Abstract: An air-conditioning duct for vehicles with one duct mutually connected and fixed to the other duct is provided. One duct is formed by incorporating a first unit duct with a flange formed around an opening periphery thereof and a second unit duct with a flange formed around an opening periphery thereof in parallel. The other duct is formed by incorporating a third unit duct with a flange formed around an opening periphery thereof and a fourth unit duct with a flange formed around an opening periphery thereof in parallel. The flange formed on the boundary side of the second unit duct are fixed with one over another, and the flange formed on the boundary side of the third unit duct and the flange formed on the boundary side of the fourth unit duct are fixed with one over another.

Abstract: An HVAC damper includes a sheet metal frame surrounding a series of pivotal damper blades that are each supported by a pair of plastic bearing members. Each bearing member is a unitary piece that includes a radial bearing, a thrust bearing, a lug for connecting to a damper blade, a shaft-receiving feature for connecting to a drive shaft, and multiple crank pins for selectively connecting to a drive linkage. Choosing which crank pin gets connected to the linkage determines a damper blade's rotational direction relative to the other damper blades. Adjacent damper blades preferably rotate in opposite directions to ensure positive sealing engagement between their adjacent blade tips. The bearing members allow the drive linkage to be installed outside the frame to avoid obstructing the airflow through the damper. During assembly, the bearing members allow the damper blades to be placed within the frame prior to installing the bearing members.

Abstract: A damper device includes a first baffle capable of opening or closing a first opening portion by turning about its axis and a second baffle capable of opening or closing a second opening portion by turning about its axis. A common drive source for driving the first baffle and the second baffle and a gear train by which the output from the drive source is transmitted to the first baffle and the second baffle are also provided. The device also includes a first rotary shaft driven by the gear train for driving the first baffle and a second rotary shaft driven by the gear train for driving the second baffle. The first rotary shaft and the second rotary shaft are arranged to be extended from the positions adjacent to each other on the gear train toward one side in an axial direction of the gear train.

Abstract: A vehicle air conditioning apparatus having two pair of rotatable flow control doors for separately controlling and varying the temperature and flow of air supplied to two different zones of the vehicle interior. Each pair of flow control doors are linked together and operated by a single actuator device.

Abstract: An air flow control register includes a frame carrying pivotable vanes, which are rotated on parallel axes by a common drive mechanism, so that the setting of the vanes is variable between a maximum flow position, in which the flaps have a minimum inclination with respect to the direction of air flow through the register, and a no-flow position in which this inclination is a maximum. The drive mechanism controls the pivoting of the vanes in such a way that they all rotate by the same amount, with alternate vanes rotating in opposite directions.

Abstract: An opposed louver air damper apparatus for controlling the flow rate of combustion air to a burner fire box, comprising a plurality of adjacent, rotatable louvers having rubber tips and side gaskets providing sealing between the louvers and a frame, and geared responsive shafts supporting the louvers for controllably rotating the louvers to determinative positions to modulate the volume of air passing through the louver apparatus, wherein the gears in meshing engagement precisely maintains the relative position of the louvers, and the gaskets operate to minimize undesirable leakage through the air damper. The gears form teeth in arcuate portions of the full circumference to limit the rotational movement to only that within the toothed portion of the gear.

Abstract: An actuator assembly for a multi-blade damper includes a base plate having slots extending longitudinally thereof and slidably receiving drive portions of the louver shafts. A series of drive slots extending generally perpendicular to the clearance slots is formed at each side of the clearance slots. A series of link assemblies are keyed to the shafts, the link assemblies including actuator pins extending into selected ones of the drive slots. A clamp connection interposed between the link and drive portion of the louvers permits relative adjustment of the link relative to the louver. Movement of the base plate parallel to the plane defined by the axes of the louvers results in tilting of the louvers in a selected direction, dependent upon which of the series of drive slots is occupied by a pin of a respective link.

Abstract: A damper control system which employs an unsheathed cable to transmit torque from a torque inducing tool to a damper regulator for regulating a damper of an air processing system. The damper control system has a first cable bracket with a first bracket passage through which the unsheathed cable passes. The first cable bracket is designed to be affixed to a surface accessible to the torque inducing tool. Longitudinal motion of the unsheathed cable with respect to the first cable bracket is limited by a pair of first bracket clips attached to the unsheathed cable and positioned such that the first bracket passage is interposed therebetween. The unsheathed cable is provided with a first cable end which can be engaged by the torque inducing tool and a second cable end which is either permanently affixed to or can be maintained slidable engaged with the damper regulator.

Abstract: The air lock includes a frame, a passage port defined by the frame, a plurality of side by side tabs supported in a rotating manner by the frame and extending through the passage port as well as kinematic connections between the tabs to ensure simultaneous and synchronized movement of each of said tabs between a closed position wherein all the tabs are essentially coplanar and close the passage port and an open position rotated by approximately 90.degree. in relation to the closed position. The air lock is characterized in that each tab is supported by the frame by at least one supporting plate separate from the frame and inserted in a pair of tracks formed in the frame and in that the kinematic connections are housed in a space made in the frame and enclosed by the tab supporting plates.

Abstract: A damper assembly gear system for interchangeably carrying either airfoil damper blades or single-ply damper blades. A first embodiment, in which the damper blades rotate in opposition to one another, includes a group of gear bodies, each of which includes a tab structure, including both airfoil tabs and single-ply tabs, for mounting both types of damper blades. The airfoil tabs are shaped to match an airfoil damper and are spaced apart such that an airfoil damper can be inserted between and gripped by the airfoil tabs. Single-ply tabs are located between the airfoil tabs, shaped to match a single-ply damper and spaced apart such that a single-ply damper can be inserted between the single-ply tabs and gripped thereby. An alternative embodiment allows the system to be used in conjunction with both opposed and parallel damper assemblies. First, this embodiment includes two types of gears, blade gears and idler gears.
