Abstract:
A control valve (10) for a fluid circulation circuit comprises a body (12) which is equipped with a fluid inlet (18) and with at least two fluid outlets (20, 22, 24) and which delimits a housing of revolution for an adjusting element (26) able to rotate about an axis of rotation (XX) and to adopt various angular positions to control the distribution of fluid through the outlets. The adjusting member (26) is surrounded by a sealing ring (42) in the form of an open annulus, which rotates as one with the adjusting member and is arranged with a small clearance around the adjusting member, this allowing the sealing ring to be pressed firmly internally against a side wall (16) into which the fluid outlets (20, 22, 24) open with a view to ensuring sealing under the action of the pressure of the fluid. Application in particular to motor vehicle fluid circuits.
Abstract:
A windshield wiper device generally comprises a shaft supported by a fixed element, such as the base of a housing of a geared motor, this shaft being rotatable around an axis by a reduction gear system and connecting rod assembly; an angle damping device is disposed between the fixed element and the shaft. According to the invention, the angle damping device comprises at least one elastic washer axially compressed along the axis of the shaft. The axial compression of the elastic washer is controlled by a cam having a variety of angular sectors for moving axially along the shaft.
Abstract:
A heat exchange block (1) for a motor vehicle, includes at least one heat exchanger (2, 3, 4), wherein the block (1) is intended to be disposed behind a front grille (6) of a vehicle and to be traversed by air originating from an opening in the grille. The block includes a group of louvers (13) that can move between an open position and a closed position in order to modulate the flow of air (A) passing through the heat exchanger (2, 3, 4) and a channel (9) that can be disposed between the opening in the grille and the heat exchange block (1). The heat exchange block is suitable for any motor vehicle, but, in particular, hybrid and electric vehicles.
Abstract:
The present invention concerns a hole sealing device (1) in particular for a main air inlet in the front face of a motor vehicle, comprising:—a support frame (5) comprising at least one shutter (3) pivoting about a pivot pin (A) between an open position and a closed position,—at least one pivot rod (7), said at least one shutter (3) having a link pin (B) linking it with said pivot rod (7),—at least one actuator (9) for moving the pivot rod (7) and controlling the position of the at least one shutter (3), said at least one shutter (3) being linked to a resilient opening means (15) at least comprising a mobile part (151), a resilient member (152) and a retaining member (153) for said resilient member (152).
Abstract:
A control valve for a fluid flow circuit comprises a body that has a fluid inlet and at least two fluid outlets (20, 22, 24) and that defines an axisymmetric housing for a modulating member capable of rotating about an axis of rotation (XX) and adopting different angular positions to control the distribution of the fluid through the outlets. The body comprises a side wall (16) into which the fluid outlets open. The side wall (16) and/or the modulating member comprises sunken areas (EV) and non-sunken areas (CR), the sunken areas (EV) serving to reduce the surface area of the modulating member (26) in contact with the side wall (16).
Abstract:
The invention relates to a module for a cooling circuit of a motor vehicle engine comprising at least one control valve (18) allowing a circulation according to at least one normal mode. The module also comprises a thermal safety device (30) for the circuit. The thermal safety device (30) is 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.
Abstract:
A direct current electric motor, especially one for driving a fan or blower in a motor vehicle ventilating system, has a motor shaft, a bearing ring around the free end of the motor shaft, and a casing which includes an end plate carrying a bearing element formed with a cylindrical internal face, which defines a housing in which the bearing ring is received. The fixed bearing element has a base portion and a free edge at the opposite axial end of the bearing element from the base. The bearing is formed with reliefs adjacent to the free edge of its fixed element. These reliefs project radially towards the axis from the internal face of the bearing.
