An air mixing damper arrangement having a first cooled air damper damping cooled air in a cooled air flow path and a second heated air damper damping heated air in a heated air flow path, wherein the first damper has a first shaft having a first center of rotation and the second damper has a second shaft having a second center of rotation, wherein the first center of rotation and the second center of rotation are substantially identically aligned. The first damper and the second damper are individually rotatable about their respective center of rotation, wherein the first damper and the second damper are both actuated by a cam plate, the first damper has a lever having a pin having a top level shape and a bottom level shape, the second damper has a lever having a first pin and a second pin.

Air mixing damper arrangement

An actuator consists of a pair of compact cam plates with compound straight and semicircular toothed racks that engage a single circular gear turned by a single motor. As the gear turns in one direction, the cam plates are pulled toward one another in a guided straight line until they engage and lock around the gear. Continued turning of the gear rotates the locked cam plates with the gear. The motion is reversed as the gear reverses.

Combination linear and rotary actuator

Each generic gear includes one tooth disposed in each of the sockets, and each tooth extends radially outward from one of the sockets and throat thereof. The teeth of the generic gear include resilient material adjacent the throat for compressing and allowing movement of each tooth relative to the outer periphery. In the species of FIG., each tooth is entirely of the resilient material and diverges or circumferentially widens from adjacent the throat to define a gap from the throat to the outer periphery. In the species of FIG., each tooth has a shell integral with the hub and a core of the resilient material fills each shell and extends into the socket to define a crescent-shaped gap with the socket end.

Zero backlash gearing

An anti-backlash assembly of the type for transferring motion via a pin movable along a slot. The assembly comprises a pivot lever and a second lever member. The pivot lever comprises a body portion and a pivot lever portion extending from the body portion to a pivot lever distal end. The pivot lever portion defines a pin engagement slot extending from adjacent the pivot lever distal end toward the body portion. A pair of fingers extend in parallel and spaced relationship from the pivot lever distal end of the pivot lever portion toward the body portion to engage opposite sides of a pin of the engagement arm. Each of the fingers includes a pin engaging section extending to an inwardly extending distal end and a spring section extending in a for urging the fingers into clamping engagement with the pin.

Anti-backlash/anti-rattle lever

An HVAC controller housing including a plurality of valves extending therein for directing airflow to a plurality of ducts is provided. The housing is of the type including a side port extending outwardly from the housing and in fluid communication with one of the ducts. A drive gear is provided on the housing to drive a plurality of driven gears disposed on the housing for driving the plurality of valves. The driven gears are responsive to the drive gear through a transmission member comprising an annular idling gear in meshing engagement with the drive gears and at least one of the driven gears. The annular idling gear is rotatably supported on the housing and encircles the side port for efficient torque transfer between the drive gear and the driven gears.

Mode mechanization system with integrated heater outlet

A valve including a film having edges and a plurality of openings disposed between the edges is supported by the housing of an automotive a heating, ventilation and air conditioning system to control the flow of air blown into the passenger compartment. The film has recesses along both edges. The film is reciprocated along the curved path by a first pair of sprockets supported on a shaft and presenting first axial teeth engaging the recesses along the edges of the film (FIGS.-), or a second pair of sprockets having first radial teeth engaging the recesses in the edges of the film and driven from the shaft by bevel gears (FIGS.-), or third pair of sprockets having second radial teeth engaging the recesses in the edges of the film and driven by a spur (FIG.), or by the spur directly engaging the recesses in the edges of the film (FIG.).

Sliding film valve driven at edge

An improved vehicle heating and air conditioning system includes a driver-manipulated temperature selector that is physically coupled to a discharge temperature control mechanism. The selector is operable in a normal mode in which movement of the selector away from a full cold setting produces a corresponding movement of the temperature control mechanism that increases the discharge air temperature by re-heating or a high fuel efficiency mode in which movement of the temperature selector away from the full cold setting allows the temperature control mechanism to remain in a full cold position for a limited range of selector movement while the discharge air temperature is increased by capacity reduction of the refrigerant compressor. The temperature selector is in the form of a rotary knob that is axially shiftable to change modes when the selector is positioned at the full cold setting and spring-biased so that the normal mode is established as the default mode.
