Force multiplying control cable system

A control system for use in an HVAC unit comprises a circular pulley (22), a semi-circular pulley (28), and a cable (30) interconnecting the pulleys (22, 28) to rotate a spur gear (32). A flange (44) extends about the periphery of the semi-circular pulley (28) and pulley gear teeth (70) extend radia...

description A control system for use in an HVAC unit comprises a circular pulley (22), a semi-circular pulley (28), and a cable (30) interconnecting the pulleys (22, 28) to rotate a spur gear (32). A flange (44) extends about the periphery of the semi-circular pulley (28) and pulley gear teeth (70) extend radially inwardly from the flange (44) and engage the spur gear teeth (60). The spur gear (32) is rotatably supported on a gear shaft (62) which extends through a slot (64) in the semi-circular pulley (28) that extends arcuately between two slot ends (66). The slot (64) is spaced radially between the flange (44) and a support shaft (45) of the semi-circular pulley (28) thereby allowing the semi-circular pulley (28) and the spur gear (32) to overlap to attain compact packaging of the system.
