Definitions

  • the invention is in particular the object of providing a gas exchange valve actuating device, which is insensitive executable in operation against pulses and in which undesirably high forces can be advantageously avoided.
  • the object is solved by the features of patent claim 1, wherein further embodiments of the invention can be taken from the subclaims.
  • FIG. 2 shows an actuator unit of an internal combustion engine brake unit of the gas exchange valve actuating device in the deactivated position
  • FIG. 4 shows the actuator unit from FIG. 2 with the actuator means completely extended
  • the brake rocker arm 24a has, at its end facing the gas exchange valve 10a, a transverse arm 25a which is guided transversely to the brake rocker arm 24a or parallel to the rocker arm axis 23a in the direction of the brake rocker arm 24a.
  • an actuator unit is arranged with an actuator means 12a formed by a hydraulically actuated actuator piston (FIGS. 1 and 2).
  • the actuator 12a is guided in a housing 26a of the actuator unit.
  • the actuator means 12d Before the braking operation is activated, the actuator means 12d is in its lower position as a result of the force acting on the actuator means 12d, or due to the force of a spring (not shown).
