An air-handling system includes a housing having a passageway formed therethrough. A diverter is rotatably coupled to the housing, and includes a door disposed in the passageway for selectively opening and closing the passageway. A shaft of the door extends through a first opening of the housing, and extends outwardly therefrom, defining a first axis. A lever is coupled to the shaft of the diverter. A flexible tab is disposed axially outwardly of the lever and is positionable in a first position and a second position. In the first position, a distal end of the tab is positioned radially inwardly of an outer circumferential surface of the lever, and in the second position the distal end of the tab is positioned radially outwardly of the outer circumferential surface of the lever. The distal end is moveable about a second axis, parallel to the first axis.

A vehicle air-conditioning unit has an air conditioning case and a case interior member. The air conditioning case defines a case passage in which air flows toward a vehicle compartment. The air conditioning case has a recess defining portion that is located in the case passage and defines a recessed portion. The case interior member has a guide portion and a cover. The guide portion guides the air flowing in the case passage. The cover is located in the recessed portion. The cover prevents the air, flowing in the case passage, from flowing into the recessed portion.

The present invention relates to a damper door (1) having an axis of rotation (3), a first face (5), and a second face opposite the first face (5), said first (5) and second faces of the damper door (1) defining a plane, said damper door (1) comprising: a rotation shaft (9) projecting from each side of the plane defined by the first (5) and second faces of the damper door (1), and at least one side wall (11) having a flat surface arranged radially with respect to the rotation shaft (9), characterised in that the rotation shaft (9) has, in the plane of the at least one side wall (11), a semi-elliptical shape (13) extending over the side wall (11) and comprising a large diameter (G1) coinciding with the axis of rotation (3) of the damper door (1) and a small radius (P1) parallel to the plane of the at least one side wall (11).

An HVAC case having an airflow junction. A mount is at the airflow junction and is configured to individually mount a door and an airflow blocker at the airflow junction. The door is mounted at the mount of the airflow junction to configure the HVAC case for use with HVAC systems configured for airflow through the airflow junction. The airflow blocker is mounted at the mount of the airflow junction to configure the HVAC case for use with HVAC systems not configured for airflow through the airflow junction.

Provided is a vehicle air-conditioning device in which a lever (7) for turning a damper is rotatably fitted and supported on a unit casing (2), wherein one of a support part (13) on the unit casing (2) side and a fitting part (8) on the lever side is provided with an elastically deformable fitting claw (27), while the other of the support part (13) and the fitting part (8) is provided with a fitting hole (24), into which the fitting claw (27) is fitted and engaged, and a bearing boss part (23) and a fitting shaft part (25), which are rotatably fitted together with a bearing clearance between them, are provided on the outer periphery of the fitting claw (27) and the fitting hole (24).

Provided is an intake system of an air conditioning system for a vehicle, which is configured for simultaneously satisfying two conflict conditions of improving heating performance by increasing the inflow of inside air and of reducing the generation of moisture on a window glass, wherein a scroll case, in which a blower is mounted, is provided with a second partition member for dividing a passage, which is formed at an outlet port and includes a blower chamber around a blower fan, into an upper passage and a lower passage, and a flow guide for guiding air, which is separated by a first partition member and is introduced into the scroll case from an inlet case, to the respective upper and lower passages.

A climate control system for a vehicle comprises a housing and a diverter. The housing has a first conduit formed therein. The first conduit includes a first subconduit formed in an intermediate portion of the first conduit and a second subconduit disposed adjacent an end of the first subconduit. The diverter is rotatably disposed within the first conduit, and includes a first member having an outer edge and an offset edge. The outer edge is disposed on a first planar portion of the first member and configured to sealingly contact a wall of the first subconduit when the diverter is in a first position. The offset edge is disposed on a second planar portion of the first member and configured to sealingly contact a portion of the second subconduit when the diverter is in the first position.

A bearing arrangement has a bearing pin and a coupling pin, and a second bearing component, which components are mounted on a wall so as to be rotatable about a common axis of rotation. The bearing pin extends along, and the coupling pin extends eccentrically to the axis of rotation. The bearing pin is accommodated in a bearing opening of the wall. The coupling pin is accommodated in a guide slot of the wall and projects from the guide slot. The second bearing component has a first opening, in which the bearing pin is accommodated, and a second opening arranged eccentrically to the first opening, in which second opening the coupling pin is accommodated. The bearing pin is connected to the second bearing component via a lock, and the second bearing component is supported on the coupling pin.

An air conditioning system includes an air conditioning unit that includes an introduction part that introduces air, a plurality of temperature adjustment parts that cool or heat introduced air, and a discharge part that discharges cooled or heated air to an inside of the vehicle. The air conditioning system further includes an outdoor duct connected to a discharge-part side of the air conditioning unit and extending toward an outdoor side of the vehicle to discharge the cooled or heated air to an outside of the vehicle. Additionally, the air conditioning system includes an outdoor door provided on the outdoor duct or on the discharge part of the air conditioning unit around the outdoor duct to control air flow through the outdoor duct.

A car air conditioning system has a pneumatic circuit to feed an air flow into a passenger compartment of a vehicle, and a cooling circuit to cool the air flow fed along the pneumatic circuit; the pneumatic circuit being provided with a three-way joint, which has an inlet connected to a first pneumatic duct, a first outlet connected to a second pneumatic duct, a second outlet communicating with the passenger compartment of the vehicle, and a shutter, which is movable from and to a closing position, wherein the inlet is separate from the two outlets.
