An air spring, comprising:
- a sleeve defining a chamber expandable and compressible along an axis;
- a jounce bumper fixed relative to the sleeve in the chamber;
- a bump cap moveable relative to the jounce bumper along the axis from a first position to a second position, the bump cap spaced from the jounce bumper along the axis in the first position and in contact with the jounce bumper in the second position;
- and
- the jounce bumper including a valve moveable by the bump cap along the axis to a closed position when the bump cap moves to the second position;
- wherein the valve includes a cap and a base slidably engaged with the cap, the base slidable along the axis relative to the cap between an open position and the closed position;
- wherein the cap includes an intake extending parallel to the axis and the base includes a plurality of exhausts spaced from each other circumferentially about the axis, the intake and the exhausts are in fluid communication with each other when the valve is in the open position.
