Fluidic transmission controller

摘要

A transmission controller that includes a series of fluidic comparators receiving power signals from selected ports in a manually-actuable range selector valve. Hydraulic signals representing engine throttle position and transmission output speed are beamed against each comparator main flow stream to switch the flow between a primary collector port and alternate collector port. Comparator outputs are amplified and applied to the end faces of spool valves that provide hydraulic actuator force for the transmission clutches.
