The present invention is for the kind of power machines, engines, pumps or compressions which have two or more pistons which work against each other preferably with a common combustion chamber or corresponding, in a stationary cylinder and where the power is transmitted to or from a rotating motion without an intermediate crankshaft. The object of the present invention is to make use of the moments of the pistons for further purpose. According to the invention the motions of the pistons are used to compress gas on that side of the pistons which is turned away from the combustion chamber. Behind each piston, i.e. on the piston rod side of the respective piston, there is a delimited space, (64, 65). Preferably the spaces (64, 65) are arranged so that during certain parts of a cycle of operation they are closed by valves of a suitable kind and during other parts of the cycle of operation are opened and allow inflow or outflow of gas. |
