HYDROMECHANICAL SPEED REGULATOR Russian patent published in 2003 - IPC

FIELD: transport machine engineering. SUBSTANCE: hydroautomatic mechanical power transmission includes regulator, two gate type positive-displacement mechanisms arranged one inside another. Output shaft-rotor of one mechanism serves as housing for another one. Input shaft-rotor is joined with motor; output shaft-rotor is joined with propeller. Regulator is centrifugal one and it is arranged inside output shaft-rotor. Gate valves are mounted in housing with possibility of controlled forcing to output shaft-rotor. EFFECT: simple design of convenient in operation hydroautomatic mechanical transmission having high efficiency. 3 dwg _
