<p>A single lever control arrangement for selectively actuating a pair of first and second valve spools reciprocally mounted in a housing comprises a handle assembly including a triangular plate pivotally mounted on the housing by a first ball and socket connection. The first and second valves are pivotally mounted to the plate by second and third ball and socket connections, respectively, whereby the valves may be reciprocated by the handle assembly separately or simultaneously.</p> |
