Operation
The engine-brake electro-pneumatic valve (33.01), when actuated permits the passage of the air coming from the four-circuit protection valve (4.03) to the engine-brake actuation cylinder (20.05).
The engine-brake pneumatic cylinder (20.05) operates the engine-brake throttle valve, which is (normally) located in the engine exhaust circuit.
