Embodiment Construction

[0021] In the following description, a method and an apparatus for piston-cylinder sealing using a helically wound seal are set forth as a preferred embodiment. It will be apparent to those skilled in the art that modifications, including additions and / or substitutions, can be made without departing from the scope and spirit of the present invention. Specific details may be omitted so as not to obscure the invention; however, the disclosure was written to enable one skilled in the art to practice the teachings herein without undue experimentation.

[0022] see figure 1 and 2 , the piston-cylinder assembly uses only one piston-block-seal type spiral wound seal 08, which is installed or closely surrounds the piston block 06 in the radial direction, instead of as many as 11 piston rings with different functions in the prior art. Installed on the piston rod seal block 04 is a single helically wound seal 12, instead of up to five piston rings of different functions in the prior a...

Abstract

A helically wound seal (08) for sealing a piston-cylinder assembly of a barrel cylinder, comprising: a piston seal C-ring (401); a connecting C-ring (402) comprising a Inner wings (501) projecting inwardly from the inner peripheral portion near the first end, and outer wings (502) projecting outward from the outer peripheral portion connecting the second end attachment of the C-ring (402); and the cylinder seal C-ring (403). Wherein, the piston seal C-ring (401) is connected end-to-end to the first end of the connecting C-ring (402), and the cylinder sealing C-ring (403) is connected end-to-end to the second end of the connecting C-ring (402). end, thus forming a three-ring helical structure with the desired short enough contraction-expansion response time for the up and down stroke speeds of the cylinder piston-cylinder assembly.
