Abstract
A device for the simultaneous actuation of two gas exchange valves (10) of an internal combustion engine by a camshaft (11) rotatably supported in a camshaft bearing (15,16), said device comprising a bridge (3) which, with the interposition of hydraulic valve clearance compensation elements (7), is in contact with valve shaft ends (9) of the gas exchange valves (10), and a guide rail (2) on which the bridge (3) is guided for longitudinal displacement by a linear bearing (5), said guide rail (2) comprising a first oil duct (18) which opens into the linear bearing (5) and a second oil duct (22) implemented in the bridge (3), which connects the valve clearance compensation elements (7) to the linear bearing (5), and the oil passes phase-wise from the first oil duct (18) into the second oil duct (22), characterized in that a third oil duct (21) branches from the first oil duct (18) and opens into the camshaft bearing (15,16).
