Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 235 words
A connector for interconnecting at least one hose with a fluid operating device, comprising: a housing having a plurality of ports formed therein such that each of said at least one hose interconnects therewith; said housing having a plurality of openings formed therein communicating with said plurality of ports, respectively; a bushing mounted within each of said plurality of openings for fluid communication with said fluid operating device; a sealing flange extending from said housing of said connector such that said sealing flange prevents each of said bushings from being axially removed from said housing; a plurality of annular sealing means formed on the outer periphery of each said bushing for airtight engagement with said housing wherein said plurality of annular sealing means formed on the outer periphery of each said bushing further comprises a plurality of first sealing means triangular in cross section such that each said bushing provides an equal sealing capacity in both an upstream and downstream direction; and a plurality of annular sealing means formed on the inner periphery of each said bushing wherein said plurality of annular sealing means formed on the inner periphery of each said bushing further comprises a plurality of second sealing means triangular in cross section such that each said bushing provides an equal sealing capacity in both an upstream and downstream direction wherein equidistant air gaps are formed between said first and second sealing means.
Claim 2
Dependent Claim 235 words
A connector for interconnecting at least one hose with a fluid operating device, comprising: a housing having a plurality of ports formed therein such that each of said at least one hose interconnects therewith; said housing having a plurality of openings formed therein communicating with said plurality of ports, respectively; a bushing mounted within each of said plurality of openings for fluid communication with said fluid operating device; a sealing flange extending from said housing of said connector such that said sealing flange prevents each of said bushings from being axially removed from said housing; a plurality of annular sealing means formed on the outer periphery of each said bushing for airtight engagement with said housing wherein said plurality of annular sealing means formed on the outer periphery of each said bushing further comprises a plurality of first sealing means triangular in cross section such that each said bushing provides an equal sealing capacity in both an upstream and downstream direction; and a plurality of annular sealing means formed on the inner periphery of each said bushing wherein said plurality of annular sealing means formed on the inner periphery of each said bushing further comprises a plurality of second sealing means triangular in cross section such that each said bushing provides an equal sealing capacity in both an upstream and downstream direction wherein equidistant air gaps are formed between said first and second sealing means.
Claim 3
Dependent Claim 34 words
A connector as set forth in claim 1, wherein said plurality of first sealing means further comprises at least three seals and said plurality of second sealing means further comprises at least two seals.
Claim 4
Dependent Claim 17 words
A connector as set forth in claims 1, or 2 wherein said bushing comprises an elastic bushing.
