Patent ID: 7490626

Claim:
A controller operable to control the flow of fluid from a source of pressurized fluid to a first fluid pressure actuated device; said controller being of the type including housing means defining an inlet port for connection to the source of pressurized fluid, a return port for connection to a system reservoir, and first and second control fluid ports for connection to said first fluid pressure actuated device; a valve means disposed in said housing means with said valve means defining a neutral position ( FIG. 5 ) and a first operating position ( FIG. 6 ); said valve means and said housing means cooperating to define a main fluid path communicating between said inlet port and said first control fluid port, and between said second control fluid port and said return port when said valve means is in said first operating position; a fluid actuated means for imparting follow-up movement to said valve means proportional to the volume of fluid flow through said fluid actuated means; characterized by: (a) a second fluid pressure actuated device the displacement of which is representative of the displacement of said first fluid pressure actuated device when said valve means is displaced from said neutral position to said first operating position; (b) a second fluid path communicating between said fluid actuated means and said second fluid actuated device; and (c) said second fluid path being separate from said main fluid path.
