Cam Driven Fluid Valve Assembly

原文（中文）

A cam-driven valve assembly includes a valve housing that defines a plurality of fluid passageways and supports an array of sliding-gate fluid valves in the fluid passageways to control the flow of fluid therethrough. The assembly includes a plurality of cams supported on a cam shaft. The cam shaft is arranged so that each cam is associated with a corresponding sliding-gate valve. Rotation of the cam shaft results in actuation of the valves via the cams. Each cam includes a pair of cam disks that cooperate to define an internal cam track. A movable plate of each fluid valve includes a cam follower that is received in the cam track of a corresponding cam. The cam tracks may be configured such that at least one of the sliding gate valves is actuated at time that is different relative to an actuation time of another sliding gate valve.
