Latest Patents
One of his latest inventions is a two-stroke engine designed specifically for portable handheld work apparatuses, such as motor-driven chain saws. This innovative engine features a cylinder housing and a crankshaft journalled in shaft bearings. The cylinder housing is sealed with a crankcase cover, and half shells are integrated into both the cylinder housing and the crankcase cover to accommodate the shaft bearings. Overflow channels are strategically formed in the wall of the cylinder, leading from the crankcase to the combustion chamber. These channels are open at their ends facing the crankcase cover and interrupt the support surface of the half shells. This design ensures adequate support for a small crankshaft bearing, allowing for the arrangement of multiple overflow channels. The half shells are configured with a significantly larger diameter than the outer diameter of the shaft bearing, and a support shell is positioned in the space between the half shell and the shaft bearing. This innovative approach effectively closes the gaps in the support surface of the half shells.
