Abstract: A tappet in a direct acting type valve operating mechanism of an internal combustion engine comprises a top wall and a cylindrical portion. The upper and lower surfaces of the top wall contacts a rotary cam and the end of a stem of an engine valve respectively. A hard metal layer is formed at the upper and lower surfaces of the top wall to increase strength thereof, thereby increasing wear resistance and durability of the tappet.

Abstract: A tappet for a switchable valve includes a switching device having a clutch member which can be displaced by a hydraulically acted-upon piston and by means of which the valve is switched off in a second switching position and is activated in a first switching position. In order to permit low-friction defined switching movements of the clutch member and the tappet, the clutch member is in each case locked by means of a respective locking device in its end positions assigned to one switching position respectively. The locking device is operative in the respective end position of the clutch member and can be unlocked by the valve stem.

Abstract: A valve actuation assembly is disclosed for use on an internal combustion engine. The assembly includes a cam follower having a follower body. The follower body has an upper head portion and is configured to receive a pair of spaced rollers therein. The rollers are mounted on shafts in the follower body and extend outwardly from the head portion to engage corresponding spaced cam surfaces of a rotatable camshaft for actuating the valve lifter and, consequently, an associated engine valve. The head portion of the follower body cooperates with the inner sidewalls of the rollers to define a space therebetween for straddling a radially outwardly extending spacer mounted for rotation on the camshaft between the spaced cam surfaces. The side surfaces of the outwardly extending spacer are operable with corresponding sidewalls of the rollers to prevent rotation of the cam follower relative to the camshaft.

Abstract: A valve gear device includes a stem having one end and the other end, an intake and exhaust valve connected to the other end of the stem and serving for opening and closing a port formed in a cylinder block of an internal combustion engine, a first spring biasing the stem toward a closing condition of the intake and exhaust valve, a cam, and a valve control device interposed between the cam and one end of the stem, the valve control device having a first member fitted in the cylinder block so as to be slidable along an axis of the stem and engaged with the cam, a second member receiving one end of the stem and movable within the first member relative thereto and a regulating device for permitting and preventing the movement of the second member relative to the first member. Such a structure enables that the top end of the stem is out of sliding engagement with any of related members, thereby preventing a friction wear of the top end of the stem.

Abstract: To manufacture an Al alloy tappet in an internal combustion engine, an intermediate which has a circular upper wall and a cylindrical skirt is formed in the first forging step. In the second forging step, a recess is formed on the lower surface of the upper wall. Relatively large-sized metallic structure in the first forging step is finally collapsed, thereby increasing strength and rigidity of the upper wall around the recess.

Abstract: The invention relates to a valve control system for a push-rod internal combustion engine. The valve control system includes a cam including a rotatable cam shaft having a first cam member and a second cam member having a different profile from the first raised portion. A reciprocating movement is transmitted by a rocker arm engaging the valve and a push-rod connected to a first cam follower in engagement with a push-rod operating a rocker arm and a second follower capable of movement relative to the first cam follower with locking device to enable the cam follower members to be linked so as to be moved together. When the cam follower members are not linked, the valve is controlled by the first cam follower in engagement with and following the profile of the raised portion and when the cam follower members are linked, the valve is controlled by the second cam follower in engagement with and following the profile of the second cam member, thus allowing the selection of one cam or another to accommodate different operating conditions of the engine.

Abstract: A method of manufacturing a tappet used in a valve operating mechanism of a direct acting type in an internal combustion engine. A tip engaged with a center bore of an inner upper surface of a tappet body includes upper and lower convex surfaces and a rounded upper circumferential corner having a certain curvature. thereby preventing concentration of stress even if the tip is subject to high compression load. Thus, durability and reliablity of the tappet are increased.
