ABSTRACT:
A diverter valve and actuator assembly for diverting flow of a fluid from one path to another under the control of a power driven actuator, including a valve body having a chamber therein with an inlet port and two outlet ports, each outlet port having a valve seat therearound, a valve shaft extending through the body into the chamber, and a valve member carried by the valve shaft and disposed to be mated selectively with either of said valve seats by appropriate rotation of the valve shaft, and the assembly further including an actuator having a power driven shaft carrying a pivot which provides a reciprocatory component of motion with respect to the valve shaft when the actuator is driven. A control arm assembly is carried by the valve shaft and has two rigid arms extending from the valve shaft and a resilient leaf spring arm fixed with respect to the valve shaft and extending radially therefrom between the rigid arms and spaced therefrom, the end of the resilient arm being pivotally connected by a link to the reciprocating pivot, and the actuator overdriving the link beyond the motion required to move the valve member between the seats whereby the resilient arm is bent when the valve member is seated.
