摘要： In a valve train of an internal combustion engine (18) comprising a switchable, rotationally symmetrical component (1) such as a cam follower, a first body (8) acting as an anti-rotation device and a second body (12) acting as a mounting safety device project beyond the component (1). Due to the additional, second body (12) that acts as a mounting safety device, said component (1) can no longer be installed in bores for non-switchable components, for example, in the same internal combustion engine.

摘要： An engageable cam follower (1) for acting on a pushrod in the valve train of an internal combustion engine is provided. This cam follower (1) includes of a thin-walled hollow cylindrical housing (2) in whose borehole (3) is positioned an internal element (4) axially movable with respect to the housing (2). The housing (2) and the internal element (4) each possess a radial borehole (13, 10) aligned in a relative position to each other. Positioned in the radial borehole (10) of the internal element (4) is a piston (11) having a convex end (14) and movable toward the radial borehole (13) of the housing (2) for coupling the internal element (4) with the housing (2) in the relative position. According to the invention, the borehole (3) of the housing (2) is shaped in the area of the radial borehole (13) of the housing (2) as a flattening (15) extending in the longitudinal direction of the cam follower (1). This has the advantage that with the piston (11) positioned only slightly in the radial borehole (13) and with initial cam lifting, this piston (11) is load-bearing over a considerable portion of its periphery. As a result, removal of material from the piston (11), such as can occur in the state of the art and which can lead to jamming of the internal element (4) in the housing (2), is no longer encountered.

摘要： To provide a valve system for an engine, in which a valve stem for an engine valve is slidably fitted in a guide cylinder provided in a cylinder head. A rocker arm is interlocked to rock with rotation of a camshaft. The rocker arm is also interlocked with the valve stem. With the above construction, local wear, galling, and the like in the guide cylinder can be prevented. Accordingly, the reliability can be improved. A lifter is interposed between a rocker arm and a valve stem. The lifter is formed into a cylindrical shape with a closed bottom and has a diameter larger than an outside diameter of the valve stem. The lifter is fitted in a lifter housing in such a manner as to be slidable in the axial direction of the valve stem. The lifter housing is fixed to a cylinder head.

摘要： A two-cycle, multi-cylinder engine maintains roughly equal temperatures between cylinders, despite differing exhaust efficiencies between the cylinders. Several ways of reducing the temperature of one of the cylinders in comparison to the other are disclosed. One embodiment involves supplying more coolant to the cooling passages around the hotter running cylinder. Other ways involve reducing the compression ratio or retarding ignition timing in the hotter running cylinder in comparison to the other cylinder.

摘要： The present invention provides a mechanism of retaining a rocker lever ball socket on a rocker lever ball. The mechanism provided is a retaining cap which is adapted to fit over and securely engage to the socket through a tab and groove arrangement and is made of a slightly elastic material and includes a restricted opening sized smaller than the fullest diameter of the rocker lever ball. During assembly, the retaining cap first interlocks with the socket by a tab and groove arrangement, and the lever ball is then pushed through the restricted opening. The restricted opening, being slightly elastic, enlarges to allow passage of the ball and retracts to a size smaller than the ball so that it is retained thereon.

摘要： In a switchable support element (1) for a valve train of an internal combustion engine, the lost motion spring (8) of the valve train is made as a torsion spring. This spring is arranged outside of the support element (1) and only the legs and the arms of the spring engage a housing and a head, respectively. In this way, the support element (1) requires no substantially larger design space than non-switchable prior art elements, particularly in axial direction.

摘要： A switchable support element (1) requiring only a small design space. For this purpose, a slide (12) that serves to couple an inner element (6) to an outer housing (3) in the support element (1) is positioned laterally in a housing (2) arranged in the cylinder head (5). At the same time, a bore (8) in the inner element (6) for the slide (12) is made as a pocket bore, the housing (2) being seated through an annular extension (11) directly in a bore (9) of the outer housing (3). The slide (12) can be displaced electromagnetically or hydraulically in at least
