Transmission cylinder without axial limitation

Abstract

A transmission cylinder without axial limitation. A piston is disposed in the transmission cylinder. Multiple flexible members are disposed on one side of the piston. A resilient member is fitted around the flexible members. Each flexible member extends within a guide member which is fixed at a portion of a certain structure. The piston is driven by a power source, whereby the flexible members are flexibly moved along and within the guide member to transmit power in multiple axial directions.

What is claimed is:  
     
         1 . A transmission cylinder without axial limitation, the transmission cylinder being a close cylinder in which a piston is disposed to divide the transmission cylinder into a first space and a second space, two sides of the transmission cylinder being respectively formed with an inlet and a through hole communicating with the interior of the transmission cylinder, at least one flexible member being connected with one side of the piston and extended out of the transmission cylinder through the through hole.  
     
     
         2 . The transmission cylinder without axial limitation as claimed in  claim 1 , wherein the inlet is formed on one side of the first space, while the flexible member is disposed on one side of the piston distal from the inlet.  
     
     
         3 . The transmission cylinder without axial limitation as claimed in  claim 1 , wherein a resilient member which is a compression spring is fitted around the flexible member, two ends of the resilient member respectively abutting against one side of the piston and the wall of the transmission cylinder, an inner diameter of the resilient member being slightly larger than the total diameter of the flexible member.  
     
     
         4 . The transmission cylinder without axial limitation as claimed in  claim 1 , wherein the flexible member is a steel cord.  
     
     
         5 . The transmission cylinder without axial limitation as claimed in  claim 1 , wherein the flexible member extends within a guide member.  
     
     
         6 . The transmission cylinder without axial limitation as claimed in  claim 1 , wherein the transmission cylinder is a bi-directional operable cylinder and the second space thereof is formed with a second through hole.  
     
     
         7 . The transmission cylinder without axial limitation as claimed in  claim 1 , wherein the transmission cylinder using gas which is ignited and explodes, an igniter being disposed near the inlet, a resilient member being fitted around the flexible member, two ends of the resilient member respectively abutting against one side of the piston and the wall of the transmission cylinder.
