Abstract
549,313. Lubricating. SCOTT MOTORS (SALTAIRE) Ltd., and CULL, W. June 24, 1941, No. 7921. [Class 7 (ii)] [Also in Group XXXIV] In a multi-cylinder two stroke internalcombustion engine, the main bearings of the crankshaft function as rotary valves to connect the oil drainage well of one cylinder under crankcase compression with the big end bearing of another cylinder under crankcase suction, a well being formed at the base of each cylinder wall. Each cylinder 1 has an annular well 2 to collect the lubricant which separates out from' the firing mixture, and this well leads by a duct 3 in the housing 4 and its liner to a crescent shaped chamber 6 in the liner which surrounds a porous sleeve 5 of sintered bronze. This sleeve has a port 7 which leads to a port 11 in the journal 8 and ducts 9, 12 connected through the crankshaft to the big-end bearing on the crank in the adjacent cylinder. The main bearing at the end of the journal has a return connection from its duct 3 to the first main bearing. Excess oil escapes by duct 18 to the engine sump 17 and to auxiliary lubrication points such as the clutch spindle bearing.
