Abstract
A fluid line quick connector for joining fluid lines together, such as coolant fluid lines in electric vehicle automobile applications, among other possible applications. A check valve is incorporated into the fluid line quick connector in order to preclude unwanted backflow through a passage of the fluid line quick connector. The check valve has a rigid partition wall and a flexible diaphragm. The partition wall has one or more through-holes residing therein. The diaphragm closes the through-hole(s), and moves relative to the partition wall in order to open a portion or more of the through-hole(s).
Claims19
A fluid line quick connector, comprising:
- a housing having a passage;
- a partition wall extending across said passage, at least one through-hole residing in said partition wall;
- and
- a diaphragm situated on a downstream side of said partition wall, said at least one through-hole closed by said diaphragm, and said at least one through-hole openable by fluid-flow travel through said at least one through-hole and urging of movement of said diaphragm downstream of said partition wall by the fluid-flow travel.
A fluid line quick connector, comprising:
- a housing having a passage;
- a partition wall situated in said passage, said partition wall having at least one through-hole residing therein;
- a diaphragm situated on a downstream side of said partition wall;
- and
- an extension spanning from one of said partition wall or said diaphragm, and an opening residing in the other of said partition wall or said diaphragm, receipt of said extension in said opening movably anchoring said diaphragm to said partition wall;
- wherein surface-to-surface abutment between said partition wall and said diaphragm closes said at least one through-hole, and axial separation between said partition wall and said diaphragm via said extension opens said at least one through-hole.
A fluid line quick connector, comprising:
- a housing having a passage;
- a partition wall extending across said passage, at least one through-hole residing in said partition wall, said partition wall being a rigid structure;
- a diaphragm situated on a downstream side of said partition wall, said diaphragm being a flexible structure;
- and
- an extension spanning from one of said partition wall or said diaphragm, and an opening residing in the other of said partition wall or said diaphragm, receipt of said extension in said opening movably anchoring said diaphragm to said partition wall, said extension having a stalk portion and a flanged end portion;
- wherein, when said at least one through-hole is closed, a first clearance is established between confronting surfaces of said flanged end portion and said partition wall or said diaphragm, and wherein, when said at least one through-hole is open, a second clearance is established between confronting surfaces of said partition wall and said diaphragm, and a third clearance is established between said diaphragm and an inside surface of said passage.
