Abstract: An independent mixing valve sub-assembly which includes a casing defining a cold bias inlet, a hot bias inlet and a second zone inlet and a mechanism for mechanically attaching the casing to the housing of a HVAC module with the cold bias inlet, the hot bias inlet and the second zone inlet of the mixing valve sub-assembly in sealing engagement with a cold bias outlet, a hot bias outlet, and a second zone outlet of a HVAC module, respectively. The mixing valve sub-assembly may provide one or more streams of temperature-controlled air. Accordingly, different mixing valve sub-assemblies may be attached to one universal HVAC module to provide varying numbers of temperature zones.

Abstract: The invention provides an isolator for isolating vibration associated with an electric motor. The isolator includes a first body portion operable to be positioned adjacent to an external surface of a motor case of the electric motor. The isolator also includes a tongue integrally formed with and narrower than the first body portion. The tongue is operable to be received in a groove formed in the motor case. The isolator also includes a second body portion integrally formed with and wider than the tongue. The second body portion is operable to be disposed adjacent an internal surface of the motor case. As a result, at least a portion of the motor case of the electric motor is disposed between the first and second body portions.

Abstract: A heating and air-conditioning (HVAC) module for an automotive vehicle wherein the electric motor for the blower includes a double walled motor housing for noise abatement. The housing defines a cup-shaped inner casing with an open end and a closed end. An outer casing surrounds and is integrally connected to the inner casing by an integral flange. The outer casing extends upwardly from the flange to a rim to define a space surrounding the inner casing. An end cap includes a groove to engage the rim and extends over and in spaced relationship to the closed end of the inner casing. The end cap is held in place by fasteners threadedly engaging posts extending upwardly from the flange, with one of the posts extending upwardly from a female electrical connector that extends radially between the outer casing and the inner casing for supplying electrical power to the motor.
