Abstract (en)
[origin: EP1854967A2] The head (1) has a variable stroke valve drive (2) with an operating lever (3) that is supported on a sliding path (30) of a crank and on an intermediate unit (7). The lever is pivoted against a force of a spring (10) for stroke adjustment between supporting points of a cam (9), and has a rolling unit (4) with an oscillating pivot point that slides parallel to the sliding path by an adjusting device. An actuator (12) e.g. brushless electric motor, with a cooling medium is arranged in the head over the adjusting device, and has a longitudinal axis (12`) aligned in direction of a cylinder axis.
