초록 ▼

A reusable hose fitting, which may be assembled using simple hand tools, includes a fitting body having an exteriorly threaded section on which is received a threaded bore of a compression nut. The fitting body includes a nipple having a diameter somewhat less than the threaded section and joined thereto by an annular locating surface. A compressible sleeve is located within the compression nut and has a pair of axially spaced, frusto-conical exterior surfaces which cooperate with complementary interior surfaces of the compression nut to exert a pair of axially spaced zones of pressure to clamp a hose, that has its end positioned against the locating surface of the fitting body, against the nipple. Cooperating surfaces of the compression nut and compressible sleeve prevent the latter from being accidentally dislodged from the compression nut once inserted past the threaded bore of the nut. A pair of o-rings having different outside diameters are provided in axially spaced grooves in the nipple so that effective sealing may be accomplished with hoses having slightly different inside diameters.

대표청구항 ▼

In a hose fitting including a fitting body, a compressible collet and a compression nut, with said fitting body having an exteriorly threaded section to which is joined a nipple having an outside diameter somewhat less than a diameter of said threaded section so as to define an annular stop surface facing axially in a first direction, with said compression nut being disposed in concentric relationship to said nipple and having a threaded bore at one end screwed onto said threaded section of said fitting body and with said collet being received within said compression nut and having a frusto-conical exterior surface section located for cooperating with a frusto-conical interior surface section of said compression nut to effect a first force in a first zone for deflecting the collet inwardly as the compression nut moves axially in a second direction relative to said collet when being screwed onto said threaded section, the improvement comprising: said collet having a second frusto-conical exterior surface section spaced axially from said first-named frusto-conical exterior surface; section and said compression nut having a second frusto-conical interior surface section spaced axially from said first-named frusto-conical exterior surface section, with said second exterior and interior frusto-conical surface sections being disposed for cooperating with each other to effect a second force in a second zone for deflecting the collet inwardly as the compression nut moves axially in said second direction relative to said collet; and said collet having an annular surface joined to said second frusto-conical surface and facing axially in said second direction; and said compression nut including an annular retaining surface located radially outwardly of said threaded bore and disposed in confronting relationship to said shoulder, whereby said collet may be preassembled by inserting it through said threaded bore of said compression nut while the collet is in an inwardly compressed state, the collet then returning to its uncompressed state where the annular shoulder thereof confronts the retaining surface of said compression nut and thus is prevented from being dislodged from the interior of said compression nut.
