Abstract
Various apparatuses are provided for planetary rotor machines including a plurality of helical rotors and a corresponding manifold. In one example, the manifold includes a head plate to which each of the rotors is rotatably mounted. The head plate includes a fluid flow opening having a center coaxial with a central axis of the machine. The fluid flow opening comprises a plurality of ports that each correspond to one of the rotors. Each of the ports comprises an inwardly curving inner side extending between a starting point and an ending point, a first lateral arcuate side that forms with the inner side a first pointed notch in the head plate, and a second lateral arcuate side that forms with the inner side a second pointed notch in the head plate. The second lateral arcuate side is a mirror image of the first lateral arcuate side. The manifold substantially prevents fluid from bypassing a cavity created by the rotors of the machine.
