A damper assembly exploiting a crankshaft to induce displacement of a damper means from one position to another.

Damper assembly exploiting a crankshaft

An air handling system for an indoor space comprising a first forced indoor air treatment component, an input indoor air duct element and an output treated air duct element respectively coupling said first forced indoor air treatment component to said indoor space, a second forced air treatment component a stale air duct element coupled to said second forced air treatment component and to said input indoor air duct, a return air duct element coupling said second forced air treatment component to said output treated air duct element characterized in that said system comprises a secondary air path means for coupling said return air duct element to said input indoor air duct element.

Pressure equilizing system

A damper assembly, comprising an adjustable locking means for releasable retention of an element pivotally in one of a plurality of predetermined lock positions for adjusting air flow through an opening.

Adjustable damper assembly

A coupling release component for releasabley coupling a shaft of a motor to a further shaft for rotation of the further shaft by the motor shaft having a rotation lock component having an axially disposed first gripping device for connecting the lock to the shaft for inducing rotation of said lock by said motor, a slip coupling component having a second gripping component disposed radially outwardly relative to the first gripping component configured to releasabley interlock with a corresponding third gripping component of a further coupling component for connecting the coupling release component to said further shaft for the rotation thereof and a resilient mounting component mounting said second gripping component to said first gripping component so as to be able to exert a radially outward force on the second gripping component so as to radially bias the second gripping component into interlocking engagement with the third gripping component.
