Abstract
A ventilation system for a vehicle includes a distributor device for distributing ventilation air to different ventilation nozzles in the vehicle. The distributor device is provided with a cylindrical ventilator unit journal in a housing and provided with a casing surface and end walls in which there are disposed apertures for cooperation with outlets disposed in the circumferential surface and walls of the housing, whereby rotation of the ventilator unit makes possible regulation of the air flow to the different outlets.
Claims19
A ventilation distributor device for a vehicle ventilation system for distributing ventilation to a plurality of ventilator nozzles in the vehicle, the distributor device comprising:
- a substantially cylindrical housing having a first circumferential housing surface and a first housing end wall;
- at least one first outlet in the first circumferential surface and at least one second outlet in the first end wall;
- a substantially cylindrical ventilator unit rotatably journaled in the housing to rotate with respect to the housing, the ventilator unit having a second circumferential ventilator unit surface and a second ventilator unit end wall;
- at least one first aperture in the second circumferential surface and placed so that rotation of the ventilator unit may bring one first aperture of the ventilator unit to coincide with one first outlet from the housing;
- at least one second aperture in the second end wall placed so that rotation of the ventilator unit in the housing may bring one second aperture to coincide with one second outlet from the housing;
- at least one ventilator unit first aperture and one ventilator unit second aperture being merged to define a single continuous aperture;
- at least a first one of the first housing outlets and at least a first one of the second housing outlets together communicating with both of the second circumferential surface and the second end wall for being supplied with air via the single continuous aperture. PG,16
The device of claim 9, wherein at least one of the first apertures is circumferentially offset from other ones thereof in the second cylindrical surface.
