Abstract
Abstract A braking device for a four-cycle engine of a vehicle, particularly for an internal combustion Diesel engine, with a motor brake adjustment member which is connected with a shutoff element in the exhaust conduit and with a control element in a pressure conduit. Pressure cylinders are associated with the exhaust valves and are connected to the pressure conduit after the control element. Compensating pistons are respectively connected with the valve shafts and are subjected to pressure in the pressure cylinders for closing the exhaust valves. The motor brake adjustment member has a first adjustment range for actuating the shutoff element, and a second adjustment range for actuating the control element.
