Hydraulic path repeating coil for operating hydraulic pistons has interlinked folding bellows for transmitting and for receiving with a flexible linking capillary tube to an enclosed fluid system

摘要

First folding/membrane bellows (FMB) (1) are formed by an extension spring. Second FMB (2) are formed by a compression spring. Using a hydraulic link, connections (8) and linkage hoses (3) adds traction/compression spring forces in the FMB to a common restoring force. Independent claims are also included for the following: (A) Folding/membrane metal bellows bonded to each other on the inner and outer diameters; (B) and for folding bellows for receiving; (C) and for mountings for the present invention.
