FIELD: mining.
SUBSTANCE: present group of inventions can be used for high-speed hydraulic actuation. Device and method for high-speed hydraulic actuation. Method includes adjusting a position of an actuator using a hydraulic pressure regulator and pressure sensing line, which moves the hydraulic pressure regulator into the static position due to pressure created at the inlet opening for counter pressure. Adjusting the position of the actuator includes increasing pressure on the hydraulic pressure regulator to open the actuator using a first solenoid, or decreasing pressure on the hydraulic pressure regulator to close the actuator using a second solenoid.
EFFECT: to increase the reliability of hydraulic actuation.
