Abstract
The invention relates to an internal-combustion engine-braking device and comprises a throttle valve actuated by a control piston both of which are arranged in a controlled bore in a cylinder head. To ensure lubrication of the control piston in a simple way, the control bore is equipped with a connecting orifice to the oil return bore leading from the engine rocker-arm space into the crankcase.
