An axial mechanism for converting between linear reciprocating motion and rotary motion comprises a z-crank shaft, a wobble member rotationally mounted to the angled crank pin of the z- crank shaft, and one or more pistons with a connecting rod between each piston and a pivot joint to the wobble member. In one embo...

A burner (10) for an external combustion engine (E) using liquid or gaseous fuel, the burner (10) being arranged for heat exchange between the inlet air to the burner (10) and the exhaust air from the burner (10). The burner (10) includes an external housing (11), a shroud (21) within this housing (11), which shroud...

A machine includes at least one piston(1) reciprocally movable in a cylinder(2), at least twc balancing rotors (3c, 3d) mounted for oscillating rotational movement about an axis or axes (4) transverse to the axis of motion of thepiston, one balancing rotor having a centre of mass on one side of and another balancing...
