Throttle locking device for a diesel engine
This patent describes a vehicle including a diesel drive engine, an engine compartment within which the engine is mounted, a driver compartment separate from the engine compartment, a fuel flow throttle control device mounted within the engine compartment for varying the amount of fuel fed to the engine so as to vary the rate of revolution thereof, a foot actuable lever mounted within the driver compartment movable to varying positions between a maximum and minimum position of the throttle control device, a linkage system connected to the throttle control device and movable in response to actuation of the lever. The linkage system includes an elongate rod, a clamp member mounted within the engine compartment the clamp member including a support member having an opening therethrough through which the rod passes and which constrains the rod to move in a direction longitudinal of the rod and a clamp body mounted on the support member and movable relative to the support member from a first position free from the rod in which the rod can freely move in the opening in response to actuation of the lever to a second position in which the clamp body engages the rod and presses the rod against a side of the opening so as to clamp the rod between the clamp body and the side to hold the throttle control device at a position between the maximum and minimum positions of the throttle control device. An air operated cylinder is mounted on the support member for moving the clamp body between the first and second position thereof and a switch is mounted within the driver compartment for selectively supplying operating air to the air operated cylinder.
