HYDRAULIC SERVOAMPLIFIER Russian patent published in 2004 - IPC

FIELD: applicable in the control systems, can be used in control of transport vehicles. SUBSTANCE: the servoamplifier has a body with discharge and exhaust chambers separated by a piston conjugate to the controlled mechanism and having a discharge channel, and a control rod located in the discharge chamber of the body coaxially with the piston that in its turn is conjugate to the control member and forming jointly with the discharge chamber of the piston a "nozzle-flap" pair, as well as an overflow valve having a spring-loaded shut-off member. The spring-loaded shut-off member of the overflow valve is installed in the axial channel of the control valve communicating with the discharge chamber and made on the side of the discharge channel. EFFECT: enhanced reliability and no-failure operation at a simplified construction, reduced overall dimensions and mass. 1 dwg
