Abstract

PURPOSE: To make solenoid selector valves needless and to enable the use of heavy oil by composing an actuator of a rotary vane fixed on an output shaft and oscillated by hydraulic pressure, a rotary valve interlocked with the vane, and a control spool valve for controlling the vane and the valve.
CONSTITUTION: Of the oil flowing into an oil inlet 21 of an actuator 1, a first portion returns to an oil tank through an oil line 24, oil chamber 9, oil line 24', and oil line 14. A second portion of the oil flows into an oil chamber 10 through an oil line 25, to push a spool 11 toward a plug 5. A third portion of the oil flows into the space formed by a casing 4, rotary vane 34, and fixed vane 37 through an orifice 28, notch groove 44 of the spool 11, oil line 26, and oil line 35, to rotate the rotary vane 34 counterclockwise. By the operation of a rotary valve 19 interlocked with the rotary vane 34, the pressure relation between the chambers 9 and 10 is reversed, the spool 11 is pushed down toward a plug 7, and the rotary vane 34 rotates in the reverse sense.
