摘要： The invention proposes a switchable roller tappet (1) for transmitting a cam lift to a push rod. According to the invention, the inner and the outer rotation-preventing devices of the tappet are made as a single component (17). This component is arranged in a reception (13) of the inner element (4), which reception also serves to lodge a coupling means (24). A tappet (1) of this type can be economically manufactured.

摘要： The invention concerns a mounting and anti-rotation device (mounting aid) (1) for roller tappets of a valve train of an internal combustion engine in which gas exchange valves are activated by roller tappets. The roller tappets comprising a substantially cylindrical tappet body are retained in receptions (7, 8) of the mounting aid (1) that is made of plastic. With the help of opposing parallel anti-rotation surfaces that are arranged symmetrically to the longitudinal axis of the roller tappet and are disposed on the end of the tappet body that is oriented away from a roller, the roller tappets are guided secured against rotation in the mounting aid during the operation of the internal combustion engine. This is achieved by the fact that the inner profile of the receptions (7, 8) is matched to the outer profile of the roller tappets. To avoid mixing up the switchable with the non-switchable roller tappets during assembly, the distances between the anti-rotation surfaces on the different roller tappets, and thus also the inner contours of the corresponding receptions (7, 8) are chosen so as to differ markedly from each other. To achieve the correct orientation of the switchable roller tappets, for example, relative to an oil gallery, the anti-rotation surfaces of the switchable roller tappets and the corresponding receptions (8) of the mounting aid (1) are arranged asymmetrically to the longitudinal axis of the tappet body and comprise a groove (32) or a rib (35), respectively.
