Intake manifold with PCV check valve retainer
An intake manifold with an internal check valve that operates in coordination with a Positive Crankcase Valve has a check valve retainer that is mounted within the manifold and contacts the check valve to maintains the check valve in position and avoid dislodgement.
1. An intake manifold comprising:
a body having an interior wall that is positioned between at least two chambers and includes at least one opening that is between the at least two chambers and is surrounded by a plurality of apertures;
a check valve with a first side that covers the plurality of apertures and includes a nipple that is engaged in the at least one opening; and,
a check valve retainer that contacts a second side of the check valve and retains the nipple in the at least one opening.
2. The intake manifold of claim 1 , wherein the check valve retainer contacts the second side directly opposite the nipple.
3. The intake manifold of claim 1 , wherein the check valve retainer is molded of PA6 (nylon 6) with 30% Glass Fill.
4. The intake manifold of claim 1 , wherein the body further includes an arcuate chamber.
5. An intake manifold comprising:
a body having an interior wall that is positioned between at least two chambers and includes at least one opening between the at least two chambers;
a check valve with a first side that includes a nipple that is engaged in the at least one opening; and,
wherein the check valve retainer is generally “T” shaped and one of the at least two chambers includes an upper surface configured to receive a portion of the check valve retainer.
6. An intake manifold comprising:
a body including a first chamber and a second chamber and one of the first chamber and the second chamber includes an arcuate chamber with an upper surface configured to receive a portion of a generally “T” shaped check valve retainer;
a wall separating the first chamber and the second chamber, the wall including a plurality of apertures formed in a circle around an inner opening;
a check valve that overlies the plurality of apertures and includes a dependent nipple that is engaged with the inner opening; and,
the check valve retainer engages the check valve in a position opposite to the dependent nipple and retains the nipple in the inner opening.
7. The intake manifold of claim 6 , wherein the check valve retainer is molded of PA6 (nylon 6) with 30% Glass Fill.
8. The intake manifold of claim 6 , wherein the check valve further includes a cap.
9. The intake manifold of claim 8 , wherein the cap includes flexible flaps.
10. An intake manifold comprising:
a manifold body having at least two chambers separated by a dividing wall having a plurality of apertures;
a check valve that includes a cap having a first side, a second side and a nipple;
the nipple depends from one of the first side and the second side and is dimensioned to engage with one of the plurality of apertures; and,
a check valve retainer that includes a stem and at least one shoulder and contacts the cap on a side opposite to the nipple and retains the nipple engaged in one of the plurality of apertures.
11. The intake manifold of claim 10 , wherein the retainer is molded of PA6 (nylon 6) with 30% Glass Fill.
12. The intake manifold of claim 10 , wherein the stem is connected to the at least one shoulder at a first end and includes a tip at a second end.
13. The intake manifold of claim 12 , wherein the tip contacts the cap.
14. The intake manifold of claim 12 , wherein the check valve retainer is generally “T” shaped and one of the at least two chambers includes an upper surface configured to receive the at least one shoulder of the check valve retainer.
15. The intake manifold of claim 10 , wherein the cap includes flexible flaps.
