Laminated universal effort machine

An effort machine, comprising:

• i. a first shaft;
• ii. a second shaft;
• iii. a power disc joined to the first shaft to rotate with the first shaft, the power disc having a first circumference, a first moment beam extending radially from a first portion of the first circumference, and a second moment beam extending radially from a second portion of the first circumference opposite to the first portion;
• iv. a gate disc joined to the second shaft to rotate with the second shaft, the gate disc having a perimeter that comprises a first partial circumference, a first indentation, a second partial circumference, and a second indentation, such that each of the first partial circumferences and the second partial circumference is adjacent to the first indentation and the second indentation, while being opposite to each other;
• v. a timing apparatus coupled to the first shaft and to the second shaft and configured to control a rotation of the gate disc and the power disc, such that:
• at a first rotational range, the first moment beam is contained in the first indentation;
• at a second rotational range, the first circumference contacts the first partial circumference;
• at a third rotational range, the second moment beam is contained in the second indentation;
• at fourth rotational range, the first circumference contacts the second partial circumference;
• vi. a compression plate, having an inlet, an outlet, and a cavity, the cavity being configured for holding the power disc and the gate disc, the cavity being bounded by:
• a first curved wall centered about the first shaft and having a first end and a second end;
• and
• a second curved wall centered about the second shaft and meeting the first curved wall at the first end of the first curved wall and at the second end of the first curved wall;
• vii. a lower panel below the compression plate and configured to close the cavity from below;
• viii. an upper panel above the compression plate and configured to close the cavity from above;
• wherein the first curved wall is configured such that the first moment beam and the second moment beam are flush with the first curved wall when not in respective ones of the first indentation and the second indentation, wherein the lower panel is flush with bottom surfaces of the power disc and the gate disk, and wherein the upper panel is flush with top surfaces of the power disc and the gate disk;
• wherein the inlet opens into the cavity at a first position on the first curved wall for guiding a fluid from outside the compression plate into the cavity;
• wherein the outlet opens into the cavity at a second position on the first curved wall for guiding the fluid from the cavity outside the compression plate.
