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. A manifold comprising:
a body of at least two sections that are joined together to form first and second chambers on either side of a separating wall;
a first recess formed in a first of the at least two sections at a first predetermined distance from the separating wall;
a second recess formed in a second of the at least two sections at a second predetermined distance from the separating wall;
a plurality of vent holes are formed in the separating wall around a central opening that is dimensioned to receive a first portion of a check valve;
the check valve has the first portion positioned in the central opening and a second portion that overlies the plurality of vent holes in the separating wall; and,
a check valve retainer with a first end having a first retainer portion and a second retainer portion, the first retainer portion is dimensioned to be received within the first recess and the second retainer portion is dimensioned to be received within the second recess, and a second end that is spaced from the first end and maintains the first portion of the check valve in the central opening.
2. The manifold of claim 1 , wherein the retainer has a first shoulder and a second shoulder, the first shoulder is received in the first recess and the second should is received in the second recess.
3. A manifold comprising:
a body of at least two sections that are joined together to form first and second chambers on either side of a separating wall, one of the first and second chambers is a PCV chamber and the other is an intake chamber;
a recess formed in at least one of the at least two sections at a predetermined distance from the separating wall;
a plurality of vent holes are formed in the separating wall around a central opening that is dimensioned to receive a first portion of a check valve;
the check valve has the first portion positioned in the central opening and a second portion that overlies the plurality of vent holes in the separating wall; and,
a check valve retainer with a first end dimensioned to be received within the recess and a second end that is spaced from the first end and maintains the first portion of the check valve in the central opening.
4. A manifold comprising:
at least two body sections that are joined together to define a first chamber, a second chamber, and wall separating the first chamber from the second chamber;
a recess formed in at least one of the at least two body sections at a predetermined distance from the wall;
a plurality of vent holes located in the wall around a central opening;
the check valve has a first portion positioned in the central opening and a second portion that overlies the plurality of vent holes; and,
a check valve retainer with a first end that is received within the recess and a second end that is spaced from the first end and maintains the first portion of the check valve in the opening; and,
the manifold and the retainer are molded of PA6 (nylon 6) with 30% Glass Fill.
