According to the invention, the air guiding members comprise at least three flaps (27, 28, 30), one of these being a central flap (27) and two lateral flaps (28, 30) arranged one on each side of the central flap (27), said flaps (27, 28, 30) being positioned between the said two distinct air inlets (24, 26) of the air intake housing (21) so as to be able to move about a single axis of pivoting (33). The invention also relates to a suction blower (1) comprising such an air intake housing (21) and to a corresponding heating, ventilation and/or air conditioning device.

Abstract: A heating, ventilation and/or air-conditioning device for a motor vehicle, with a housing which includes a first duct for a first air stream, a second duct for a second air stream, a partition placed inside the housing so as to separate the ducts, a first heat exchanger arranged in the ducts, said heat exchanger being common to the two ducts, a second heat exchanger which is located downstream of the first heat exchanger and is arranged within a single duct, a first flap located downstream of the second heat exchanger, an air stream guide wall which is arranged inside the first duct, downstream of the first heat exchanger, and directs the first air stream in the direction of the first flap. The housing includes a space between the air stream guide wall and the first flap so that the first flap will not abut against the air stream guide wall.

Abstract: The invention concerns a control device (1) for a heating and/or ventilation and/or air conditioning installation of a motor vehicle, the installation comprising an air treatment unit (9) comprising air outlets intended to open into a zone (ZG, ZD) of the passenger compartment of the vehicle, including at least first and second air outlets, and at least first (21) and second (23, 25) members for mixing the air flow. According to the invention, the device (1) comprises a user interface (5) comprising at least first (51) and second (53) control members, and a control circuit (7) for receiving, from each control member (51, 53), an input signal with its own temperature setpoint, and for delivering separate control signals for controlling the first and second mixing members (21, 23, 25).

Abstract: A heating, ventilating and/or air-conditioning device for a motor vehicle, comprising a housing that defines a flow channel having at least a first duct for the flow of a first stream of air, defining a first air outlet, at least a second duct for the flow of a second stream of air, defining a second air outlet, at least one mixing chamber communicating with the respective air outlets of said ducts, and at least one mixing flap comprising a first sliding door arranged so as to control the apportionment of the first stream of air and second stream of air in said at least one mixing chamber, said at least one mixing flap being arranged so as to be movable between a first end position, in which it closes the first duct, and a second end position, in which it closes the second duct.

Abstract: The invention relates to a heating, ventilation and/or air-conditioning device (1) for a motor vehicle, comprising a housing (2) defining a flow channel (3) for an air flow, in which are arranged a first heat exchanger (4), a second heat exchanger (6), the first (4) and second (6) heat exchangers being arranged in substantially orthogonal planes, a bypass path (28) of the second heat exchanger (6) and at least one air outlet duct (12,14,16), each air outlet duct (12,14,16) being configured to guide the air flow in particular towards different regions of a vehicle passenger compartment. According to the invention, a mixing flap (30) comprising a sliding door is arranged in the flow channel (3) so as to be able to close the bypass path (28) and/or the second heat exchanger (6), and a second dispenser flap (22) comprising a sliding door is arranged so as to be able to at least partially close a first of said air outlet ducts (12,14,16). The invention also relates to a motor vehicle comprising such a device.

Abstract: The invention relates to an air intake housing (21), in particular for a heating, ventilation and/or air conditioning device, comprising: —at least two distinct air inlets (24, 26), and —air guiding members (27, 28, 30) configured to direct at least one air flow that is intended to be admitted into the air intake housing (21). According to the invention, the air guiding members comprise at least three flaps (27, 28, 30), one of these being a central flap (27) and two lateral flaps (28, 30) arranged one on each side of the central flap (27), said flaps (27, 28, 30) being positioned between the said two distinct air inlets (24, 26) of the air intake housing (21) so as to be able to move about a single axis of pivoting (33). The invention also relates to a suction blower (1) comprising such an air intake housing (21) and to a corresponding heating, ventilation and/or air conditioning device.

Abstract: A method of calibrating a test platform for microwave packages is provided. According to the invention, the conventional Thru, Reflect and Line standard patterns are replaced by microwave standard packages fulfilling similar functions, the test platform being adapted accordingly. The use of standard packages makes it possible to retain the same electrical interface between each of the packages and the test platform. The invention also relates to a method of determining an electrical length LC of an etched line linking two microwave feeds of a microwave standard package. The standard package may be connected to the test platform. According to the invention, various electrical lengths of the test platform are measured so as to be able to deduce therefrom the electrical length LC of the etched line of the standard package. The invention exhibits the advantage of obtaining the electrical length LC by measurement rather than by modeling.

Abstract: An air distribution device comprises a casing (10) provided with a cylindrical wall (12) having at least one air passage opening (14, 16), a shutter (20) mounted so as to pivot with respect to an axis of rotation (X—X) and having a generally cylindrical obturation wall, which is mounted so as to movable with respect to a body of the shutter, consisting of two plates, in a direction substantially radial with respect to the axis of rotation (X—X) of the shutter by virtue of movement means (46, 48) synchronised with the rotation of the shutter, which makes it possible to move the obturation wall (24) away from the wall (12) when the shutter is in an open position (P1, P2) and bring the obturation wall (24) closer to the wall (12) of the casing when the shutter is in a closed position.
