Abstract:
A heating, ventilation and air conditioning assembly for mounting to a housing, the motor assembly comprising:a motor having a generally cylindrical portion and a connector extending from said cylindrical portion, said motor having an air flow passage therethrough,a one-piece cover structure comprising:a generally cylindrical section having an opening at one end thereof and a closed end opposite said one end, and an interior between said ends, said motor being disposed in said interior so that one end of said motor is covered by said closed end,a flange structure extending from said cylindrical section,a first passage having an open end and being in communication with said interior, said first passage communicating with a connector opening in said cover structure, said first passage being sized to permit said connector of said motor to pass therethrough and said connector opening receiving said connector, said connector opening being sized to fit tightly with said connector to substantially prevent air from passing between said connector and said cover structure, anda second passage in open communication with said interior and in communication with said air flow passage of said motor so that air may enter said second passage and exit through said air flow passage to cool said motor, anda vibration damping member between said cylindrical portion of said motor and said cylindrical section of said cover structure so as to contact said cylindrical portion and said cylindrical section to dampen vibration of said motor,wherein said first passage is defined in part by a tapered surface which leads to said connector opening and said connector has a tapered surface such that when said motor is inserted into said cover structure, said tapered surface of said connector rides on said tapered surface of said first passage until said connector enters said connector opening.
