Abstract: The invention relates to an electric fan set, notably for a motor vehicle heating, ventilation and/or air conditioning installation, comprising: a motor, a motor support (11), and a control module support (23) forming a bearing support for the motor. According to the invention, the motor support (11) and the control module support (23) each comprise at least one fixing zone, the fixing zones being able to cooperate with one another for the assembly of the motor support (11) with the control module support (23), according to at least two different positions of the motor support (11) relative to the control module support (23).

Abstract: A motor support unit designed to be mounted on a shell of a heating, ventilation and/or air-conditioning installation is disclosed. Additionally, the motor support unit includes a motor and a motor support. The motor support unit further includes a connection piece for fitting on the motor support and may also be intended for fitting on the shell in such a manner as to form an interface between the motor support and the shell. Furthermore, the connection piece and the motor support are formed by two distinct pieces.

Abstract: A part for uncoupling a motor and a motor mounting part thereof, that includes a rigid connecting part that is to be coaxially placed in a central portion of a stator core and includes a central ring for receiving a rotatable shaft of a rotor of the motor, from which at least two arms extend, free ends of which are intended to abut against an inner wall of the stator core and form at least two spaces for placing a flexible uncoupling pad that radially extends from an outer surface of the central ring of the rigid connecting part, against which the uncoupling pad abuts, to a rigid assembly tab that is to axially extend into the central portion of the stator core, near the inner wall of the stator core, while being rigidly connected to the motor mounting part.

Abstract: The invention relates to a motor support unit (1), for a heating, ventilation and/or air-conditioning installation, particularly for a motor vehicle, designed to be mounted on a shell (2), of the heating, ventilation and/or air-conditioning installation, the motor support unit (1) comprising: a motor (3), and a motor support (11). According to the invention, the motor support unit (1) comprises furthermore a connection piece (15?), on the one hand, fitted on the motor support (11) and, on the other hand, intended for fitting on the shell (2) in such a manner as to form an interface between the motor support (11) and the shell (2), the connection piece (15?) and the motor support (11) being formed by two distinct pieces.

Abstract: An air pulsation device according to the invention comprises an electric motor (2) comprising a rotor and a stator (14). The stator comprises teeth arranged so that an interspace (30) for winding a coil is formed between two adjacent teeth. The stator is in contact with a means for supporting the electric motor, which is metallic and electrically connected to an electrical earth. At least one screen (50) is electrically connected to the support means, the said at least one screen comprising closing means (62, 68) which extend axially so as to fill at least one of the said interspaces between two teeth of the stator (14).

Abstract: The invention mainly relates to a part for uncoupling a motor and the mounting thereof, which is characterized in that it comprises a rigid connecting part (8) that is to be coaxially placed in the central portion (3) of the core of the stator (2) and includes a central ring (11) for receiving the rotatable shaft of the rotor of the motor (1), from which at least two arms (12) extend, the free ends of which are intended to abut against the inner wall (13) of the core of the stator (2) and form at least two spaces for placing a flexible uncoupling pad (9) that radially extends from the outer surface of the central ring (11) of the rigid connecting part (8), against which the uncoupling pad (9) abuts, to a rigid assembly tab (10) that is to axially extend into the central portion (3) of the core of the stator (2), near the inner surface (13) of said core of the stator (2), while being rigidly connected to the motor mounting (4).

Abstract: A module for a cooling circuit of a motor vehicle engine includes at least one control valve allowing a circulation according to at least one normal mode. The module also includes a thermal safety device capable of allowing a circulation according to another mode called the short-circuit mode in the event of failure of the normal circulation mode.

Abstract: A control valve (10) for a fluid circulation circuit comprises a valve body (12) having a bottom wall into which an axial orifice emerges and a side wall (16) into which side orifices (20, 22, 24) emerge, the valve body delimiting a housing of revolution for a regulating member (26) capable of rotating about a rotation axis XX and of taking various angular positions to control the distribution of the fluid through the orifices. The regulating member (26) is surrounded by a sealing segment (42) in the shape of an open ring and elastic means are provided to separate two ends (44, 46) of the sealing segment in order to deform it radially outward and thus ensure that the sealing segment is pressed against the valve body housing. Application particularly to the fluid circuit of motor vehicles.
