Abstract
An expandable hose having an outer layer and an inner duct is disclosed. The inner duct creates a fluid flow path between a first end and the second end of the expandable hose through each of a first connector and the second connector. The inner duct is constructed of a corrugated, flexible material to allow for expansion in response to increased fluid pressure in the expandable hose, which causes a lengthening of the expandable hose. The outer layer is not directly connected to the inner duct. The outer layer is made of a flexible material to allow for responsive expansion and contraction. Upon a decrease in fluid pressure, the outer layer contracts, which in turn causes the inner duct to contract in response.
Claims19
An expandable hose, comprising:
- an inner duct comprising a corrugated, flexible material that comprises a series of continuous and alternating peaks and valleys when in a contracted state and is configured to expand and contract in an accordion-like manner;
- an outer layer comprising an elastic fabric material;
- a first end having a first connector and a first termination point for the inner duct and the outer layer;
- and
- a second end having a second connector and a second termination point for the inner duct and the outer layer;
- wherein the inner duct provides a fluid flow path between the first end and the second end through each of the first connector and the second connector and the corrugated, flexible material of the inner duct is configured to allow for expansion of the inner duct in response to an increase in fluid pressure in the inner duct;
- and
- wherein the outer layer is configured to elongate in response to the expansion of the inner duct and the outer layer is further configured to contract upon a decrease in fluid pressure, causing the inner duct to contract in response.

An expandable hose, comprising:
- an inner duct comprising a corrugated, flexible material comprising a series of continuous and alternating peaks and valleys in a contracted state and is configured to expand and contract in an accordion-like manner;
- an outer layer comprising an elastic fabric material;
- a sheath, surrounding the inner duct and located between the inner duct and the outer layer;
- a first end having a first connector and a first termination point for the inner duct, the sheath, and the outer layer;
- a second end having a second connector and a second termination point for the inner duct, the sheath, and the outer layer;
- and
- wherein the sheath is continuous between the first and second termination points and is connected to the inner duct between the first and second termination points and is not connected to the outer layer between the first and second termination points;
- wherein the inner duct provides a fluid flow path between the first end and the second end through each of the first connector and the second connector and the corrugated, flexible material of the inner duct is configured to allow for expansion of the inner duct in response to an increase in fluid pressure in the inner duct;
- and
- wherein the outer layer is configured to elongate in response to the expansion of the inner duct and the outer layer is further configured to contract upon a decrease in fluid pressure, causing the inner duct to contract in response, and wherein further the sheath is configured to assist with the contraction of the inner duct.
