Two stroke motor for use in hand-guided tool e.g. power saw has transfer ports and first transfer port is asymmetrical to second transfer port with respect to central plane of the cylinder

摘要

The two stroke motor has transfer ports whereby the first transfer port (9,10) is asymmetrical to the second transfer port (8,11) with respect to the central plane (36) of the cylinder (32). The central plane has the longitudinal axis (48) of cylinder which separates the discharge outlet (37).
