Abstract

A branched hose connector includes a branched inner pipe substantially made from a suitable lightweight material, a plurality of hoses connected onto the branched inner pipe, a cover covering the branched inner pipe and a portion of the hoses to join the branched inner pipe and the hoses, and an integrally formed flange projecting outwardly. The branched hose connector is lightweight so that it can be installed with ease via the flange, and it can be manufactured easily and less expensively. Further, the branched hose connector can include a valve member, and a convexity and a concavity provided on opposing end surfaces of the branched inner pipe and the valve member. With these extra features, the valve member can be tightened into the branched inner pipe with a predetermined appropriate torque by a manual operation alone, and it can resist loosening by vibrations, or the like.

Claims

1. A branched hose connector comprising:

a plurality of hoses;

a branched pipe assembly which includes a primary pipe and a plurality of secondary pipes extending from and in fluid communication with said primary pipe, said plurality of hoses each having respective ends connected onto respective said secondary pipes;

a cover independent of said branched pipe assembly and shrink-fit over at least a portion of said branched pipe assembly and said respective ends of said plurality of hoses, wherein the ends of said respective hoses are held between said cover and said respective secondary pipes; and

a flange projecting outwardly from said cover and said branched pipe assembly, for mounting said branched hose connector.

2. A branched hose connector according to claim 1, wherein said cover is made from a material which has an elastic modulus of at least about 5000 kgf/cm².

3. A branched hose connector according to claim 1, wherein the materials constituting the cover and the flange are selected from a group consisting of polyamide resins, polypropylene resins, and polyacetal resins.

4. A branched hose connector as in claim 1, wherein the materials constituting said cover and said flange contain glass fiber.

5. A branched hose connector according to claim 1, wherein said branched pipe assembly is made from a nylon containing glass fibers.

6. A branched hose connector according to claim 1, wherein said branched pipe assembly and said cover are made from the same material.

7. A branched hose connector according to claim 1, further comprising at least one structural reinforcing member extending from said flange to a portion of said cover covering said primary pipe.

8. A branched hose connector according to claim 1, wherein said flange is integrally formed with said cover.

9. A branched hose connector according to claim 1, wherein said flange is integrally formed with said branched pipe assembly.
