Abstract

A valve train for a reciprocating piston internal combustion engine may include a crankshaft, at least one inlet valve, at least one outlet valve, at least one camshaft coupled rotationally to the crankshaft, at least one inlet cam held on a first camshaft, at least one outlet cam held on one of the first camshaft or a second camshaft, at least one brake cam held on one of the first camshaft or the second camshaft, at least one inlet cam follower, which may actuate the at least one inlet valve and may be drive-connected at least at times to the inlet cam, at least one outlet cam follower, which may actuate the at least one outlet valve, may be drive-connected at least at times to the outlet cam, and, in a braking mode, may be drive-connected at least at times to the brake cam, and a phase shifting device for adjusting a phase position of the brake cam relative to the crankshaft.
