No filter no run fluid filtration system
A filter system including a designated filter cartridge having a geometric projection, a flow restriction valve that controls fluid flow out of a filter system, and a priming pump configured to prime the filter. The flow restriction valve. The flow restriction valve includes at least on fluid flow check valve configured to allow the priming pump to prime the filter system.
1. A filter system comprising:
a filter cartridge including a geometric projection therein and defining an interior volume;
a flow restriction valve body housed within the interior volume of the filter cartridge and comprising a flow restriction valve, a first fluid flow check valve, a second fluid flow check valve, a fluid flow inlet, and a fluid flow outlet positioned at the second fluid flow check valve, wherein the first fluid flow check valve and the second fluid flow check valve are formed as part of the flow restriction valve body, the flow restriction valve controls fluid flow out of the filter system and includes an opening keyed to the geometric projection such that the geometric projection engages the opening and actuates the flow restriction valve; and
a priming system body coupled to the flow restriction valve body and comprising a priming pump configured to prime the filter system, a priming system inlet in fluid communication with the fluid flow outlet of the flow restriction valve body, and a priming system outlet;
wherein during normal operation, the first fluid flow check valve is configured to allow fluid to flow out of the flow restriction valve bypassing the priming system body, and during priming operation, the priming pump is configured to prime the filter system by allowing fluid to flow out of the flow restriction valve into the priming system body but not into the flow restriction valve through the second fluid flow check valve, the priming pump incapable of priming the filter system in the absence of the flow restriction valve body.
2. The system of claim 1 , wherein the flow restriction valve comprises a ball and a fluid flow opening keyed to the ball such that, when a fluid pressure forces the ball against the fluid flow opening, fluid flow through the fluid flow opening is restricted.
3. The system of claim 2 , wherein the flow restriction valve comprises a valve seal positioned between the valve ball and the fluid flow opening.
4. The system of claim 2 , wherein the geometric projection extends through the opening and prevents the ball from contacting the fluid flow opening.
5. The system of claim 2 , wherein the flow restriction valve is configured such that substantially no fluid flows through the flow restriction valve in the absence of the filter cartridge.
6. The system of claim 1 , wherein the first fluid flow check valve is an umbrella valve.
7. The system of claim 6 , wherein the umbrella valve includes a plurality of fluid flow openings.
8. The system of claim 1 , wherein the priming pump comprises a plunger.
9. The system of claim 1 , wherein the flow restriction valve body comprises the first fluid flow check valve, the second fluid flow check valve, and at least one additional fluid flow check valve.
10. The system of claim 1 , wherein the flow restriction valve body is connected to the filter system by a snap fit connection.
11. The system of claim 1 , wherein the flow restriction valve further comprises a valve ball retention cage.
12. The system of claim 11 , wherein the valve ball retention cage is connected to the filter system by a snap fit connection.
13. The system of claim 1 , wherein the fluid flow outlet is aligned with the priming system inlet.
14. The system of claim 1 , further comprising a sealing element disposed between the priming pump and the flow restriction valve body.
15. The system of claim 1 , wherein the first fluid flow check valve and the second fluid flow check valve each comprise a valve seat.
16. The system of claim 1 , further comprising a filter housing, the filter housing defining a filter cartridge space in which the filter cartridge is disposed.
17. The system of claim 1 , wherein the filter cartridge is a designated filter cartridge specifically configured for use with the filter system.
18. A filter system comprising:
a filter cartridge defining an interior volume;
a flow restriction valve body housed within the interior volume of the filter cartridge and comprising a flow restriction valve, a first fluid flow check valve, a second fluid flow check valve, a fluid flow inlet, and a fluid flow outlet positioned at the second fluid flow check valve, wherein the first fluid flow check valve and the second fluid flow check valve are formed as part of the flow restriction valve body, the flow restriction valve controls fluid flow out of the filter system;
a priming system body comprising a priming pump configured to prime the filter system, a priming system inlet in fluid communication with the fluid flow outlet of the flow restriction valve body, and a priming system outlet; and
a means for designating an appropriate filter cartridge;
wherein during normal operation, the first fluid flow check valve is configured to allow fluid to flow out of the flow restriction valve bypassing the priming system body, and during priming operation, the priming pump is configured to prime the filter system by allowing fluid to flow out of the flow restriction valve into the priming system body but not into the flow restriction valve through the second fluid flow check valve, the priming pump incapable of priming the filter system in the absence of the flow restriction valve body.
19. The system of claim 18 , wherein the means for designating the appropriate filter cartridge prevents the installation of non-appropriate filter cartridges in the filter system.
20. The system of claim 18 , further comprising a filter housing, the filter housing defining a filter cartridge space in which the filter cartridge is disposed.
