An actuator may during operation adjust the valve in the transverse direction between a first position, in which the valve fluidically separates the second supply duct from the mixing duct and opens a fluidic connection between the first supply duct and the mixing duct, and a second position, in which the valve fluidically separates the first supply duct from the mixing duct and opens a fluidic connection between the second supply duct and the mixing duct, wherein the first guide section has a first thickness running in the height direction and which is smaller than a second thickness of the second guide section running in the height direction in such a manner that both guide sections are each in contact with both guide walls of the associated guide.

A modular door for a vehicle HVAC system includes a first subcomponent, a second subcomponent, and a customized subcomponent. The first subcomponent forms a first portion of the modular door and is configured to be standardized for first and second vehicle HVAC systems. The second subcomponent forms a second portion of the modular door and is configured to be standardized for the first and second vehicle HVAC systems. The customized subcomponent is configured to separate the first subcomponent from the second subcomponent. The customized subcomponent is also configured to connect the first subcomponent to the second subcomponent such that the modular door is configured for the first vehicle HVAC system.

A heating, ventilation, and air-conditioning (HVAC) assembly for supplying different mixed air flows simultaneously is disclosed. The assembly includes first blend kinematics configured for allowing passage of a first air flow, second blend kinematics configured for allowing passage of a second air flow, obtaining means configured to obtain a temperature command indicating a target temperature for two different locations outside the HVAC assembly, identifying means configured to identify a pattern for the first blend kinematics and the second blend kinematics for modifying the first air flow and the second air flow based on the temperature command, and coordinating means configured to coordinate each of the first blend kinematics and the second blend kinematics simultaneously.

The present disclosure includes a heating, ventilation, and air conditioning (HVAC) door diagnostic system. The system has a rotatable hard stop lever that contacts, and restricts movement of, both a first airflow control door and a second airflow control door beyond a stop position when both the first airflow control door and the second airflow control door are present and moving in sync. When one of the first and second airflow control doors is not present or the first and second airflow control doors are not in sync, only one of the first and second airflow control doors will: contact the hard stop lever at the stop position, rotate the hard stop lever, and move beyond the stop position. The HVAC door diagnostic system generates a failure notice when the first airflow control door or the second airflow control door moves beyond the stop position.

A heating, ventilation, and air conditioning (HVAC) airflow distribution module with an outlet closing mechanism for a vehicle including a driver face airflow outlet defined by an HVAC module. A passenger face airflow outlet defined by the HVAC module having a center portion and a side portion. An adaptor including a door driving mechanism to control a telescoping door sub-assembly, which is mounted at the passenger face airflow outlet and is movable between a retracted position at which the telescoping door sub-assembly does not obstruct the airflow through the passenger face airflow outlet by being packaged away from outlets, and any one of a plurality of extended positions at which the telescoping door sub-assembly obstructs the side portion or both the side and center portions of the passenger face airflow outlet at different blocking levels when no passenger is present to save energy, improve fuel economy, and/or increase battery life.

An air vent assembly, in particular for a motor vehicle, with an air vent, which has a housing having an air duct and at least one air deflector blade assigned to the air duct with a trailing edge and a leading edge. Leading edge of the air deflector blade is mounted to be pivotable about an axis of rotation assigned to the trailing edge, and has a decorative device which has at least one fixed decorative blade with a visible edge extending in extension of the trailing edge of the air deflector blade. The air deflector blade is mounted to be pivotable about the axis of rotation by means of a pivot pin on the decorative blade. The decorative blade has a radially open bearing receptacle for the pivot pin, and the housing has a bearing projection.

A door drive mechanism used for a vehicle air conditioning device includes a link mechanism connected to first and second shafts. The link mechanism includes a base member secured to an air conditioner case. The base member includes first and second shaft holes in which first and second shafts are inserted, guide grooves formed around the first and second shaft holes and configured to allow positioning portions to be inserted into the respective guide grooves, and guide portions including inclined surfaces configured to guide the positioning portions to the guide grooves. Moreover, the first and second shafts include the positioning portions protruding radially outward at positions closer to distal ends thereof than first gear portions.

A driving force transmission mechanism configuring a vehicular air conditioning device includes: a driving lever coupled to a driving source; a following lever engaged with this driving lever and following this driving lever; and a rack rod engaged with the following lever and moving linearly. A first shaft and a link gear of the following lever are engaged with this rack rod. Moreover, by the driving lever and the following lever revolving under driving action of the driving source, a second shaft engaged with the link gear rotates, and the first shaft rotates via the rack rod.
