A system for controlling movements of doors of an HVAC module includes an actuation gear and an intermediate cam. A main door includes a first portion and a second portion having a first guide. The first portion engages with actuation gear to enable linear movement of the main door. A slave door includes a second engagement element and moves between a blocking and unblocking position based on movement of main door. The intermediate cam moves angularly and includes a first engagement element and a second guide. The first engagement element interacts with the first guide, and the second guide interacts with second engagement element to facilitate angular movement of slave door in response to movement of the main door. The first guide includes a bend positioned to enable angular movement of the slave door after the main door moves a pre-determined distance.

To improve a view of a side area from a cabin, the cabin mounted on a machine body includes a hollow rear pillar located on a rear portion of a side surface of the cabin. The rear pillar includes an interior opening through which an interior of the rear pillar is communicated with an interior of the cabin, and an exterior opening through which the interior of the rear pillar is communicated with an exterior of the cabin.

A heating, ventilation, and air conditioning (HVAC) airflow distribution module including a passenger side face outlet and a passenger center face outlet both defined by the module. A passenger face door sub assembly within the module includes a passenger side face door (outer portion) at the passenger side face outlet and movable to control airflow through the passenger side face outlet. A passenger center face door (inner portion) is at the passenger center face outlet and is movable to control airflow through the passenger center face outlet. The passenger side face door and the passenger center face door are movable independent of one another to independently control airflow through the passenger side face outlet and the passenger center face outlet.

An air conditioning damper includes a damper main body provided in a casing and closing a flow path formed in the casing by a distal end portion abutting against the inner surface of the casing. The air conditioning damper closes or opens the flow path by pivoting. The air conditioning damper has a cover portion provided on front surface sides or back surface sides of a plurality of protruding portions and extending in the width direction of the damper main body beyond a side surface of the protruding portion.

A heating, ventilation, and air conditioning (HVAC) airflow distribution module is integrated with a driver-focus mode operation mechanism for a vehicle. The module utilizes: a driver face door to control airflow through driver face outlets; a passenger face door sub assembly to control airflow through a passenger center face outlet and a passenger side face outlet independently; a foot door sub assembly including a passenger front foot door and a main foot door to control airflow through a passenger front foot outlet independently from driver front and rear foot outlets and a passenger rear foot outlet; and a separator to separate airflow through passenger front and rear foot outlets. The present disclosure enables an HVAC airflow distribution module to focus airflow on the driver's seat and maintain the vehicle recirculation at a comfortable level when no passenger is present.

A ventilation device may include first and second supply ducts, a mixing section having a mixing duct into which the first and second supply ducts may lead, the first and second supply ducts arranged in the mixing section adjacent one another in a transverse direction, and first and second guides in the mixing section each running in the transverse direction and being located opposite one another in a longitudinal direction running transversely to the transverse direction, each guide having two guide walls running in the transverse direction and located opposite one another in a height direction running transversely to the transverse direction and longitudinal direction, at least one of the guide walls sloping away from the other guide wall at a slope angle with respect to the longitudinal direction. A valve may have a plate body and may be adjustably guided with a first guide section running in the transverse direction in the first guide and with a second guide section running in the transverse direction in the second guide. 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 heating, ventilation, and air-conditioning system for a vehicle includes a housing, a door supported by the housing, and a lock integral with the housing. The housing further includes a first air flow path and a second air flow path. The door moves between a first position blocking airflow from the first air flow path and a second position blocking airflow from the second air flow path. The lock is configured to automatically lock the door in the second position upon assembly of the housing.

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.

A valve, in particular for an air duct of an air conditioning system of a motor vehicle, having a body and having at least two bearing couplings for bearing-mounted arrangement of the valve, wherein the body has a planar extent with a first side face and with an opposite second side face, wherein the first side face is convex in design.

A vehicle air-conditioning device may achieve comfortable heating of a vehicle interior by starting a compressor, an indoor blower and heat generating means at appropriate timing. The vehicle air-conditioning device includes a compressor which compresses a refrigerant, a radiator disposed in an air flow passage to let the refrigerant radiate heat, a heat absorber which lets the refrigerant absorb heat, and an indoor blower which blows the air through the air flow passage. The vehicle interior is heated by heat radiated from the radiator. The vehicle air-conditioning device includes a heating medium-air heat exchanger of a heating medium circulating circuit disposed in the air flow passage to heat air supplied to the vehicle interior. On a basis of an outdoor air temperature, the timing to start the compressor, the indoor blower and the heating medium circulating circuit is controlled.
