Abstract: A radial roller bearing, which has an outer bearing ring and a multiplicity of cylindrical roller bodies which roll on the inner lateral surface of the outer bearing ring and the outer lateral surface of an inner bearing ring or a shaft. The roller bodies are held at uniform intervals by a bearing cage with inwardly directed radial rims for axial guidance. Lubricating openings, which lead from the outside into the bearing interior, supply lubricant, and are arranged on the outer or inner bearing ring axially at both sides. The lubricating openings are cutouts which are formed into one or both axial sides of the bearing rings, outside a load zone of the bearing rings, which extend into the outer or inner raceway of the roller bodies and in which the roller bodies are arranged so as to be partially freely accessible for receiving oil form the bearing surroundings.

Abstract: A coupling device (1) of a switchable cam follower (2), in which a borehole (9) extends above a contact (8) for a support element in an outer lever (3) of the cam follower (2), and this borehole has a first section (10) of large diameter that starts from an outer side (11) of a crosspiece (6) on the other end (7) to which connects to a second section (12) of accordingly smaller diameter up to directly before an inner side (13) of the crosspiece (6). A smooth cylindrical coupling slide (14) is guided in a sealing manner through the second section (12), and this coupling slide projects with a sub-region (15) into the first section (10). This sub-region (15) is encompassed by a compression spring (16) that acts, on one end, against an annular end (17) formed between the sections (10, 12) and, on the other end, against a catch element (19) arranged on the lateral surface (18) of the sub-region (15). The first section (10) is closed by a thin-walled plug (20), such that a pressure space (22) for hydraulic medium is located axially between the annular end (17) of the borehole (9) and an inner side (21) of the plug (20), and for a coupled case, the coupling slide (14) can be brought into contact by hydraulic medium that can be guided into the pressure space (22) before its outer end (23) with a sub-region (25) extending on its inner end (24) with a catch surface (26) of a cross region (27) of the inner lever (4) and, for a decoupled case, the coupling slide (14) can be displaced in the direction toward the plug (20) such that it is out of contact from the catch surface (26) for a switched-off/reduced hydraulic medium pressure via the compression spring (16).

Abstract: A switchable finger lever (1) for a valve drive of an internal combustion engine is provided. The inner lever (3) of the finger lever includes a piston (6) on one end thereof, that can be longitudinally displaced, and acts as a coupling element. The coupling element can be partially brought into contact with a driving surface (7) of an outer lever (2), and is provided, for example, with a rising radial profile (13) in the coupling region thereof, and from the front (12) in the coupling direction. The driving surface (7) of the outer lever (2) also has a conical contour which follows the profile (13). During coupling, a contact point (K) of the piston (6) is located on the driving surface (7) in a region of half a depth thereof. In this way, the formation of undesired edge supports is prevented during coupling.
