Abstract: An air vent is provided for directly introducing air into a passenger compartment of a vehicle. The air vent has at least one outlet opening and at least one deflecting surface which is arranged in the region of the outlet opening, which runs radially outwards with respect to a flow direction of the air flowing in the direction of the deflecting surface, and by which the air flowing in the direction of the deflecting surface can be deflected radially outwards using the Coanda affect. An intuitively controllable and inexpensively producible air vent is achieved in that the shape and arrangement of the deflecting surface is adapted to a flow speed of the air flowing in the direction of the deflecting surface such that it is equally probable that the air flowing in the direction of the deflecting surface is deflected radially outwards by the deflecting surface or it is not.

Abstract: Display cases may include deflectors and fans. The deflectors may alter air currents generated by fans to provide an air current to display portions of the display case. In some implementations, the altered air current may have a first portion with a velocity that is greater than a velocity of a second portion, where the first portion is closer to a display portion of the display case.

Abstract: An air-conditioner for a vehicle, may include a casing having an upper outlet and a lower outlet, with an air flow space defined in the casing and including an upper space and a lower space to guide air to the upper outlet and/or the lower outlet, an evaporator installed in the casing and selectively communicating with the upper outlet through the upper space, and a distributing partition wall to partition the lower space into a receiving space to receive a heating member therein and selectively communicate with the upper space and at least a partitioned space to communicate the heating member with the lower outlet, thus guiding the air to a side portion of the casing.

Abstract: A vehicular air conditioning apparatus includes a casing constituted by respective air passages. The casing has a vent opening and a defroster opening at an upper portion thereof. The vent opening is disposed on a forward side of a vehicle with respect to the defroster opening. A pair of defroster ducts extend in lateral directions respectively from side portions of the defroster opening, and center vent ducts are disposed in a straight line fashion from the vent opening and oriented rearwardly of the vehicle between the pair of the defroster ducts. The center vent ducts open only in the vehicle compartment. In a bi-level mode, a third front passage on the downstream side of the evaporator extends upwardly in a straight line fashion.

Abstract: An air conditioning system for a passenger compartment of a road vehicle; the air conditioning system has an elongated upper air inlet, which comes out through a top surface of a dashboard of the passenger compartment, close to a windscreen, extends substantially along the whole of the top surface of the dashboard, and is directed towards the passenger compartment to direct airflow tangent to the top surface of the dashboard and over the top surface.

Abstract: An air vent for a ventilation system in a vehicle is disclosed that has an air circulation chamber (1) defined by a housing (9) that has a generally bulged shape. An inflow duct (2) is connected to this housing and opens into the circulation chamber (1), the housing having a perforated wall area (3). An air stream, in use, enters the circulation chamber (1) through inflow duct (2), circulates through the air circulation chamber and exits through the perforated wall area. The air vent further comprises a movable air deflection member disposed to deflect the air stream transversely to an axial direction of the inflow duct.

Abstract: A clearing system for external mirrors and side windows of a vehicle provides a flow of compressed warm air to an air distribution unit equipped with a number of openings to direct the flow of air towards the surface of the mirror or a side window. In one embodiment, the air compressor, the air heater and an optional air filter are located in the housing of the external mirror. In another embodiment, a supplemental air distribution unit is provided to be mounted along the door of the vehicle to increase the coverage area of the side window. In a further embodiment of the invention, the system is made adjustable for allowing the most appropriate angle for the air openings towards the mirror and the side window. Provisions are also made to use the system for newly designed vehicles and incorporate the elements of the system into the design of the vehicle door. Alternately, an add-on elements are described to allow existing vehicles to benefit from the system.

Abstract: A female screw portion is formed around an axis of a rotor of a step motor to penetrate through the rotor in an axial direction of the rotor. A male screw portion is formed on an outer peripheral surface of a screw shaft so that the screw shaft is screwed into the female screw portion. The screw shaft is inserted in a ring rod, and a connection clip portion is connected to the ring rod. When the rotor rotates, the ring rod reciprocates linearly in the axial direction of the rotor, and vertical fins rock in the axial direction of the rotor.

Abstract: A air outlet for a passenger compartment of a vehicle has a duct forming a jet of air, a pair of lateral sidewalls, bounded by the top and bottom walls diverging from each other from their upstream ends to their downstream ends at a rate sufficient to preclude a stable wall effect and for causing aperiodic oscillation of the jet into the passenger compartment of said vehicle. Various means are disclosed to further destabilize the wall effect.

Abstract: A method and apparatus of maximizing transfer of thermal energy to or from an oscillating or swept air jet propogated over a windshield. The air jet is projected through short distances in ambient from a nozzle properly aimed at said windshield. The wavelength of the oscillating or swept jet is caused to be greater than the nozzle distance from windshield and smaller than the length extent of windshield in the direction of air jet propogation across it whereby there is less of loss or gain of thermal energy from said air jet in the space between said nozzle and said windshield and a maximum transfer of thermal energy between the windshield and air jet by lessening the thickness of any insulating boundary layer.
