Connector for hoses and the like

A connector for hoses and the like having, in combination, a first tubular member having an inlet end portion and a first sealing end portion, a second tubular member having an outlet end portion and a second sealing end portion telescoping with said first sealing end portion, one of said members having a cylindrical skirt encircling and projecting axially beyond the sealing end portion of that member and the other of said members having a cylindrical sleeve encircling and extending beyond the sealing end portion of that member, said sleeve telescoping with said skirt, said members having alined axial passages for the flow of pressure fluid from said inlet end portion to said outlet end portion, an axially facing annular sealing surface formed on the sealing end portion of said second member and encircling the passage in that member, said surface facing said inlet end portion of said first member, a cylindrical sealing element of resilient material carried by the sealing end portion of said first member and encircling the passage in that member, an annular lip formed on said element and opposing said sealing surface around the entire circumference thereof, said lip being inclined radially inwardly and axially toward said sealing surface to engage and to flex and at least partially flatten against the surface around the entire circumference thereof when said sleeve and said skirt are telescoped, said pressure fluid urging said lip against said sealing surface, and means for releasably connecting said members with said sleeve and said skirt telescoped, said means including a first set of parts formed on and angularly spaced around an exterior portion of one of said members and a second set of parts formed and angularly spaced around an interior portion of the other of said members, said parts being positioned so that one set of parts passes between the other set of parts as said sleeve and said skirt are telescoped and thereafter said two sets of parts being generally axially alined when one of said members is turned relative to the other, said lip urging said sets of parts into engagement when the latter are axially alined.

A connector for hoses and the like having, in combination, a first elongated tubular member made of rigid material and having an outer inlet end portion and an inner end portion, said member defining a first axial passage extending from said inlet end portion into said inner end portion, said inner end portion including an axial flange surrounding said passage and stopping short of the inner end of said member and an integral cylindrical skirt spaced radially outwardly from said flange and projecting beyond the end of the flange, a generally cylindrical seal made of a resilient material and disposed within said first member with its outer surface bearing against the inside of said skirt, said seal having a first portion projecting into the space between said skirt and said flange and a second portion extending beyond the end of the flange but stopping short of the end of its skirt whereby said second portion forms a continuation of said passage, said seal including an integral lip projecting radially inwardly from the free end of said second portion and being inclined away from said inlet end of said member, a second elongated tubular member made of a rigid material and having an outer outlet end portion and a cylindrical inner end portion, said cylindrical inner end portion being smaller in diameter than said skirt to project into the latter, an axially facing annular sealing surface formed on the end of said cylindrical end portion to engage and flatten said lip as the cylindrical end portion is projected into said skirt, said second member defining a second passage alined with said first passage, an annular flange formed on the exterior of said second member intermediate the ends thereof, a cylindrical sleeve rigid with the periphery of said annular flange and extending away from said outlet end portion and beyond said sealing surface to telescope said skirt on the outer side thereof when said cylindrical inner end portion is projected into the skirt, the inner surface of said sleeve being spaced from and opposing the outer surface of said skirt, and means including coacting parts formed on the opposing surfaces of said sleeve and said skirt, said parts being operable to permit said axial inner end portion to be projected into said skirt and thereafter move into locking engagement when one of said members is turned relative to the other of said members thereby to lock said members together, said lip engaging said sealing surface and being progressively flattened thereby as said cylindrical inner end portion is projected into said skirt and said lip resiliently hold said parts in locking engagement after said members have been turned relative to each other.
