Title:
CYLINDERS
Document Type and Number:
Japanese Patent JPS5514309
Kind Code:
A
Abstract:
PURPOSE:To permit cylinders to produce high output by using the area difference in the pressurized sections on both sides of a piston, removing the one-sided fluid, and applying high pressure to the piston. CONSTITUTION:Cylinder rooms B and D and the passage 4 are filled with pressure medium fluid. When the intra-D room pressure exceeds the preset value, the spring 13 is set so that the valve piece 15 can move. When air is supplied to rooms A and C, the fluid in room B flows into room D and drives the piston 2. When the pressure in room D exceeds the preset value and when the air in room C is removed, the high pressure which is proportional to the area ratio of both the piston 5 and the rod 3 is generated in room D, thereby enabing the rod 16 to obtain high power and the cylinder to produce high output.
