ABSTRACT:
A control apparatus has a single control handle, first and second work elements, and first and second ramps each contacting a respective work element. Apparatus is further provided for selectively, progressively pivoting only one of the ramps in response to controllably moving the single control handle. One of the ramps pivotally moves in response to moving the handle in a first plane to a first position and in a different second plane from a first toward a second position. The other ramp pivotally moves in response to moving the handle in the first plane to a second position and in a different third plane from a first toward a second position. Respective work elements are thereby moved between a plurality of positions for controlling an operation such as the flow of fluid through associated, respective valves.
