Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To improve fuel consumption and obtain a high output by supplying cooling water through a supplying path, which is another path for supplying cooling water to the water jacket of a cylinder block, in the water jacket of a crankcase. SOLUTION: A introduction pipe 100, disposed in a flow path of a jet pump 30, is divided into two pipes 102, 103 at a branch part 101. One pipe 102 is connected to a introduction pipe 49A of a crankcase 40, and the other pipe 103 is connected to a introduction pipe 82 of an exhaust manifold 80. In a two-cycle engine, since cooling water is supplied through a supplying path 102 which is different from a path 103 for supplying cooling water to a water jacket 57 of a cylinder block 50, the crankcase 40 and the cylinder block 50 are satisfactorily cooled simultaneously. Thus a high output can be surely obtained.

Abstract: PURPOSE:To enable change of strip width and reduce effect of variation of molten metal surface level by dividing pouring basin part into two layers and pouring the molten metal for casting into the upper layer and low m.p. molten metal, which has large sp. gr. and does not solidify with cooling action from rolls, into the lower layer. CONSTITUTION:The molten metal A in the upper layer 8 and the molten metal B in the lower layer 12 in the pouring basin part 7 are stored. A fluid resistant body 13 is arranged at the gap 5 between the facing rolls 2, 3 in the lower layer 12. The molten metals A, B are cooled with the rolls 2, 3 and the metal A is taken out as the strip 4. As the metal B is low m.p., this is held under molten state and the molten metal B caused to flow out to a receiving vessel 17 is returned back to the pouring basin part 7 through a pump 14. By changing depth of the lower layer 12 in the pouring basin part 7, change of the strip 4 width can be executed. As the solidified starting point does not exist on the molten metal surface, the effect of variation of molten metal surface level is a little, and the strip 4 having good quality without involving scum can be produced.
