MULTIPLE HYDRAULIC CONTROL
ABSTRACT OF THE INVENTION
A kit is used for converting a single outlet
hydraulic system to a multiple outlet system. The kit
includes plural two-way, two-position solenoid operated
valves, gauged with their inlets connected in parallel
and their outlets serving as the multiple outlets. The
valves are operated by a control handle mounted on the
control lever of the single outlet system. Each valve is
controlled by an independent switch on the hand grip of
the handle. The control handle can thus be used both to
select an outlet and to control the flow through the
outlet.
