Abstract

The new system is characterized by the fact that the displaced volume and the relative position of the intake, exhaust ports ( 31,30 ), sparkplugs, etc. in relation to the displacers ( 1,1 ′ and 3,3 ), may be varied by modifying the angular and linear distance between the geometric axes of the double crankshaft ( 11 ), allowing this oscillating movement of varying speed, and the geometric axis of the arms ( 6,7 ) attached to the rotor with their respective displacers. By placing the double crankshaft ( 11 ) or the positive displacement machine on a chute ( 13 ) or sliding axes and change by means of a spindle ( 14 ) the distances between the geometrical axes, modify also the level of maximum and minimum distance among the displacer's. By modifying the angular distance between the fixed parts of the chamber and the double crankshaft the position of the intake and exhaust ports is also changed, this alteration can be operated with the system detained or in movement in a manual form or motorized and computerized form.
