Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
94 words
A two piece flow restricting hose assembly comprising: (a) a one piece flexible tubular conduit having a length considerably greater than its diameter and having two ends and having a permanently expanded cylindrical portion therein proximate to one end thereof and (b) a cylindrical insert having a longitudinal aperture along its axis and having an outside diameter and being coaxially disposed entirely within said expanded portion of said tubular conduit, wherein said expanded portion has an inner diameter which is slightly smaller than said outside diameter to provide a tight fit about said insert.
Claim 2
Dependent Claim
94 words
