A mechanical roller tappet (,) comprising a tappet housing (,) shaped out of sheet metal, a drive roller () actuable by a cam () and an axle (,) on which the drive roller () is mounted, end portions () of the axle (,) being supported in axle eyes () of the tappet housing (,), said tappet housing (,) comprising a tappet skirt (,) and a tappet bottom () possessing a contact surface () for an adjacent engine component on a power take-off side and at an end of the tappet skirt facing the cam, the tappet bottom is connected to the tappet skirt and is shaped into the interior of the tappet skirt while forming a pocket for receiving the drive roller, the axle eyes being arranged in first sections () of the tappet bottom while being spaced from an inner peripheral surface () of the tappet skirt and extend substantially parallel to the longitudinal direction of the tappet skirt, the contact surface being arranged on a second section () of the tappet bottom connecting the first sections to each other.

Mechanical roller tappet for an internal combustion engine

A mechanical tappet () is provided, in particular for actuating the lifting of a pump piston () of a fuel pump of an internal combustion engine, with a sleeve-shaped tappet housing () constructed as a shaped sheet-metal part and with a driving roller () supported so that it can rotate. Here, a bolt () supports the driving roller so that it is centered, and end sections () of the bolt projecting from the driving roller are supported in bolt eyes () of the tappet housing.

Mechanical tappet in particular for a fuel pump of an internal combustion engine

The friction clutch between the prime mover and the change-speed transmission in the power train of a motor vehicle is actuatable by a slave cylinder cooperating with a master cylinder wherein the piston is movable by a clutch pedal or by an electric actuator. The casing of the slave cylinder is made, at least in part, of a plastic material and defines a plenum chamber arranged to receive pressurized fluid from the master cylinder by way of a conduit extending through a bell which contains the clutch and the slave cylinder. The annular piston of the slave cylinder surrounds the input shaft of the transmission. The plastic material of the casing of the slave cylinder can contain one or more additives which enhance its strength and/or influence its frictional engagement with the adjacent surfaces of the piston or of a lip seal which reciprocates with the piston. The piston and/or the lip seal can be installed in the casing to contact one or two metallic or plastic guide sleeves which are connected to or form part of the casing.
