ABSTRACT:
This invention relates to an internal combustion engine comprising: a combustion chamber having at least one rigidly fixed inner wall surface and at least two movable inner wall surfaces reciprocally mounted and adapted to reciprocate from a first position lessening the internal volume of the combustion chamber to a second position expanding the internal volume of the combustion chamber; the two movable, inner wall surfaces are adapted to remain in the first position lessening the internal volume of the combustion chamber of a crankshaft means operatively attached to each of the movable, inner wall surfaces; a spark plug secured in the combustion chamber and having the spark gap terminals thereof extending into the combustion chamber; and a pair of inlet and exhaust valves disposed in the combustion chamber and opening inwardly thereinto complete the major components of the novel engine. In another embodiment, a conformable member is provided which acts upon a contained fluid to obtain work from the combustion of fuel. In yet another embodiment, the combustion chamber has at least three movable inner wall surfaces reciprocally mounted and adapted to reciprocally move as described above. Means are provided for translating the reciprocal linear motion of the walls into rotary motion suitable for coupling into a crankshaft.
