FIELD: mechanical engineering; devices for testing indirect-action speed governors for internal combustion engines. SUBSTANCE: stand has governor electric drive, variable-speed drive, hydraulic servomotor connected to inner oil system through control spool valve. The latter is coupled with governor output and piston of hydraulic servomotor through leverage. Novelty in design of device is that piston of hydraulic servomotor is connected to variable-speed drive installed between electric motor and shaft of drive of speed governor under testing. EFFECT: possibility of testing, adjusting and quantity evaluation of operation of speed governor provided with built-in speed setting device. 1 dwg
