きるのである。Function In the above configuration, the on-off valve is periodically opened and closed by the valve driving means, and fluid is supplied from the supply pipe. When the on-off valve opens, fluid flows into the large-diameter cylinder and flows from the communication pipe into the small-diameter cylinder via check-1t. The total pressure acting on the large diameter screw 1 is equal to the small diameter screw 1.
Since the pressure is greater than the total pressure acting on the piston surface, the large diameter screw 1 resists the compression spring and is forced through the piston spigot into the small diameter screw 1.
Press the button to compress the inside of the small diameter cylinder. This increases the pressure of the fluid in the small diameter cylinder in inverse proportion to the cross-sectional area of both cylinders, flows into the delivery pipe via the check valve and is used at the end of the delivery pipe, or stored in a tank. Furthermore, when the on-off valve closes, the supply of fluid from the supply pipe is stopped, and the compression spring uses its restoring force to push the large-diameter piston in a direction that compresses the inside of the large-diameter cylinder. As a result, the fluid in the large-diameter cylinder flows backward through the supply pipe and flows into the small-diameter cylinder from the communication pipe via the check valve. Subsequently, when the on-off valve opens, the same operation as above is repeated. In this way, it is possible to increase the pressure of the fluid in the delivery pipe only by opening and closing the on-off valve without increasing the pressure of the fluid in the supply pipe.

When the solenoid valve 9 opens, a part of the fluid flows into the large diameter cylinder 2, and The remaining part is connected to the small diameter cylinder 3 via the check valve 12 from the communication pipe 11.
flow inside. Since the cross-sectional area A of the large-diameter cylinder 2 is larger than the cross-sectional area A2 of the small-diameter cylinder 3, the large-diameter piston 4
The total pressure acting on the piston surface of is greater than the total pressure acting on the piston surface of the small diameter piston 5. Therefore, the large-diameter piston 4 pushes the small-diameter piston 5 via the piston rod 6 against the compression spring 7, and compresses the inside of the small-diameter cylinder 3. As a result, the pressure of the fluid in the small diameter cylinder 3 is increased in inverse proportion to the cross-sectional areas A□ and A2 of both cylinders 2 and 3. That is, when the pressure inside the supply pipe 8 is Pl, the pressure P2 inside the small diameter cylinder 3 becomes P, A□/A2. The fluid in the small diameter cylinder 3 whose pressure has been increased in this way flows into the delivery pipe 13 via the check valve 14 and is used at the end of the delivery pipe 13, or is stored in the pressure tank 16. be done. Furthermore, when the solenoid valve 9 closes, the supply of fluid from the supply pipe 8 is stopped, and the compression spring 7 is moved to the large diameter cylinder 2 by its restoring force.
The large diameter piston 4 is pushed back in the direction of compressing the inside. As a result, the fluid in the large-diameter cylinder 2 flows backward through the supply pipe 8 and flows into the small-diameter cylinder 3 from the communication pipe 11 via the check valve 12 . Subsequently, when the solenoid valve 9 opens, the same operation as described above is repeated. In this way, only by opening and closing the solenoid valve 9, the delivery pipe 1 can be removed without increasing the pressure of the fluid in the supply pipe 8.
It is only possible to increase the pressure of the fluid inside 3.
