The roof of the driver's housing of a utility vehicle, for example a truck, is shown at 1. An air conditioning unit shown generally at 2 is on attached to the cableway 1. The unit 2 is in a suitable one opening in the roof 1, this opening is through Uinfangsdiclitungselemente 3, 4 limited.

The air conditioning arrangement Z is covered by a hood 5 with an outer, forwardly directed air vent 6. A condenser 7 is mounted inside the hood 6 near the inlet 6; behind the condenser 7 there is an air intake fan 8 which is driven by an electric motor.

The space in which the capacitor 7 is stored is through a thermally insulating partition wall 10 from a rear one Space C within the hood 5 separated. An evaporator is housed in room C and works with a centrifugal fan 12 together that is driven by its own electric motor to air conditioned over the coils of the Blow off the evaporator.

Y on the internal pool of Pahrzeugkabinendaohee 1 according to the above-mentioned opening is a Einrichtung13 according to the invention supported _s to distribute conditioned air; this has a shaped panel 14, which is provided with a circumferential loop 14a, which is fastened to the inner surface of the lamellae 1 by screws 15 »

The space A communicates with the interior of the driver's housing through four outlet openings, of which two, 24 "are arranged along the front edge of the panel 14" and the other two 24a (FIG. 2) are arranged along the side edges of the panel 14. The öffnung'24 _β 24a are rotatable with mungsleitelementen Strö "25 provided to respectively direct air streams which impinge through openings 24, 24a against the front and side glass window of the cabin.

Each of the rotatable flow guide elements 25 cooperates with the respective peripheral outlet opening of the panel and comprises, as shown in FIGS. 5 and 6, a substantially cylindrical body, oiler stamped from Kunstetoffmatsrial 1st and has two läagliche parallel walls 26, between

is when one looks along the longitudinal axis of the element 25.

The two longitudinal ends of each element 25 are cylindrical End portions 31 provided which are milled outside and a rotation of the element 25 around its Aohse by means of a single finger to make it easier to adjust the direction of the air flow through the channel 2 7 transversely to the longitudinal axis of the element 25.

Each element 25 is on the opposite ends provided with shafts 32 which are arranged coaxially to the Aohse of the element and are detected by respective spring carriers 33 (One of these is shown in Fig. 4), which in turn is firmly connected to the inside of the panel H by rivets are. Portions of the panel 14 extend to each point occupied by a flow guide element 25 1, as seen in FIGS. 1, 3 and 4.

Backwards with respect to the space A of the device, a rear space D is provided which passes through the central opening in the vehicle cabin roof with a space E of the air conditioning unit directly above room D. The space E is in connection with the inlet of the fan 12, which delivers air to the evaporator. The space D is in communication with the cabin interior through an opening 35, which as an inlet for stale air for the air conditioning unit 2 serves.
