DEVICE FOR ENGINE RPM RESTORATION

摘要

PURPOSE: A device for restoring the engine RPM of heavy equipment is provided to improve the durability of equipment by reducing an engine load generated during a work. CONSTITUTION: A device for restoring the engine RPM of heavy equipment comprises a hydraulic pump, a main control valve(5), and a fuel supply unit(10) for preventing a load. The hydraulic pump is powered by an engine. The main control valve controls the flowing direction of operation pressure supplied from the hydraulic pump. When the operation pressure is over set-pressure, the fuel supply unit increases the amount of fuel in proportion to the operation pressure by pulling an acceleration cable connected to a throttle valve.
