ABSTRACT:
A throttle control that provides accurate and reliable control for a plurty of remote air driven devices. The throttle control employs a plurality of primary valves that are built into a common body with a handle and a plurality of operating levers. The body has a single air supply port which directs air through a common chamber to all of the primary valves. In the body are formed a plurality of separate chambers that communicate the outlet air from the plurality of respective primary valves to the plurality of air conduits to supply air to the respective air driven devices. The handle has a chamber through which exhaust air has a tortious flow path to atmosphere. Each primary valve employs an air control valve and an air vent valve that are sequentially actuated by the associated operating lever. When the lever is not depressed, the control valve is closed and the vent valve is open and vents the air in the supply conduit through the handle chamber to atmosphere. Oil or other droplets are separated from the vented air by the tortious flow and are collected in the handle chamber. As the lever is depressed, first the air vent valve is closed and then the air control valve is gradually opened to supply air to the air driven device. The reverse takes place as the lever is released.
