Rocker arm-valve drive for gas exchange valve of e.g. multi-cylinder internal combustion engine, has force transmission device designed as swing/rocker arm that is rotatably supported on lever axle with pressurizing medium guiding channel

摘要

The drive has a force transmission device (4), arranged between a cam (2) and a gas exchange valve (8), including a hydraulic lifting equipment (9) with a pressure piston (10) longitudinal displaceable in a cylinder (12). The force transmission device is designed as swing arm or rocker arm, which is rotatably supported on a lever axle (3). The lever axle includes a pressurizing medium guiding longitudinal channel (14) as connecting passage between a pressurizing medium supply unit and a pressure space (13).
