Zusammenfassung:The invention relates to a valve train (1) for an internal combustion engine and to an internal combustion engine. The valve train has an inlet valve actuation mechanism (20) for the periodic actuation of an inlet valve (24) of the internal combustion engine. The valve train (1) also has a delay element (8), which is in contact with the inlet valve actuation mechanism (20) and which has a hydraulic chamber (12) for delaying a closing movement of the inlet valve (24) by means of a hydraulic medium. The valve train (1) has a hydraulic feed for feeding the hydraulic medium into the hydraulic chamber (12), the hydraulic feed having a control shaft (7), and the control shaft (7) being mechanically driven by the internal combustion engine. The control shaft (7) has an axially extended cavity (10) for the hydraulic medium, and at least one opening (5) for intermittently feeding the hydraulic medium from the cavity (10) to the hydraulic chamber (12). The invention also relates to an internal combustion engine having
