The present disclosure relates to quick connect valve, and more particularly to a quick connect valve having an integral back flow valve.
Many fluid flow systems utilize quick connect fittings in order ease the assembly and disassembly of fluid flow systems. One example of a fluid flow system that may utilize a quick connect fitting is a fluid line from a fuel tank to a fuel filter on a vehicle. A quick connect fitting allows a user to easily disconnect the fuel line from the fuel filter without the use of additional tools. One drawback of existing quick connect fittings is that a separate back flow valve, or check valve, is required within the fluid flow system to prevent fluid from flowing backwards from the intended direction when a fluid pump is not active. This may cause damage to components connected to the fluid flow system, and may allow air to enter the fluid flow system. When air enters a fluid flow system, the fluid flow system must be bled, releasing an amount of air and fluid from the system so that only fluid remains, or significant damage may result. Thus, a need exists for a quick connect fluid valve assembly having a built in back flow valve.
According to one embodiment, a quick connect fluid valve assembly comprises a housing, a flow passage insert, a moveable connector, and a biasing member. The housing has a first end an a second end. The flow passage insert is disposed within at least a portion of the housing and has a fluid flow path defined within the flow passage insert. The flow passage insert has a connected position and a disconnected position. The moveable connector is disposed in fluid communication with flow path of the flow passage insert. The moveable connector has at least one orifice. The moveable connector is movable between at least a first position relative to the flow passage insert and a second position relative to the flow passage insert. In the first position, fluid can flow within the fluid flow path of the flow passage insert and out of the at least one orifice when the flow passage insert is disposed in the connected position. In the second position, fluid is prevented from flowing within the fluid flow path of the flow passage insert and out of the at least one orifice when the flow passage insert is disposed within the connected position. The biasing member is disposed between the housing and the flow passage insert and contacts both the housing and the flow passage insert. The biasing member biases the flow passage insert towards the disconnected position. The moveable connector forms a generally fluid tight seal with the housing when the flow passage insert is disposed within the disconnected position to prevent fluid flow within the fluid flow path.
According to another embodiment, a quick connect fluid valve assembly comprises a housing, a flow passage insert, a movable connector, and a connecting collar. The flow passage insert is disposed at least partially within the housing and is movable relative to the housing between a disconnected position and a connected position. The flow passage insert has a flow path defined from a first end of the flow passage insert to a second end of the flow passage insert. The moveable connector is disposed in fluid communication with the flow path of the flow passage insert. The moveable connector has at least one orifice. The movable connector is movable between a forward fluid flow position and a backward fluid position relative to the flow passage insert. The movable connector has a ledge portion at a first end of the movable connector. The movable connector additionally is movable relative to the housing. The connecting collar is disposed between the flow passage insert and the moveable connector. The connecting collar has an extending lip at a first end of the connecting collar and is coupled to the flow passage insert at a second end of the connecting collar. The extending lip of the connecting collar contacts the ledge portion of the movable connector. The movable connector moves substantially in conjunction with the flow passage insert and relative to the housing when the flow passage insert moves from the connected position to the disconnected position.
According to a further embodiment, a quick connect fluid valve assembly comprises a housing, a flow passage insert, and a movable connector. The flow passage insert is disposed at least partially within the housing and is movable relative to the housing. The flow passage insert forms a flow path from a first end of the flow passage insert to a second end of the flow passage insert. The movable connector is disposed in fluid communication with the flow path of the flow passage insert and the movable connector has at least one orifice. The movable connector is movable between a forward fluid flow position that allows forward fluid flow within the flow path of the flow passage insert and a backward fluid flow position that prevents backward fluid flow within the flow path of the flow passage insert.

a and 1b a quick connect fluid flow valve 10 for a fluid flow system according to one embodiment. The quick connect fluid flow valve has a housing 12, a flow passage insert, or a fluid flow insert, 14, and a moveable connector 16. The housing has a first end 18, and a second end 20.
The fluid flow insert 14 is disposed within at least a portion of the housing 12. As shown in
The moveable connector 16 is disposed in fluid communication with a flow path of the flow passage insert 14. The moveable connector 16 has at least one orifice 24, although a plurality of orifices 24 are shown. The moveable connector 16 is movable between at least a first position relative to the flow passage insert 14 and a second position relative to the flow passage insert 14. In the first position of the movable connector 16 (as shown in
A connecting collar 26 connects the flow passage insert 14 to the movable connector 16. The connecting collar 26 causes the movable connector 16 to move with the flow passage insert 14 as the flow passage insert 14 moves towards the disconnected position. The connecting collar 26 interacts with a ledge portion of the movable connector 16. It is contemplated that the connecting collar 26 will only move the movable connector 16 when the flow passage insert 14 moves towards the disconnected position, and will not move the movable connector 16 when the flow passage insert 14 moves to the connected position. Rather, forward flow of fluid within the fluid passage will move the movable connector 16 to allow the fluid to flow out of the at least one orifice 24 of the movable connector 16.
The moveable connector 16 forms a generally fluid tight seal with the housing 12 when the flow passage insert 14 is disposed within the disconnected position preventing fluid flow within the fluid flow path of the flow passage insert 14 and out of the at least one orifice 24 of the movable connector 16. As shown in
