  • Patent number: 12006864
    Abstract: An energy transfer machine includes a piston and cylinder. The piston can have a rocking motion as it enters and exits the cylinder, for example due to one being on a rotor and the other on a stator. The piston and cylinder form a primary chamber, and as they move relative to each other can form a seal separating the primary chamber into first and second sub-chambers which then unseals before the piston exits the cylinder. The first sub-chamber may reach a maximum geometric compression ratio, for example for the purpose of compression ignition, before the unsealing of the sub-chambers.

    Abstract: Embodiments for balancing a pulser plate are provided. In one embodiment, a pulser plate includes a plurality of teeth, an indexing gap, and a mass modifier. The teeth of the plurality of teeth define a sensed behavior of the pulser plate. The indexing gap separates a first tooth and a second tooth of the plurality of the teeth. The indexing gap is symmetrical about a first axis on a face of the pulser plate. A second axis defines a proximate side of the pulser plate having the indexing gap and a distal side of the pulser plate. The first axis and the second axes are orthogonal to a pulser plate axis and intersect at a center. The mass modifier includes a first mass modifier on the proximate side of the pulser plate to balance the mass of the pulser plate about the center and does not change the sensed behavior.
