Abstract
A valve train for actuating gas exchange valves of an internal combustion engine may include a first camshaft that is received such that it can be rotated in a first shaft axis, and a second camshaft that is received such that it can be rotated in a second shaft axis. At least one of the camshafts may be configured as an adjustable camshaft that comprises an outer shaft in which an inner shaft is received such that it can be rotated. At least one of the camshafts may be drive-connected via a drive means to a crankshaft of the internal combustion engine. A phase shifting member may be provided by way of which the phase position of at least one inner shaft can be changed relative to the phase position of at least one outer shaft of the camshaft. The phase shifting member may comprise an arrangement that is spaced apart from both shaft axes.”
