Reinforced hose and retainer ring assembly

A self-adjusting clamping assembly for joining and retaining an end portion of a flexible hose and the end portion of a component in predetermined overlapping positions relative to one another wherein one of the end portions includes a beaded-end portion, comprising:

• a substantially ring-shaped clamping member having one end portion of partially curved configuration and an opposite end portion of substantially cylindrical configuration;
• the substantially cylindrical end portion of the clamping member being adaptable for overlapping an outer surface of the overlapping end portion;
• the curved-end portion of the clamping member being of partially spherical configuration and adaptable for covering about one-half (1/2) of the beaded-end portion when pressing the overlapping end portions together;
• whereby the partially spherically-shaped end portion presses one overlapping end portion into the beaded end with a pressure that increases as the pressure of the gas or fluid flowing through the inner liner increases.

A method of forming an improved flexible hose assembly capable of transmitting pressurized gases and/or fluids between a pair of components, comprising the steps of:

• extruding a length of thermoplastic material to form a flexible helix having a outer surface portion with an irregular cross-section and an inner surface portion of substantially cylindrical cross-section;
• positioning the helix to enclose a flexible inner liner of substantially cylindrical configuration so that the inner surface portion of the helix contacts substantially the entire outer surface of the inner liner;
• and;
• bonding the contracting surfaces of the inner liner and helix to one another.
