A fluid discharge device includes a base portion defining a fluid flow passage and having an opening at a downstream end of the fluid flow passage, and a grill portion disposed to adjust a flow direction of the fluid blown from the opening. The grill portion includes a flow passage forming body defining a main flow passage and an auxiliary flow passage. In the flow passage forming body, the auxiliary flow passage surrounds the main flow passage and the auxiliary flow discharged from the auxiliary flow passage flows outside of the main flow discharged from the main flow passage. The flow passage forming body is configured such that a direction of the auxiliary flow discharged from the auxiliary flow passage corresponds to the direction of the main flow discharged from the main flow passage, when the flow direction of the fluid blown out of the opening is adjusted.

A register includes an annular fin that can improve the directivity of air conditioning air while suppressing increase in the number of parts. A front fin includes an annular-shaped annular fin portion. A bezel has upstream side inclined surfaces formed on inner peripheral surfaces facing with each other in the shorter side direction (vertical direction) of an air blow outlet. The upstream side inclined surfaces incline toward a direction of approaching the annular fin portion from an upstream side toward a downstream side of an air blowing direction. An air conditioning air flowing in the air blowing direction is guided to the annular fin portion side by the upstream side inclined surfaces.

An air vent for a vehicle includes a housing (10) and an air-guiding element (30), wherein the air-guiding element (30) is mounted in the housing (10) so as to be pivotable in different directions about at least one centre of rotation (D), wherein a first drive element acts on the air-guiding element (30) at a first engagement point (A.sub.1), and a second drive element acts on the air-guiding element (30) at a second engagement point (A.sub.2), wherein the second engagement point (A.sub.2) defines, with the at least one centre of rotation (D) of the air-guiding element (30), a first pivot axis (S1) about which the first drive element pivots the air-guiding element (30), and wherein the first engagement point (A.sub.1) defines, with the at least one centre of rotation (D) of the air-guiding element (30), a second pivot axis (S.sub.2) about which the second drive element pivots the air-guiding element (30).

Aspects presented herein provide a solution to the problem of conditioned air blown into the passenger compartment in a concentrated direction and the discomfort that users may experience from the concentrated conditioned air. The apparatus includes a plate portion having a central flat surface and angled side surfaces, and a ball joint extending from a rear surface of the plate portion. The apparatus includes a stem portion having a socket and a plurality of legs. The stem portion may be removably coupled to the plate portion at a rear surface of the central flat surface. The ball joint of the plate portion may be received within the socket such that the positioning of the plate portion may be adjustable.

Provided is a wind direction adjustment apparatus capable of adjusting a wind direction with a simple configuration while improving an appearance. A wind direction adjustment apparatus 1 includes a cylindrical case body 3 whose one end side is contracted in a predetermined direction, and through which air passes from the other end side to the one end side. The wind direction adjustment apparatus 1 includes a cylindrical wind direction adjustment body 26 disposed to be movable in at least the predetermined direction inside the one end side of the case body 3.

Two disks are consecutively disposed transversely to a flow direction in an air vent for a passenger compartment of a motor vehicle, serving as air deflection elements that include mutually intersecting slots, through which a rod that is pivotably mounted in a ball and socket joint passes, so that the air deflection elements can be moved transversely in the air vent by way of the rod. By moving the air deflection elements, an air current through the air vent can be guided to the side, and thus air flowing out of the air vent can be guided obliquely to the side in any arbitrary direction.

A vent unit includes a bezel installed on a vehicle and formed in a ring shape with a flow hole at the center, and a spacer overlapping and coupled to the bezel and formed in a ring shape rotating relative to the bezel. The bezel has a plurality of first through-holes circumferentially spaced apart from one another, and the spacer has a plurality of second through-holes circumferentially spaced apart from one another such that conditioning air is discharged to an interior through the second through-holes and the first through-holes when the second through-holes are aligned with the first through-holes by circumferential rotation. The vent unit further includes a wing disposed in the flow hole of the bezel and coupled to the spacer through a hinge shaft. The wing controls discharge of conditioning air through the flow hole by axially rotating, and circumferentially relatively rotating together with the spacer.

An outlet assembly having a plurality of different operating modes for improving air flow in an air distribution system is provided. The assembly includes a first blocking element supported by a first wall of a housing for movement between blocking and unblocking positions within a cavity of the housing. The first blocking element prevents a first layer of air from flowing immediately adjacent the first wall in its blocking position. A second blocking element is supported by a second wall of the housing for movement between blocking and unblocking positions within the cavity. The second blocking element prevents a second layer of air from flowing immediately adjacent the second wall in its blocking position. An actuator subassembly including a selector member is supported for movement between a plurality of predefined positions which correspond to first and second blocking modes and a nominal unblocking mode.

A vehicle air conditioner includes: a heating passage for sucking in air inside the vehicle cabin with a heating fan and supplying the air to a condenser, and supplying the air having passed through the condenser into the vehicle cabin from a heating air outlet; a cooling passage for sucking in the air inside the vehicle cabin with a cooling fan and supplying the air to an evaporator, and supplying the air having passed through the evaporator into the vehicle cabin from a cooling air outlet; a cooling inlet opening and a cooling outlet opening capable of communicating both sides of the condenser of the heating passage with outside of the vehicle cabin; and a heating inlet opening and a heating outlet opening capable of communicating both sides of the evaporator of the cooling passage with the outside of the vehicle cabin.

An illuminated aircraft passenger cabin gasper comprises an air outlet for outputting a flow of air into an aircraft passenger cabin and an air guide, movably arranged within the air outlet for adjusting the flow of air that includes a light guide. The gasper also includes at least one light source, arranged adjacent to the light guide for coupling light into the light guide. The light guide has a light output surface for coupling light out of the light guide into the aircraft passenger cabin.
