摘要： To manufacture a tappet in an internal combustion engine, a tappet rough body which comprises a cylindrical portion with an upper wall and an annular side wall is moulded by press processing of metal powder, such that the upper wall, the cylindrical portion and the annular side wall become larger than the tappet to be manufactured in the axial size. After sintering the tappet rough body, it is re-compressed to form the final tappet.

摘要： A stem and a valve face of an engine valve are ground by first and second grinding wheels respectively. A motor for driving the second grinding wheel is mounted on a first plate movable by a servomotor in a direction perpendicular to the axis of the wheel, and under the first plate, a second plate is disposed to be movable in a direction parallel with the axis of the wheel. The valve face is ground obliquely by the second grinding wheel by moving the two plates. The first grinding wheel is trued by a first dresser movable in directions parallel with and perpendicular to the axis of the first grinding wheel. The second grinding wheel is trued by a second dresser provided at the end of a support strut.

摘要： In a pressure fluid control valve device, the fluid exhausted from an internal combustion engine flows through a pair of paths selectively or simultaneously. Each of the paths is opened and closed by a butterfly valve fixed to a valve shaft. A coupling for connecting the valve shafts across the paths comprises a slitting recess and a projection provided at the opposing ends of the valve shafts respectively. The direction of the surface of the recess and the projection is set to within 30 degrees with respect to the direction of the surface of the valve disc fixed to the valve shaft having the recess. Thus, the corner of the recess is not engaged with the bearing surface which is loaded, thereby making axial length for connecting the valve shafts to zero to manufacture the light and compact device.

摘要： A tappet is used in a valve-operating mechanism of an internal combustion engine. The tappet has a top wall and the upper surface of the top wall is engaged with a cam. The lower surface is engaged on a poppet valve which moves up and down. A downward projection which has a recess for storing lubricating oil is formed in the middle of the lower surface of the top wall of the tappet, thereby lubricating interfaces with the cam or valve to improve frictional or wear resistance.

摘要： A rod material made of Ti alloy has a larger diameter portion at the end, which is joined with the end of material made of TinullAl intermetallic compound, by friction welding, to form a poppet valve for an internal combustion engine. Instead of providing such larger diameter portion, the end of the material made of TinullAl intermetallic compound may be heated to facilitate joining.

摘要： A poppet valve is provided to open and close a valve seat in an internal combustion engine. At the end of a valve stem of the valve, a cylindrical support is fixed, and on the outer circumferential surface of the support, a moving coil is wound. There is formed an annular cavity in a yoke fixed to a bracket fixed on a cylinder head, and a permanent magnet is fixed in the annular cavity of the yoke. Between the permanent magnet and the yoke in the annular cavity, the support which has the moving coil is inserted. By a control system having CPU, an electric current is applied to the moving coil, thereby providing optimum valve timing and lift to decrease seating noise and improving engine performance.
