Abstract
Abstract Coaxial elastomer hoses are hydraulically coupled to fluid units by male plug-in connector assemblies, each incorporating concentric pipes which are pre-assembled on the hoses. Each pipe extends axially from the associated hose and carries a sleevelike fitting and a fluid sealing O-ring disposed adjacent to the ends thereof. A single snap ring retains the plug-in connector assembly in installed position in the fluid unit and securely anchors each of the concentric pipes to the fluid unit housing.

Claim 1
Independent Claim
215 words
A fluid transmitting system for a fluid unit comprising a fluid unit inner and outer flexible hose means providing separate fluid flow passages, connector assembly means coupling said hose means to said fluid unit, said connector assembly means comprising first pipe means operatively connected to said inner hose means and extending from one end thereof, said first pipe means having first outwardly extending rib means, first and second retainer means disposed on opposite sides of said first rib means, first annular fluid seal means disposed around said first pipe means disposed adjacent to one end of said first retainer means to trap said first retainer means against said first rib means, second pipe means disposed around said inner pipe means operatively connected to said outer hose means and extending from one end thereof, said second pipe means having outwardly extending second rib means, third and fourth retainer means disposed on opposite sides of said second rib means, second annular fluid seal means disposed around said second pipe means to trap said third retainer means against said second rib means, and fastener means secured to said fluid unit abutting said fourth retainer means and holding said outer pipe means in abutting relationship wih said second retainer means thereby holding said connector assembly in said fluid unit.

A fluid transmitting system for a fluid unit comprising a fluid unit inner and outer flexible hose means providing separate fluid flow passages, connector assembly means coupling said hose means to said fluid unit, said connector assembly means comprising first pipe means operatively connected to said inner hose means and extending from one end thereof, said first pipe means having first outwardly extending rib means, first and second retainer means disposed on opposite sides of said first rib means, first annular fluid seal means disposed around said first pipe means disposed adjacent to one end of said first retainer means to trap said first retainer means against said first rib means, second pipe means disposed around said inner pipe means operatively connected to said outer hose means and extending from one end thereof, said second pipe means having outwardly extending second rib means, third and fourth retainer means disposed on opposite sides of said second rib means, second annular fluid seal means disposed around said second pipe means to trap said third retainer means against said second rib means, and fastener means secured to said fluid unit abutting said fourth retainer means and holding said outer pipe means in abutting relationship wih said second retainer means thereby holding said connector assembly in said fluid unit.
Claim 3
Dependent Claim
245 words
In a fluid transmitting system for fluid unit means, said system having fluid unit means inner and outer flexible hose means providing separate fluid flow passages and connector assembly means for said hose means, said connector assembly means comprising first pipe means operatively connected to said inner hose means and extending from one end thereof, said first pipe means having annular rib means extending radially outwardly therefrom, first and second retainer means disposed on opposite sides of said rib means, first annular fluid seal means disposed around said first pipe means disposed adjacent to an end of said first retainer means to trap said first retainer means against said rib means, second pipe means operatively connected to said outer hose means and extending from one end thereof around said first pipe means, said second pipe means having an end terminating adjacent to said first rib means, said second pipe means having second rib means extending radially outwardly therefrom, third and fourth retainer means disposed on opposite sides of said second rib means, second annular fluid seal means disposed around said second pipe means to trap said third retainer means against said second rib means, and unitary fastener means secured to said fluid unit means abutting said fourth retainer means thereby securing said outer pipe means to said fluid unit means and holding said outer pipe means in abutting relationship with said second retainer means to thereby secure said inner pipe to said fluid unit means.
Claim 4
Dependent Claim
245 words
In a fluid transmitting system for fluid unit means, said system having fluid unit means inner and outer flexible hose means providing separate fluid flow passages and connector assembly means for said hose means, said connector assembly means comprising first pipe means operatively connected to said inner hose means and extending from one end thereof, said first pipe means having annular rib means extending radially outwardly therefrom, first and second retainer means disposed on opposite sides of said rib means, first annular fluid seal means disposed around said first pipe means disposed adjacent to an end of said first retainer means to trap said first retainer means against said rib means, second pipe means operatively connected to said outer hose means and extending from one end thereof around said first pipe means, said second pipe means having an end terminating adjacent to said first rib means, said second pipe means having second rib means extending radially outwardly therefrom, third and fourth retainer means disposed on opposite sides of said second rib means, second annular fluid seal means disposed around said second pipe means to trap said third retainer means against said second rib means, and unitary fastener means secured to said fluid unit means abutting said fourth retainer means thereby securing said outer pipe means to said fluid unit means and holding said outer pipe means in abutting relationship with said second retainer means to thereby secure said inner pipe to said fluid unit means.
Claim 5
Dependent Claim
246 words
In a system for transmitting fluid to and from a fluid unit, inner and outer flexible hose means providing separate fluid flow passages, a fluid unit, connector assembly means for said hose means providing a plug-in connection with said fluid unit, said connector assembly means comprising first pipe means operatively connected to said inner hose means and extending from one end thereof to a first terminal point, said first pipe means having first annular rib means extending outwardly therefrom, first and second retainer means disposed on opposite sides of said first rib means, first annular fluid seal means disposed around said first pipe means disposed adjacent to an end of said first retainer means to trap said first retainer means against said First rib means, second pipe means disposed around said first pipe means operatively connected to said outer hose means and extending from one end thereof to a second terminal point short of said first terminal point, said second pipe means having second projecting rib means extending radially outwardly therefrom, third and fourth retainer means disposed on opposite sides of said second rib means, second annular fluid seal means disposed around said second pipe means to trap said third retainer means against said second rib means, and snap ring means secured to said fluid unit abutting said fourth retainer means and holding said outer pipe means in abutting relationship with said second retainer means to thereby secure said connector assembly means in said fluid unit.
