Abstract: A tappet comprises a foot having a convex cam contact surface and an axially extending hub, a tappet body having a lower body portion with a lower axial bore formed therein to receive the axially extended hub of the foot, and a bearing assembly positioned between the foot and the lower portion of the tappet body. The cam contact surface operates in a frictional relationship with a cam lobe of a rotating cam. The frictional relationship between the cam lobe and the cam contact surface of the foot induces the foot to rotate about the center line of the tappet. The bearing assembly operates to reduce friction as the foot independently rotates axially about a center line of the tappet body.

Abstract: An internal combustion engine has electrically controlled hydraulic linkages between engine cams and engine cylinder valves. If it is desired to skip a cam lobe or to modify the response of an engine cylinder valve to a cam lobe, hydraulic fluid is selectively released from the associated hydraulic linkage to permit lost motion between the cam and the engine cylinder valve. Electrically controlled hydraulic fluid valves are used to produce the selective release of hydraulic fluid from the hydraulic linkages. The mode of operation of the engine can be changed (e.g., from positive power mode to compression release engine braking mode or vice versa), or more subtle changes can be made to modify the timing and/or extent of engine cylinder valve openings to optimize engine performance for various engine or vehicle operating conditions (e.g., different engine or vehicle speeds).

Abstract: In a switchable cam follower (1) comprising an inner element (2) and an outer element (3), with said inner element (2) comprising a hydraulic clearance compensation device (10), a coupling of the two elements (2, 3) is effected by radially extending coupling means (4). These coupling means (4) and the clearance compensation device (10) which is integrated in the inner element (2) are loaded by hydraulic pressure from a cylinder head of an internal combustion engine through separate channels (9, 8). According to the invention, the spring means (5) for the coupling means (4) are configured so that from a hydraulic medium pressure from about 0.6 bars on (idling engine speed), the elements (2, 3) are uncoupled. When a switching engine speed, for example, 3,000 rpm, has been reached, the hydraulic pressure in the channel (9) is reduced to about 0.1 bars by a control valve (11). The coupling means (4) are displaced by the spring means (5) into a coupling position. The two elements (2, 3) are connected physically to each other. At the same time, unchoked hydraulic pressure continues to prevail in the channel (8) so that even with increasing speed of the internal combustion engine, the clearance compensation device (10) is optimally supplied with hydraulic pressure.

Abstract: A valve lifter has a cam follower body with a closed end, or head from which depends concentric inner and outer cylinder surfaces. The inner cylinder surface defines a hollow cylinder having a first, closed end and a second, open end configured to receive a hydraulic lash adjuster, for engagement with the valve of an internal combustion engine. Additionally the inner and outer cylinder surfaces define laterally spaced recesses therebetween for receiving cam engaging rollers supported on transverse shafts extending therein. The shafts are supported at their radially outer ends in openings in the outer cylinder surface and at inner radial ends by abutment with the inner cylinder surface. The cantilevered shafts are thus supported against bending under loads applied by the rollers through the fixing of outer ends in the openings and through frictional interaction of the inner radial ends of the shaft against the inner cylindrical surface of the follower.

Abstract: Between the end of a valve and a valve-operating cam in an internal combustion engine, a valve lifter is inserted. A filler enclosing portion is formed between a shim and the body of the valve lifter. Through an opening from an injector, a filler is introduced into the filler enclosing portion, so that valve clearance is corrected to zero. Differences in valve clearance can be easily corrected.

Abstract: A valve train for internal combustion engines utilizing an inverted bucket tappet with a pivot structure operatively disposed between the tappet and the end of the valve stem allowing the valves to be angulated with respect to each other and to the axis of the cylinder in both the transversal and the horizontal planes of the engine. Accordingly on a multi-valve engine, the valves extend radially from the associated combustion chamber to open and increase space in the center of the cylinder head for spark plugs, injectors, or pre-combustion chambers and so that the combustion chamber can be designed with a hemispherical surface, with tangentially disposed valve heads. The construction allows the use of large valves in conjunction with stronger, better-cooled valve seats and bridges. The tappets can be actuated conventionally by direct-acting overhead camshafts or by rocker arms and "T" bridges.
