ABSTRACT:
A decompression brake for commercial vehicles, including a hydraulic mechanism that during the compression stroke, in the zone of the ignition-upper dead center position, holds the exhaust valve of the Diesel engine slightly open. The hydraulic mechanism is formed by: an actuating cylinder that controls the exhaust valve and includes an actuating piston, a control line, and a transmitter cylinder that has a transmitting piston. To provide a simpler construction of the hydraulic system, the injection pump that is inherent to the engine is itself used as a controlled transmitter cylinder and piston.
