    Abstract: A four-cycle internal combustion engine with a valve system having improved durability in the case of high revolution speed. The engine includes a cylinder head having a port, and a valve having a stem part continuous with a fillet part for opening or closing the port. A valve spring including inner and outer springs urges the valve in a direction to close the port. A valve guide holds the stem part slidably. A tubular spring guide supports an outer periphery part of an outer spring to prevent lateral deformation of the spring. A top end of the spring guide is positioned above a top end of a valve guide.

    Abstract: A valve resting mechanism, for use with an internal combustion engine, which is capable of facilitating assembly of a valve lifter in the valve device. A valve device having a valve resting mechanism used for an internal combustion engine is configured such that a valve lifter having a lost motion mechanism is interposed between a cam and a stem of a poppet valve; the valve lifter is usually biased by a lifter spring in the direction in which the valve lifter is engaged with the cam; and a peripheral groove is provided for introducing hydraulic pressure for driving the lost motion mechanism is formed in an inner peripheral surface of a valve lifter hole for slidably guiding the valve lifter. In this valve device, the valve lifter, the lifter spring, and the peripheral groove are formed in such a manner that a lower end A of the valve lifter is positioned under a lower end of the peripheral groove in a state in which the lifter spring is freely extended.

    Abstract: A method of producing a valve lifter to be used in a valve operating mechanism of an automotive vehicle. The valve lifter includes a skirt section, a crown section formed one end of the skirt section so that a cam of a camshaft is slidably contactable with the crown section, and a contacting section formed at an inside surface of the crown section and contactable with a valve stem of an engine valve. The production method comprises the following steps in the sequence set forth: (a) cold-forging a base material to form a valve lifter-shaped base material; (b) cold-pressing the base material to shape the valve lifter-shaped base material; (c) grinding an outer surface of the valve lifter-shaped base material to trim an outer shape of the valve-lifter-shaped base material; (d) totally machining the outer surface and an inner surface of the valve-shaped base material to adjust dimensions of parts of the valve lifter-shaped base material; (e) heat-treating only a part of the valve lifter-shaped base material, corresponding to the contacting section, to increase a hardness of the contacting section; and (f) grinding the contacting section to finish the contacting section.

    Abstract: A combination of an adjusting shim and a cam used in a valve train in an internal combustion engine for automobiles, the adjusting shim composed of a ceramic material which sets the surface roughness of a sliding surface of the adjusting shim with respect to a cam to not more than 0.1 .mu.m in ten-point mean roughness Rz, and which contains not less than 60 vol. % of silicon nitride or sialon, and the cam composed of cast iron a surface of which is chill hardened and then provided with a phosphate film thereon. The combination of an adjusting shim and a cam is capable of smoothing a sliding surface of the cam by the break-in of the part even if the cam is not subjected to a super-precision finishing process; preventing the seizure and abnormal abrasion of sliding surfaces; stabilizing a smoothed condition of the sliding surfaces of the cam and shim for a long period of time; and providing excellent sliding characteristics of the sliding surfaces owing to a decrease in the friction coefficient thereof.
