Abstract
PURPOSE: To produce high fluid pressure without need of great tread force by conducting a large diametral cylinder chamber to a small diametral cylinder chamber through a valve which closes according as the fluid pressure in the small diametral cylinder chamber grows to be more than a settled value.
CONSTITUTION: Passages 37, 38 and a chamber 39 are provided on the first piston member 8 and a passage 41 is provided on a plug member 40 fixed on the first piston member 8, while at the same time a large diametral cylinder chamber 16 is conducted to a small cylinder chamber 17 through these passages 37, 38, 41 and chamber 39, a valve element 43 is provided in the dhamber 39 for the purpose of closing the passage 38 as fluid pressure in the small diametral chamber 17 grows to be more than a settled value. Thus, according as the fluid pressure in the small diametral cylinder chamber 17 grows to be more than a settled value, the fluid pressure only in the small diametral cylinder chamber 17 results in continuously going up, so that high fluid pressure can be produced without need of great tread force.
