tractor of claim 4 , wherein the cooled air flow is first of all passed through the second air dryer and then divided in order to supply the second pneumatic consumer group and the first air dryer.
