The carrier is in turn surrounded by a ported manifold. The carrier and manifold are adapted for relative rotation one to another such that the cylinders periodically open to the ported manifold.

A valving cam fixed to the manifold housing biases valving lever arms as relative motion between the manifold housing and the carrier is accomplished.
