Abstract
PURPOSE: To obtain a fluid pressure cylinder having a miniature structure and a large pressure conversion ratio by a constitution wherein there are an actuating external drum and an actuating inner drum which cooperate with this external drum.
CONSTITUTION: An actuating external drum 10 is provided with an external drum circular ring 12 having an external drum bottom plate 14 and a central projection part 16 is errected from the bottom plate 14 toward the inside of the circular ring 12. The central projection part 16 is provided with a central circular pillar 18 and the 1st flange 20 of a disk type installed at the left end of the pillar 18. An actuating cylinder 40 which cooperates with this actuating external drum 10 slides along the inner peripheral surface of an external drum circular ring 12 and the external peripheral surface of the 1st flange 20 through bushings 41, 21, respectively. It consists of an inner drum circular ring 42 freely movable to the X-X direction, the 2nd flange 44 which cooperates with the central circular pillar 18 installed at the right end part of the ring 42, and an inner drum bottom plate 46 installed at the left end part thereof. With this, three spaces 48, 50, 52 are formed and the spaces 48, 52 are communicated through a passage 58.
