Co-axial crankless engine
First Claim
1. A co-axial crankless engine having:
- at least one cylinder defining a longitudinally extending axis;
a pair of pistons positioned to reciprocate in opposite directions along the longitudinal axis of said cylinder, a space between said pistons defining a common combustion chamber;
a first shaft positioned substantially parallel to and spaced laterally from the longitudinal axis of said cylinder;
a second shaft positioned substantially parallel to and spaced laterally from the longitudinal axis of said cylinder, said second shaft having a longitudinally extending bore through which said first shaft can extend and rotate, each said piston being connected to an axially spaced cam, a first said cam being supported by said first shaft, a second said cam being supported by said second shaft,whereby in use reciprocation of said pistons imparts on respective shafts rotating motion in opposite directions to drive said engine.

Abstract
A co-axial crankless engine (1) having at least one cylinder (3) defining a longitudinally extending axis (XX). A pair of pistons (5, 6) are positioned to reciprocate in opposite directions along the longitudinal axis of the cylinder. A space (7) between the pistons defines a common combustion chamber (70). A first shaft (10) is positioned substantially parallel to and spaced laterally from the longitudinal axis of the cylinder. A second shaft (12) is positioned substantially parallel to and spaced laterally from the longitudinal axis of the cylinder. The second shaft (12) has a longitudinally extending bore (14) through which the first shaft can extend and rotate. Each piston is connected to an axially spaced cam (16, 17). A first cam being supported by the first shaft, a second cam being supported by the second shaft. In use, reciprocation of the pistons imparts on respective shafts rotating motion in opposite directions to drive the engine.
