Abstract
A rotary valve actuator for actuating a valve pivotally disposed in a housing and movable between first and second positions. The actuator includes an actuator member coupled to the valve, a resilient arm coupled to one of the housing or the actuator member, and a wall member protruding from the one of the housing or the actuator member to which the resilient arm is not coupled. An arm tab protruding from the resilient arm is aligned with and preferably protrudes through an opening of the wall member when the valve is in the first position, and an arm engagement member of the resilient arm is engaged with a wall engagement portion of the wall member when the valve is in the first position. The resilient arm is flexible away from the wall member to disengage the arm engagement member from the wall engagement portion. The actuator is operable remotely by one or more flexible straps coupled to the actuator member.
