Abstract
A vibration absorbing, noise attenuating connector utilizing threadless coupling connecting means including a quick disconnect feature for use in hydraulic, pneumatic and refrigeration conduit systems.
Claims16
A connector comprising:
- (a) a tubular member having a wall extending along an axis to an open end, said wall having a cylindrical outer surface portion and engagement means;
- and,
- (b) a coupling member having
- (i) a casing with an annular side wall and spaced apart first and second ends, each of said ends having an opening lying along an axis;
- (ii) a vibration absorbing member within said casing, said vibration absorbing member including a supported end adjacent said casing first end, a free end, an external wall portion between said supported end and said free end, and an inner wall defining an axial passageway generally aligned with said axis;
- (iii) means extending from said casing first end for supporting said vibration absorbing member within said casing with said external wall portion and said free end in spaced relationship with said casing second end and annular side wall and cooperating with said casing to define a gap, said means permitting angular displacement of said vibration absorbing member within said gap;
- and
- (iv) retention means on said vibration absorbing member for rapidly engaging and disengaging said tubular member within said central passageway in sealing relationship.

A connector comprising:
- (a) a tubular member having a wall extending along an axis to an open end, said wall having a cylindrical outer surface portion and engagement means;
- and,
- (b) a coupling member having
- (i) a casing with an annular side wall and spaced apart first and second ends, each of said ends having an opening lying along an axis;
- (ii) a vibration absorbing member within said casing extending from a supported end adjacent said casing first end to a free end spaced from said casing second end, said vibration absorbing member having an inner wall defining an axial passageway generally aligned with said axis and an annular outer wall;
- (iii) means extending from said casing first end for supporting said vibration absorbing member within said casing in spaced relationship with said casing second end and annular side wall, said means permitting angular displacement of said vibration absorbing member adjacent said free end;
- and
- (iv) retention means on said vibration absorbing member for retaining said tubular member within said central passageway in sealing relationship, said retention means including
- (A) an annular body member positioned within said axial passageway and sized to receive said tubular member, said body member being mounted on said vibration absorbing member adjacent said free end;
- (B) annular gasket means retained with said body member for receiving said tubular member in sealing relationship with said outer surface portion;
- and
- (C) latch means cooperating with said body member for receiving said tubular member and engaging said engagement means;
- said body member including a first cylindrical wall portion having a predetermined diameter encircling said latch means and terminating at an inwardly directed shoulder, a second cylindrical wall portion having a diameter smaller than said predetermined diameter extending from said shoulder and encircling said annular gasket means, a second shoulder extending inwardly from said second cylindrical wall portion, said gasket means being retained between said latch means and said second shoulder.
