Abstract
Abstract A conduit is provided for use in fluid-conducting systems which are subjected to pressure surges and includes an inner conduit for carrying fluid which is surrounded by a body of resilient material adapted to absorb undulations of the inner conduit in response to pressure surges of the fluid. In one embodiment the inner conduit is an expandable conduit and the resilient body is contained within a reinforcing member. In this embodiment, the inner conduit expands in response to pressure surges and thereby functions as an accumulator, so as to prevent damage to equipment in the system, such as pressure gauges, piping, and conduits, or for example, to even out the flow discharge from a positive displacement pump for the fluid.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
72 words
A flexible hose for carrying a fluid which is subjected to pressure surges comprising: a. an inner flexible non-expandable, high strength pressure conduit capable of carrying fluid under pressure; b. an annular resilient cushion body positioned around said inner flexible pressure conduit for absorbing undulations of said inner flexible pressure conduit in response to said pressure surges; and c. an outer flexible abrasion resistant tubular body encompassing said annular resilient cushion member.
Claim 2
Dependent Claim
72 words
A flexible hose for carrying a fluid which is subjected to pressure surges comprising: a. an inner flexible non-expandable, high strength pressure conduit capable of carrying fluid under pressure; b. an annular resilient cushion body positioned around said inner flexible pressure conduit for absorbing undulations of said inner flexible pressure conduit in response to said pressure surges; and c. an outer flexible abrasion resistant tubular body encompassing said annular resilient cushion member.
Claim 3
Dependent Claim
18 words
The conduit of claim 1 wherein said annular resilient cushion member is made of closed cell foam rubber.
Claim 4
Dependent Claim
27 words
The flexible hose of claim 1 further comprising end fittings operatively connected to each end of said flexible hose for attachment to fluid delivery and receiving means.
Claim 5
Dependent Claim
133 words
A flexible hose assembly for carrying the fluid which is subjected to pressure surges comprising: a. an inner flexible non-expandable, high strength pressure conduit capable of carrying fluid under pressure; b. an annular resilient cushion body made of a closed cell foam rubber positioned around all except the end portions of said inner flexible pressure conduit for absorbing undulations of said inner flexible conduit in response to said pressure surges; c. an outer flexible abrasion resistant tubular body encompassing said annular resilient cushion body and the end portions of said inner flexible pressure conduit not encompassed by said annular resilient cushion body; and d. end fittings for connection with fluid delivery and receiving means operatively attached to the end portions of said inner flexible pressure conduit and said outer flexible abrasion-resistant tubular body.
Claim 6
Dependent Claim
133 words
A flexible hose assembly for carrying the fluid which is subjected to pressure surges comprising: a. an inner flexible non-expandable, high strength pressure conduit capable of carrying fluid under pressure; b. an annular resilient cushion body made of a closed cell foam rubber positioned around all except the end portions of said inner flexible pressure conduit for absorbing undulations of said inner flexible conduit in response to said pressure surges; c. an outer flexible abrasion resistant tubular body encompassing said annular resilient cushion body and the end portions of said inner flexible pressure conduit not encompassed by said annular resilient cushion body; and d. end fittings for connection with fluid delivery and receiving means operatively attached to the end portions of said inner flexible pressure conduit and said outer flexible abrasion-resistant tubular body.
