A brake disk includes at least one friction ring, which includes a base member. The brake disk also includes at least one hole and/or groove located in the friction ring. The brake disk also includes at least one coating, which is applied to at least portions of the friction ring. The coating comprises at least portions of the transition between the hole and/or groove and the friction ring. At least portions of the transition between the hole and/or groove and the friction ring are constructed to be rounded and/or chamfered in a flat manner.

Brake disk and method for producing a brake disk

A gray cast iron brake disk has a thermally applied wear-reducing surface coating containing chromium and/or tungsten carbides. The surface coating has a roughness reduced to about 0.5 to 1 &#x3bc;m to shorten a wearing-in period.

Brake disk

A fuel supply system, having a housing, in which a pistonlike element is disposed longitudinally displaceably in a bore and is guided sealingly in the bore by a guide portion. On one end, the guide portion adjoins a first fuel-filled chamber, and on its other end it adjoins a second fuel-filled chamber. At least one recess extending at least approximately in the circumferential direction is embodied in the guide portion of the pistonlike element and extends over at least part of the circumference of the pistonlike element and, viewed in the longitudinal direction of the pistonlike element, has an asymmetrical cross section.
