Problems solved by technology

Therefore, the volume of the through-hole also limits the length of the throttle valve side span (portée latérale) - which causes problems with sealing performance and limits the air flow cross-section
Also, there is mutual interference between the moving parts and the retaining lugs of the actuator attachment collar

Embodiment Construction

[0079] [78] FIG. 1A schematically shows a housing / actuator assembly 1 comprising a fixing device for attaching an actuator 2 to a housing 4 according to the invention. The assembly 1 comprises a casing 4 equipped with walls delimiting an interior space in which a movable mechanism is housed. The mobile part has an axis of rotation intended to be driven by an external actuator 2 .

[0080] [79] Here, and in the following description, the terms "inner", "outer" or "outer" are used with reference to the walls of the enclosure. In particular, the element called "inner" is arranged on the side of the enclosure wall, on which side said movable part 41 is located, while the element called "outer" or "outer" is arranged on the wall the other side of the

[0081] [80] The actuator 2 is formed by a drive motor with a drive shaft 22 extending along the axis D. The drive shaft can be in direct or indirect contact with the axis of rotation of the mobile part 41 .

[0082] [81] The asse...

Abstract

The invention provides a fixing device for fixing an actuator 2 to a box cover 4, especially used for vehicle. The actuator is used for driving a free mechanism 41 disposed within the box cover. The fixing device includes a fixing member for associating the actuator to the box cover. The fixing member includes two connection rings 20, 40 for conjugation which are respectively arranged on a connection face 28 of the actuator and a connection face 48 of the box cover. The said connection rings are fit for being mounted at the exterior of the box cover in a male / female manner.

Description

technical field [0001] [01] The invention relates to a housing and actuator mounting, in particular for a motor vehicle. Background technique [0002] [02] The actuator is used to actuate a movable piece installed in the enclosure, such as a shut-off valve (volet d'obturation) of air conditioning and / or heating equipment (HVAC). [0003] [03] The actuator is usually provided with a drive shaft which is used to drive the moving part in rotation after the actuator is secured to the case. [0004] [04] The fastening device usually includes fastening means for coupling the actuator to a wall of the enclosure. [0005] [05] In known embodiments, the fixing part is of the snap-in type. Said type of fastening means comprises a connecting collar (collarette de raccord) arranged on the actuator and a through-hole arranged in the wall of the casing. The actuator attachment collar is dimensioned such that it is inserted into the through hole of the housing. The actuator connecting ...
