Abstract
PURPOSE: To improve sealability by maintaining the pressure between the piston and the cylinder at a constant value regardless of temperature change in a mechanism wherein a sleeve and a piston ring are installed at the tip of the piston and the sleeve is kept pressured against the inside wall of the cylinder by gas.
CONSTITUTION: A top-plate 3 is attached at the top of the piston 2, and a piston ring 5 is inserted into a groove being formed in the vicinity of the top-plate 3. A sleeve 6 made of synthetic resin without cut section is attached on the surface of the piston 2 and the piston ring 5, and its one end A is bulged inwardly to maintain sealability between the piston 2 and the cylinder. A clearance is provided between the inside of the sleeve 6 and the top-plate 3 of the piston 2, wherein the gas pressure leaking out from the piston ring 5 is actuated on the sleeve 6, which pressures the sleeve 6 against the inner wall of the cylinder 1. By this structure, sealability between the sleeve 6 and the cylinder 1 is maintained excellently even under low temperature.
