Abstract
An end cap assembly for a fluid cylinder includes a cylindrical casing having a longitudinal axis and an open end, and an end cap closing the open end of the casing. The end cap has a first connecting device for connecting with the casing, and the casing has a second connecting device for connecting with the end cap, whereby the first and second connecting devices interconnect with each other. A backup device is disposed separate from and engaged against the casing or end cap, and prevents deflection of the engaged casing or end cap in a direction transverse to the longitudinal axis.
Claims4
An end cap assembly for a fluid cylinder, comprising:
- a cylinder casing having a longitudinal axis and an open end;
- an end cap closing said open end of said casing;
- said end cap having a first connecting means for connecting with said casing, and said casing having a second connecting means for connecting with said end cap, said first and said second connecting means interconnecting with each other;
- and
- a backup ring disposed radially outside of and engaged against said casing without plastically deforming said casing, said backup ring preventing deflection of said engaged casing in a direction radially outward from said longitudinal axis.
An end cap assembly for a tube adapted to contain a fluid, comprising:
- an elongate, hollow casing having an open end and an annular groove;
- an end cap closing said open end of said casing and having an annular groove;
- and
- a one-piece retainer ring disposed in each of said casing annular groove and said end cap annular groove, said retainer ring having a generally V-shaped cross-section pointing in a direction parallel to the longitudinal axis;
- at least one of said casing and said end cap consisting essentially of a composite material.
