Abstract
A connector for connecting a pipe, such as a fuel pipe, to another fuel pipe or pipe terminal, having a first connector element including a first female sub-element and a concentric second female sub-element, a first seal seat positioned within the first female sub-element, a second seal seat positioned in the concentric second female sub-element, a first seal retained within the first seal seat, a second seal retained the second seal seat, and a second connector element providing a connection for a pipe at one end and connection to the first connector element at a second end.
Claims9
A pipe connector, comprising:
- a first connector element comprising a generally cylindrical body member having a central axis and providing a connection for a pipe at one end, said first connector element having a first female sub-element including a first opening and a second opening defining a first passageway therebetween, and a concentric second female sub-element including a third opening and a fourth opening defining a second passageway therebetween;
- a terminal connector attached to said first female sub-element for connecting said first connector element to a terminal, wherein said terminal connector includes a first port and a concentric second port;
- a first seal seat recessed within an inner surface of said first female sub-element;
- a second seal seat recessed within an inner surface of said concentric second female sub-element;
- a first seal retained within said first seal seat;
- a second seal retained within said second seal seat;
- a second connector element comprising a generally cylindrical body member having a central axis and providing a connection for a pipe at one end and connection to said first connector element at a second end,
- said second connector element having first male sub-element and a concentric second male sub-element each having a bearing surface being radially disposed and configured such that said second connector concentric male sub-element bearing surface maintains sealing engagement with said second seal within a predetermined range of relative movement of the first and second connector elements, and said second connector first male sub-element bearing surface maintains sealing engagement with said first seal within said predetermined range of relative movement, wherein said predetermined range of relative movement comprises relative movement longitudinally along said central axis, wherein said predetermined range of relative movement also comprises relative rotation about said central axis and in planes parallel with said central axis, and wherein a first fluid flow path exists within said first female sub-element through said first passageway, and a second separate fluid flow path exists within said concentric second female sub-element through said second passageway.
