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.

Claim (Index 20):
A valve train for a reciprocating piston internal combustion engine, comprising:\n a crankshaft; at least one inlet valve and 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 the first camshaft; at least one brake cam held on the first camshaft; at least one inlet cam follower, which actuates the at least one inlet valve and is drive-connected at least at times to the inlet cam; at least one outlet cam follower, which actuates the at least one outlet valve, is drive-connected at least at times to the outlet cam, and, in a braking mode, is drive-connected at least at times to the brake cam; a phase shifting device for adjusting a phase position of the brake cam relative to the crankshaft; and at least one of a connecting apparatus and a switchover apparatus, each being switchable over between a braking position, in which the cam follower is drive-connected to the brake cam and the outlet cam, and a normal position, in which the outlet cam follower is drive-connected only to the outlet cam; wherein the first camshaft and the second camshaft each has a hollow shaft and an inner shaft, which runs in the hollow shaft, the hollow shaft and the inner shaft being rotatable relative to one another by way of the phase shifting device.
