TW377389B - High-load hydraulic (pneumatic) cylinder structure - Google Patents

Abstract

The present invention relates to a high-load fluid (gas) cylinder structure having the body of the fluid (gas) cylinder structure an action rod with the receiving end disposed at a proper section of the action rod driven by the reciprocal flow of the fluid (gas) in the cylinder, making the action rod make telescopic movement for the creation of driving force, having on both sides of the receiving end more than 1 bearing, and a leakage-proof ring disposed between the bearing and the receiving end, creating a gap between the bearing and the receiving end by means of the leakage-proof ring, having the bearing on the action rod a ring latch for positioning and at least one bearing at the exit of the cylinder body, plus a leakage-proof ring between the bearing and the outlet cap, so that the fluid (gas) inside the cylinder would drive the action rod in telescopic movement, creating pushing pressure onto the bearing, which would have the pressure be reacted onto the leakage-proof ring, so that the leakage-proof ring would, when pressed by the receiving end and the bearing, respond to the inner wall of the cylinder by pushing it, thus increasing the high-load of the action rod toward outside.
