The present invention relates to a cam-operated device (5) for controlling at least one component, said device comprising a cam (6) comprising at least one first camway (7, 8) on a first face and a second camway (9) on an opposite face, said first camway (7, 8) having a depth, measured starting from an opening, at the level of said first face, of said first camway, and said second camway (9) having a depth, measured starting from an opening, at the level of said opposite face, of said second camway, a height of the cam (6), measured between the opening of the first and second camways, being less than the sum of the depths of the camways (7, 8, 9).

A rotary apparatus includes a motor, a plurality of gears including an output gear, and a housing accommodating the plurality of gears and the motor. The housing includes a first surface portion, a second surface portion facing the first surface portion and spaced apart from the first surface portion, and a sidewall portion provided at an outer peripheral portion of the first surface portion and the second surface portion and supporting the first surface portion and the second surface portion. One of the first surface portion and the second surface portion includes a vibration damping part opposing the output gear.

The present disclosure provides a power transmission device in which stress is reduced and a vehicle air-conditioning device. An air-conditioning device has an inside/outside air door. A power transmission device drives the inside/outside air door. The power transmission device has a motor, a gear train, and a cam mechanism. A first gear of the gear train provides a rotatable member. A plurality of lock mechanisms is provided, which stops a rotation of the first gear at one end and/or the other end in a rotation direction of the first gear. The plurality of lock mechanisms provide a plurality of contacts between the first gear and a stationary link cover.

An air conditioner has: an air-conditioning case including an air passage; a plate-shaped door body that rotates about a rotation shaft; and an opposing wall provided in the air passage to define a gap between a tip portion of the door body and the opposing wall. A length of the opposing wall in a circumferential direction of the rotation shaft is larger than a thickness dimension of the tip portion of the door body. The opposing wall includes a first door facing surface and a second door facing surface. The air-conditioning case has a connecting surface connecting the first door facing surface and the second door facing surface. The second door facing surface is located outward with respect to the rotation shaft in a radial direction than the first door facing surface is.

A HVAC system for a motor vehicle having a housing, wherein the housing has an air inlet for admitting air and a cold air path in which cold air flows is provided in the housing and a warm air path in which warm air flows is provided in the housing, wherein the warm air path and the cold air path open into a mixing chamber, wherein a mixing flap is provided for controlling the proportion of cold air flowing into the mixing chamber and the proportion of warm air flowing into the mixing chamber, wherein the mixing flap is arranged rotatable about an axis and is driven by a flap actuator which has a drive shaft, wherein a gear with a nonlinear translation characteristic is provided between the mixing flap and the drive shaft.

A lever for an air vent assembly. The lever includes a first arm and a second arm, each extending from a base portion creating a guiding path therebetween. The first arm includes a first portion having a curved profile to facilitate abutment of the first portion with a movable disc of the assembly. The lever has a flexible third arm extending from the base portion and configured substantially parallel to the second arm. This shape and/or material of the third arm facilitates smooth and constant abutment of the first portion with the movable disc, and ensures a soft contact of the first lever against an inner surface of a housing of the assembly.

A motor vehicle air-conditioning line valve arrangement includes a line valve having an air-conditioning line body which is of substantially closed design in a transverse plane, and a fiber nonwoven arranged on an inside in the air-conditioning line body and having a nonwoven mat to which a large number of nonwoven fibers are fixed. The nonwoven fibers are fixed to the nonwoven mat at one end and configured to be electrostatically charged by the nonwoven mat. An electrical charge generator is electrically connected to the nonwoven mat and configured to electrostatically charge the fiber nonwoven, so that the electrostatically charged nonwoven fibers straighten toward a center of the air-conditioning line body in such a way that they close an open flow cross section of the air-conditioning line body.

The present invention relates to an air conditioner for a vehicle, which can improve a gear ratio of a power transmission means in order to operate a sliding door with more torque. The air conditioner for a vehicle includes: an air-conditioning case having a heat exchanger; a first door and a second door disposed inside the air-conditioning case to adjust the degree of opening of an air passageway; a first driving part for operating the first door; a power transmission part connected to the first driving part; a second driving part for operating the second door; and a third driving part for connecting the power transmission part with the second driving part.

A rotary apparatus includes a motor, a plurality of gears including an output gear, and a housing accommodating the plurality of gears and the motor. The housing includes a first surface portion, a second surface portion facing the first surface portion and spaced apart from the first surface portion, and a sidewall portion provided at an outer peripheral portion of the first surface portion and the second surface portion and supporting the first surface portion and the second surface portion. One of the first surface portion and the second surface portion includes a vibration damping part opposing the output gear.

A ventilation device may include a housing, a fluid channel system, a heat exchanger, and a slider arrangement. The slider arrangement may include at least one first slider and at least one second slider arranged within the fluid channel system upstream of the heat exchanger and downstream of the heat exchanger respectively. The first and second slider may be guidable transversely with respect to at least one fluid flow. The first and second slider may each be actuatable via a respective pinion shaft. At least one of a volume flow and a mass flow of at least one fluid flow may be at least one of controllable and regulatable via actuation of the first slider. At least one of a predetermined fluid temperature and a predeterminable fluid temperature of a mixed fluid may be settable and at least two fluids may be mixable via actuation of the second slider.
