Abstract
A valve member is mounted on a shaft to pivot within a fluid passage. A control selectively moves a piston in a linear direction to control a position of the valve member in the fluid passage. The piston causes a roller pin to move as the piston moves linearly. The roller pin is mounted in crank collars of a crank shaft such that movement of the roller pin causes the crank collars to rotate crank shaft rotating position, and the valve shaft. The roller pin is mounted within the crank collars by bearings. The bearings each have an outer race associated with a crank collar, an inner race associated with the roller pin, and bearing members separate the inner and outer race. There is a spring bias resisting movement of the inner races relative to said roller pin. An anti-ice system is also disclosed.
