Claims

[Claims for Utility Model Registration] 1. A piston rod 8 having a pole nut 9 fixed to the open end of a hollow portion 8a having an open upper end is located at one side of the hydraulic cylinder 6 in communication with a pressure oil intake port 6a. The recess 6C provided on the upper surface of the hydraulic cylinder 6 is pressed by the return spring 13 toward the
The hydraulic cylinder is installed at the lower part of the rotary nozzle body 12, which is rotatably supported by the rotary nozzle body 12 and has a nozzle spout 12a that spouts the pressure oil introduced into the recess 6C from the pressure oil intake port 6b upward. Bearing 11 provided on the top of 6
Bowls and cru 10 rotatably supported by
are firmly connected to each other, the pole screw 10 is screwed to the pole nut 9, and the hydraulic cylinder 6
A motor reflex valve having a pressure oil return port 7a which is attached to the upper part of the motor frame and which returns the pressure oil ejected from the nozzle outlet 12a. - The guide groove 3 is rotated by the spring 4 installed in the guide groove 3a bored in the lower surface of the housing 3, which is rotated by the pulse motor 1 fixed to the housing 3.
A plate 5 that can freely go in and out of the rotary nozzle body 1
A pulse-driven single-acting actuator characterized in that it is pressed into a state where it can closely slide on the nozzle outlet 12a of the second nozzle. 2 Plate 5 and nozzle/U spout 1 of rotating nozzle body 12
2a. The pulse-driven single-action actuator according to claim 1, which is a utility model registered. 3 Utility model registration claim 1 in which the piston rod 8 is moved forward within the hydraulic cylinder 6 due to an increase in hydraulic pressure
The pulse-driven single-acting actuator according to item 1 or 2. 4 Utility model registration claim No. 1 in which the piston rod 8 is retracted within the hydraulic cylinder 6 due to an increase in hydraulic pressure
The pulse-driven single-acting actuator according to item 1 or 2.
