Abstract
In a revolving piston device that is used to make a four stroke internal combustion engine, revolving piston pairs (22, 23, 24, 25) are made to complete two cycles of one compression phase and one expansion phase each. The openings (2-7, 10-17, 34-36) on components of revolving piston device are made in such a way that an opening can be used for multiple flow passages to reduce unutilised space within controlled active volume that reduces unutilised expansion of gases or air within controlled active volume during respective power stroke. This also reduces loss of fresh gases trapped within the openings to exhaust manifold. This invention describes how to use same opening on various components of a revolving piston device for multiple flow passages to reduce overall losses.
Claims15
A revolving piston device, comprising at least one fixed circular ring, in which at least one piston pair revolves around an axis of the fixed circular ring;
- wherein one piston of the piston pair is a portion of and connected to a first revolving assembly and the other piston of the piston pair is a portion of and connected to a second revolving assembly, the space between the two pistons of the piston pair acts as controlled active volume;
- wherein the two revolving assemblies and thus the pistons connected to it, revolve with varying relative speed;
- wherein this variation in relative speed between the two pistons of a piston pair causes expansion and compression of the controlled active volume as one of the revolving assemblies is some times slower and some times faster than the other revolving assembly;
- wherein one of the two revolving assemblies drives the other through positive drive that includes a linkage that is mounted on fixed axes and governs the variation in relative speed of one revolving assembly with respect to the other and revolve both the revolving assemblies in same direction, and wherein an output shaft is connected to one of the two revolving assemblies;
- characterised in that at least one of the openings provided on any component of the revolving piston device is used for one flow passage for some time and for some other flow passage for some other time during revolutions of revolving piston pair.
