Priming pump with reed valve
View Patent ↗A fluid priming pump in combination with a reed valve for the control of incoming and exiting fluid flow is disclosed. The fluid priming pump includes a pump body and a movable plunger with the reed valve positioned adjacent the pump body. Two embodiments of the reed valve are disclosed, including an integral design where the unitary valve panel is insert molded with the valve body. In the second embodiment, the unitary reed valve is based on co-injection molding technology. Each reed valve design comprises only two component parts and becomes operable without the need for any additional mechanical components or fasteners. Pressure forces created by the fluid priming pump govern the opening and closing of valve panel portions for controlling the incoming and exiting fluid flow through the fluid priming pump.
1. An integral reed valve for controlling the incoming and exiting fluid flow through a fluid priming pump, said integral reed valve comprising:
a solid molded valve body defining an inlet opening, a control valve opening and an outlet opening; and
a unitary valve panel having a first portion molded within said solid molded valve body, a second portion cantilevered over said inlet opening and a third portion cantilevered over said outlet opening, wherein said second and third portions are constructed and arranged to flex in response to pressure forces to alternately open and close said inlet and outlet openings.
2. The integral reed valve of claim 1 wherein said solid molded valve body defines a plunger-side surface and an oppositely-disposed second surface and said first portion extends through said solid molded valve body from said plunger-side surface to said second surface.
3. The integral reed valve of claim 2 wherein said second portion is positioned against said plunger-side surface.
4. The integral reed valve of claim 3 wherein said third portion is positioned against said second surface.
5. The integral reed valve of claim 4 wherein said inlet opening includes an inset shelf for receiving and seating the second portion.
6. The integral reed valve of claim 1 wherein said unitary valve panel is comprised of a plastic or composite material.
7. In combination:
a fluid priming pump including a pump body and a moveable plunger positioned within said pump body; and
an integral reed valve positioned adjacent said pump body for controlling the incoming and exiting fluid flow through a fluid priming pump, said integral reed valve comprising:
a seamless solid molded valve body defining an inlet opening and an outlet opening; and
a unitary valve panel having a first fixed portion molded within said seamless solid molded valve body, a second portion cantilevered over said inlet opening and a third portion cantilevered over said outlet opening, the seamless solid molded valve body enveloping the first fixed portion of the unitary valve panel such that the first fixed portion of the unitary valve panel is surrounded by the seamless solid molded valve body, wherein said second and third portions are constructed and arranged to flex in response to pressure forces to alternately open and close said inlet and outlet openings.
8. The combination of claim 7 wherein said seamless solid molded valve body defines a plunger-side surface and an oppositely-disposed second surface and said first portion extends through said seamless solid molded valve body from said plunger-side surface to said second surface.
9. The combination of claim 8 wherein said second portion is positioned against said plunger-side surface.
10. The combination of claim 9 wherein said third portion is positioned against said second surface.
11. The combination of claim 10 wherein said inlet opening includes a shelf.
12. The combination of claim 7 wherein said seamless solid molded body defines a control valve opening.
13. The combination of claim 7 wherein said unitary valve panel is comprised of a plastic or composite material.
14. A unitary reed valve for controlling the incoming and exiting fluid flow through a fluid priming pump, said unitary reed valve comprising:
a seamless solid molded valve body defining an inlet opening and an outlet opening, the inlet opening comprising an inset shelf; and
a unitary valve panel having a first portion molded within said seamless solid molded valve body, a second portion cantilevered over said inlet opening and a third portion cantilevered over said outlet opening, the seamless solid molded valve body enveloping the first fixed portion of the unitary valve panel such that the first fixed portion of the unitary valve panel is surrounded by the seamless solid molded valve body, wherein said second and third portions are constructed and arranged to flex in response to pressure forces to alternately open and close said inlet and outlet openings.
15. The unitary reed valve of claim 14 wherein said seamless solid molded valve body defines a plunger-side surface and an oppositely-disposed second surface and said first portion extends through said seamless solid molded valve body from said plunger-side surface to said second surface.
16. The unitary reed valve of claim 15 wherein said second portion is positioned against said plunger-side surface.
17. The unitary reed valve of claim 16 wherein said third portion is positioned against said second surface.
18. The unitary reed valve of claim 14 wherein said seamless solid molded valve body defines a control valve opening.
19. The unitary reed valve of claim 14 wherein said unitary valve panel is metal.
20. In combination:
a fluid priming pump including a pump body and a movable plunger positioned within said pump body; and
a unitary reed valve positioned adjacent said pump body for controlling the incoming and exiting fluid flow through a fluid priming pump, said unitary reed valve comprising:
a solid molded valve body defining an inlet opening, a control valve opening and an outlet opening, the inlet opening comprising an inset shelf; and
a unitary valve panel having a first portion molded within said solid molded valve body, a second portion cantilevered over said inlet opening and a third portion cantilevered over said outlet opening, wherein said second and third portions are constructed and arranged to flex in response to pressure forces to alternately open and close said inlet and outlet openings.
21. The combination of claim 20 wherein said solid molded valve body defines a plunger-side surface and an oppositely-disposed second surface and said first portion extends through said molded valve body from said plunger-side surface to said second surface.
22. The combination of claim 21 wherein said second portion is positioned against said plunger-side surface.
23. The combination of claim 22 wherein said third portion is positioned against said second surface.
24. The combination of claim 20 wherein said unitary valve panel is metal.
