摘要： An engine cooling device comprises an oil jacket surrounding a cylinder portion of an engine, an oil gallery supplying high-pressure oil to various parts of the engine, and an oil pressure regulator disposed between the oil jacket and the oil gallery to reduce the pressure of the high-pressure oil supplied from the oil gallery and to supply the oil at a reduced pressure to the oil jacket. Thus, the required mechanical strength of the oil jacket can be decreased to decrease the weight of the engine cylinder block.

摘要： An intake port device comprises an intake port (9) formed by a straight part (13) and a helical part (15), and a valve (17) disposed adjacent to the inlet of the intake port. In order that intake air flow having a large swirl ratio can be supplied to an engine without being encountered with a large resistance even in a light-loaded condition of the engine, the valve (17) is held in its closed position without causing any sharp decrease in the coefficient of intake air flow when closed. In a modification of the intake port device, the valve (17) holds open the lower half of the intake port 9 in its closed position, so that intake air flow having a large swirl ratio can be supplied without being encounted with a large resistance even when the load of the engine is light. In another modification of the intake port device, the free end of the valve (17) is bent and deformed in the downstream direction of intake air so that the flow of intake air may not be encountered with a large resistance.

摘要： A device for varying the effective intake passage length of an internal combustion engine having a compact and simplified structure. A cylindrical rotor is rotatably mounted coaxially within a hollow cylindrical casing. A chamber formed within the rotor is communicated with the air filter of the engine, while a second chamber, defined between the inside of the casing and the outside of the rotor, is communicated with the intake chamber of the cylinders of the engine. A partition extends between the inner wall of the casing and the outer wall of the rotor. By turning the rotor, the effective air intake passage length is varied, thereby allowing the combustion efficiency to be maximized.

摘要： In a cooling apparatus for an engine, a water jacket is divided into two parts, namely a forcible circulation part located chiefly round a cylinder head, and a natural convection part located chiefly round a liner of a cylinder block. The natural convection part is filled at its upper space with a cooling water and at its lower space with a cooling medium different from the cooling water. The cooling medium has a boiling point around a temperature zone to cool the liner, and also has a specific gravity larger than that of the cooling water and immiscible with the cooling water.

摘要： The disclosed pump includes a casing housing a working chamber and an impeller. The impeller includes a blade wheel mounted on a rotational shaft, a plurality of pumping blades extending axially from the periphery of the blade wheel and a cover mounted within the casing and fitted over the blade wheel for rotation therewith. The cover includes an end face member defining one side of the working chamber and a cylindrical skirt portion depending from the periphery of the end face member and encircling the blade wheel and defining a hollow interior space within the impeller between the end face member and the blade wheel. The end face member has a plurality of slots through which the blades extend into the working chamber. The interior surface of the cover defines a plurality of pockets, each contoured to receive and mate with one of the blades so that in use each blade rests flush against one surface of the pocket with no space for fluid therebetween.
