Abstract

PURPOSE: To provide a cylinder device which can generate a low output by means of a fluid fed in the case of a small external power applied to a cylinder, and can generate a high output with a high pressure fluid produced at the inside in the case of a large external power.
CONSTITUTION: Each of chambers A, B, C, and E is filled with oil, and air is fed to a chamber F, whereby oil in the chamber E is pressurized through a piston 18, and a high-pressure P2, being proportioned to an area ratio b of an inner cylinder of a high-pressure side rod 2 to that of a low-pressure side cylinder 15, is generated in the chamber A. Each value is determined thereupon so that an equality of a1p1'+ f=a2bp1' is obtained, being based on a given low-pressure P1', where a1 and a2 are an effective area of low-pressure and high-pressure side piston parts of a valve body 5, and f is a slide resistance of the valve body 5. When a low-pressure p1 fed according to the above is p1>p1', the valve body 5 is moved to the right, and a large leftward force is exercised on the piston 6. In the meantime, in the case of p1<p1', the piston 6 is moved to the left with a low-output supplied to the chamber B through a path 13 and the chamber C.
