SPEED-SAVER Top Speed Controller for Cable Type Accelerators

SPEED-SAVER Automatic top speed controller for IC vehicles with conventional accelerator cables

Gear tooth speed sensor that is to be installed in axle differential to read gear speed
Controller with indicator LEDs and adjustment pots
Electronic motor actuator "arm"
Cable or rod connecting "arm" to throttle lever on engine (includes brackets and connectors). Amount of throttle restriction is done on adjusting nut at throttle connection

Controls vehicle top speed WITHOUT effecting engine RPM at low travel speed
Therefore the device does NOT effect low speed power necessary for heavy hydraulic lifting operations.

When the vehicle reaches "actuation" speed – (approximately 3 mph) device's "arm" actuates - pulling back cable connected to throttle lever--restricting it's stroke.
The throttle lever stroke is restricted - which controls top speed - driver can push hard on accelerator but not increase engine RPM
When the vehicle speed is reduced below "actuation" speed - the "arm" relaxes and the engine throttle again has full stroke (full power) ---with NO restriction.
