A gas compression system is disclosed that includes a hollow cylinder having a cylinder wall, a reciprocal piston carried within the cylinder, and a piston rod connected to the piston. Gas compression control within the cylinder is determined by providing at least two closable openings through the cylinder wall that become closed as the reciprocal piston approaches top dead center within the cylinder. The spacing of the openings is preferably diametrically opposite one another. |
