Abstract
A cam actuated valve (10) is disclosed having a butterfly-type valve member (52) rotatably mounted to a crank member (40) extending into a fluid passageway (23) defined by the valve housing. A rectangular bracket (12) attached to one side of the valve housing has parallel edges (66, 68) forming guide surfaces which are slidably received in parallel grooves (62, 64) molded into an actuator member (14). The outer end of the crank member extends through an elongated slot formed in the actuator member thereby defining a cam-cam follower arrangement which transfers the linear movement of the actuator member to rotation of the crank member. The configuration of the cam slot and its position relative to crank member follower end provides a mechanical advantage enabling a relatively low input force exerted on the actuator member to operate the valve.
