Assembly and method for controlling an air intake runner
View Patent ↗A subassembly for a valve device for controlling air flow in an intake manifold. The subassembly includes a cartridge including a plurality of compartments having partially open opposing sidewalls, wherein adjacent partially open side walls of adjacent compartments are spaced apart a distance to define a groove therebetween, a plurality of partitions each having a through-hole therein and being disposed in the grooves defined between adjacent partially open side walls of the adjacent compartments. The partitions complete the formation of the opposing side walls of the adjacent compartments and each compartment is alignable with an air intake runner of an intake manifold.
1. A subassembly for a valve device for controlling air flow in an intake manifold, the subassembly comprising:
a cartridge including a plurality of compartments having partially open opposing sidewalls, wherein adjacent partially open side walls of adjacent compartments are spaced apart a distance to define a groove therebetween;
a plurality of partitions each having a through-hole therein, the partitions being disposed in the grooves defined between adjacent partially open side walls of the adjacent compartments, wherein the partitions complete the formation of the opposing side walls of the adjacent compartments;
wherein each compartment of the cartridge is alignable with an air intake runner of an intake manifold.
2. The subassembly of claim 1 , further comprising a plurality of flaps each having a through-slot for receiving a shaft, wherein each flap is disposed within one of the plurality of compartments.
3. The subassembly of claim 2 , further comprising a shaft capable of rotating the flaps, the shaft being inserted through the through-holes in the partitions and the through-slot in the flaps.
4. The subassembly of claim 3 , wherein each flap includes a connecting portion having an opening with a non-round cross-section and the shaft has a cross-section substantially equivalent to the non-round cross-section of the opening of the connecting portion of each flap.
5. The subassembly of claim 1 , wherein the partitions are snap-fit into the grooves of the cartridge.
6. The subassembly of claim 1 , wherein the partitions are formed of or include a low friction plastic.
7. The subassembly of claim 1 , further comprising a plurality of bushings, wherein the bushings are positionable in the through-holes of the partitions with one bushing per through-hole.
8. The subassembly of claim 2 , wherein, when in a closed position, each flap is shaped to substantially seal the air intake runner aligned with the compartment in which the flap is disposed.
9. The subassembly of claim 8 , wherein each flap includes an outer portion for sealing the compartment in which the flap is positioned, the outer portion being formed from an over-molded rubber material.
10. The subassembly of claim 3 , wherein each flap is slideable along a length of the shaft such that each flap is self-aligning.
11. The subassembly of claim 1 , wherein the grooves of the cartridge are oriented generally transverse to a longitudinal axis of the cartridge and the portion of the cartridge defining the grooves is flexible enough to bend for snap-fitting the partitions therein.
12. The subassembly of claim 1 , wherein the cartridge is formed of or includes a reinforced plastic and the partitions are formed of or include a non-reinforced plastic.
13. A kit for controlling air flow in an intake manifold, the kit comprising:
a cartridge including a plurality of compartments having partially open opposing sidewalls, wherein adjacent partially open side walls of adjacent compartments are spaced apart a distance to define a groove therebetween;
a plurality of partitions each having a through-hole therein, the partitions being receivable in the grooves defined between adjacent partially open side walls of the adjacent compartments to complete the formation of the opposing side walls of the adjacent compartments;
wherein each compartment of the cartridge is alignable with an air intake runner of an intake manifold.
14. The kit of claim 13 , further comprising a plurality of flaps each having a through-slot for receiving a shaft, wherein each flap is disposable within one of the plurality of compartments.
15. The kit of claim 14 , further comprising a shaft capable of rotating the flaps, the shaft being insertable through the through-holes in the partitions and the through-slot in the flaps.
16. The kit of claim 14 , wherein each flap includes a connecting portion having an opening with a non-round cross-section and the shaft has a cross-section substantially equivalent to the non-round cross-section of the opening of the connecting portion of each flap.
17. The kit of claim 13 , wherein the partitions are snap-fittable into the grooves of the cartridge.
18. The kit of claim 13 , wherein the partitions are formed of or include a low friction plastic.
19. The kit of claim 13 , further comprising a plurality of bushings, wherein the bushings are positionable in the through-holes of the partitions with one bushing per through-hole.
20. The kit of claim 14 , wherein, when in a closed position, each flap is shaped to substantially seal the air intake runner aligned with the compartment in which the flap is disposed.
21. The kit of claim 20 , wherein each flap includes an outer portion for sealing the compartment in which the flap is positioned, the outer portion being formed from an over-molded rubber material.
22. The kit of claim 13 , wherein the grooves of the cartridge are oriented generally transverse to a longitudinal axis of the cartridge and the portion of the cartridge defining the grooves is flexible enough to bend for snap-fitting the partitions therein.
23. The kit of claim 13 , wherein the cartridge is formed of or includes a reinforced plastic and the partitions are formed of or include a non-reinforced plastic.
