Abstract
The air blower unit includes a casing having a lower wall, and upper wall and two opposed side walls, which together define two open and opposed end faces of the same profile. The casing also includes a mounting frame, together with an air blower which is mounted within the casing and which comprises a blower rotor, a drive motor for the blower rotor, and two symmetrical half shells which are mated together to define a volute chamber in which the blower rotor and the motor are mounted. This unit is readily adaptable to two different configurations, according to whether the vehicle in which it is to be installed is of the left hand drive or right hand drive type.
Claims11
An air blower unit for a heating and ventilating system of a motor vehicle, comprising a casing and an air blower mounted in the casing, the air blower comprising two generally symmetrical half shells mated together to define a volute chamber, a motor within the volute chamber, and a blower rotor coupled with the motor so as to be driven thereby, each half shell having a central opening and a lateral half opening, such that one of the central openings serves as an air inlet and the other to support the motor, while the two said lateral half openings together define an air outlet, said casing comprising an upper wall, a lower wall, and two opposed side walls together defining two open and opposed end faces having the same profile, the casing further including a mounting frame defining a datum plane and two opposed mounting sides which are symmetrical about said datum plane, so that the mounting frame can be fitted over the air outlet of the air blower on either one of its two said mounting sides indiscriminately, whereby to obtain two casing configurations in which the mounting frame retains the same spatial orientation with respect to the casing.
