Abstract
An engine exhaust brake for a motor vehicle operated with an Otto-engine, which upon its engagement causes the closing of the exhaust gas line by means of a throttle device and the opening of the throttle valve controlling the mixture supply; a gas-air mixer is thereby arranged upstream of the throttle valve whose gas supply is controlled by the output stage of a membrane-controlled gas-regulator whose vented side is connected with the atmosphere by way of an air line and preferably also by way of a filter protection; a control valve is also arranged in the air line which is controlled by the engine-brake engaging mechanism and which upon engagement of the engine brake connects the vented side of the output stage of the gas regulator with the engine suction pipe, whose vacuum causes the closing of the gas supply to the gas-air mixer.
