Abstract
Disclosed is an anti-rattle valve feature for a heating, ventilating, and air conditioning assembly. In a typical HVAC assembly each end of an air valve shaft is received in a pivot hole permitting the air valve shaft to rotate within the assembly. Because the inside diameter of the pivot holes are larger than the outside diameter of the ends of the air valve shaft, the air valve shaft may rattle within the pivot holes. Disclosed is a finger that contacts the air valve shaft to apply pressure to the air valve shaft and biases an end of the air valve shaft against the inside of it pivot hole, thereby preventing rattling of the air valve shaft within its respective pivot holes.
Claims23
A heating, ventilating, and air conditioning assembly comprising:
- a housing having a first pivot hole with an inside;
- an air valve shaft having a first pivot point, said first pivot point received in said first pivot hole and rotatable therein;
- and
- a finger, said finger contacting said shaft and biasing said first pivot point against said inside of said first pivot hole thereby reducing a rattle of said air valve shaft.
A heating, ventilating, and air conditioning assembly comprising:
- a housing having a first pivot hole with an inside and a second pivot hole with an inside;
- an air valve shaft having a first pivot point opposite a second pivot point, said first and second pivot points received in said first and second pivot holes, respectively, and rotatable therein;
- a first finger, said first finger contacting said shaft and biasing said first pivot point against said inside of said first pivot hole;
- and
- a second finger, said second finger contacting said shaft and biasing said second pivot point against said inside of said second pivot hole, said first and second fingers reducing a rattle of said air valve shaft.
