The invention concerns a ventilator for a motor vehicle passenger compartment, intended to deliver an air flow towards a space to be conditioned, which comprises: an opening through which an air flow flows during operation, a flared guiding surface (S), extending from the opening, a needle valve (25) comprising a needle valve head (27) with: a tip (29) situated at the end of the needle valve (25), a maximum width portion corresponding in shape to the opening (O), with dimensions of between 80% and 100% of those of the opening (O), a base (33) flared in the direction of flow linking the head (29) to an elongate body (31), the needle valve (25) being able to move in translation between two end positions including: a deployed end position in which the widest portion of the needle valve head (27) is downstream from the opening (O) in the direction of the space to be conditioned, the air flow then being laminar and guided by the guiding surface (S) in a divergent flow, a retracted end position in which the widest portion of the needle valve head (27) is upstream from the opening (O), the air flow then being laminar and guided by the tip (29) of the needle valve (25) in a convergent flow.

A wind direction adjuster enabling an operation of a louver with a stable operation load and providing an excellent operation feeling is provided. An axial support body is axially supported to a cylindrical case body turnably so as to have an axis along a direction crossing an axial direction of the case body. A louver is axially supported to the axial support body turnably so as to have an axis along a direction crossing the axis of the axial support body. A ball unit is set in any one of the case body and the louver as a load setting unit that sets a turning load of the louver. A receiving unit that slidably receives the ball unit is set in the other one of the case body and the louver. A coil spring urges one of the ball unit and the receiving unit to be pressed against the other.

The present disclosure relates to an air vent structure. The air vent structure at least includes a tubular housing through which an air-conditioned air flows, and an annular finisher in an air flow-out end of the housing. The air vent structure further includes an air restrictor that restricts the inflow of the air-conditioned air into a clearance between the air flow-out end of the housing and the finisher.

A personal valve apparatus may include a nozzle, a valve seat, and a moveable poppet valve. The nozzle may comprise an inner air-flow surface having a nozzle cavity extending through the inner air-flow surface. The valve seat may comprise a seat member disposed at an end of the inner-air-flow surface with the seat member disposed over the nozzle cavity. The moveable poppet valve may be disposed over the seat member and the nozzle cavity. The moveable poppet valve may comprise a convex surface. When the moveable poppet valve is in an open position, the convex surface may be disposed over and apart from the seat member to allow air to flow from the nozzle cavity, against the convex surface, between the seat member and the convex surface, and beyond the seat member. The convex surface of the poppet valve may reduce air turbulence, drag, flow separation, and/or noise within the valve apparatus.

On a centerline parallel to an air blowing direction inside a retainer, a ball joint with a ball is disposed. On a turning louver, a central axial support portion from which axial support portions are projected radially is disposed at the center of a cylindrical frame. The central axial support portion is attached tiltably and turnably by fitting a ball hole provided at the center with the ball. Inside the cylindrical frame, movable fins are axially supported turnably at substantially even intervals by pivots in radial directions, and the inner-side portions of each movable fin are axially supported by each axial support portion. To the front surface side center of the central axial support portion, an operation portion is fitted turnably around the centerline of the turning louver, and the operation portion is linked to the inner-side portions of each movable fin via a bevel gear mechanism.

A damper opening and closing device includes an outer cylinder, an inner cylinder that is disposed inside the outer cylinder, is supported movably relative to the outer cylinder and has a fluid passage therein, and a damper group that includes a plurality of dampers disposed in the fluid passage so that the fluid passage is openable and closable. The plurality of dampers are arranged in a circumferential direction of the fluid passage and disposed in the fluid passage in such a way that inner peripheral edges of the dampers are opposed to each other. The damper opening and closing device further includes an angle control unit configured to control the tilt angle of the damper in conjunction with movement of the inner cylinder relative to the outer cylinder.

The invention relates to a cardan mounting for an air vent, comprising a fixed part and a moving part, which are each pivotably attached to a cardan ring, wherein the two pivoting axes are arranged at right angles to one another. The cardan ring is elastically deformable, circular-ring-shaped in the uninstalled state and extended along one pivoting axis and compressed along the other pivoting axis, as compared with the circular shape, in the installed state. The invention furthermore relates to an air vent having a cardan mounting of this kind.

A personal valve apparatus includes an air inlet, an air outlet, a nozzle, a valve seat, and a moveable poppet valve. The nozzle comprises an inner air-flow surface having a nozzle cavity, extending along the inner air-flow surface, in communication with the air inlet. The valve seat comprises a seat member disposed over the nozzle cavity at the air inlet. The moveable poppet valve is disposed over the seat member and the nozzle cavity at the air inlet. The moveable poppet valve comprises a convex surface. When the moveable poppet valve is in an open position, the convex surface is disposed over and apart from the seat member at the air inlet and configured to allow air to flow from the air inlet, against the convex surface at the air inlet, between the seat member and the convex surface at the air inlet, into and through the nozzle cavity, and out of the air outlet.

A temperature control gasper apparatus for vehicle interiors such as aircraft cabins. Airflow temperature, volume and orientation are integrated and controlled by the gasper apparatusat the point of use of the gasper apparatus. The temperature control gasper apparatus includes a mixing chamber, a temperature control dial, and an airflow control nozzle assembly. The temperature control gasper apparatus provides airflow output control with rotation of a grip member of the nozzle assembly relative to a ball portion of the mixing chamber, temperature control by rotation of a handle portion of the temperature control dial relative to the ball portion of the mixing chamber, and airflow direction control by movement of the ball portion of the mixing chamber relative to a socket portion of the mixing chamber fixed to the vehicle interior.

The present invention relates to an air vent for a vehicle, the air vent enabling adjusting of an air discharge direction of an air vent, which is for supplying the outside air to the inside of a vehicle, to various angles as well as diffusing the air being discharged.
