Abstract
The present teachings relate to an air feed device with at least one impeller, with at least one housing that at least partially surrounds the impeller, with at least one intake opening for inward suction of air into an operating space of the impeller, with at least one opening to blow out air from the operating space of impeller. Provision is made that the air feed device has at least one additional through-passage opening for air.
Claims19
An air feed device comprising:
- a. at least one impeller,
- b. at least one impeller housing that at least partially surrounds the at least one impeller,
- c. at least one suction intake opening for intake of air into an operating space of the at least one impeller,
- d. at least one blow-out opening for blowing of air out of the operating space of the at least one impeller, and
- e. a predistributor at least partially surrounding the at least one impeller housing and distributing the blown-out air from the at least one blow-out opening at least partially around the at least one impeller housing,
- wherein the predistributor has at least one through-passage opening for blowing air out of the air feed device, for intake of air into the air feed device, or both, and
- wherein a seat comprises the air feed device.
