FIELD: engines and pumps.
SUBSTANCE: system for actuation of engine exhaust valve for engine braking includes rocker axle 101, engine braking rocker 100, baffle 300 of valves, sliding pin 310, cam 200 and spring 124. Rocker axle 110 has inlet passage 112 for control fluid. Engine braking rocker 100 is fitted on rocker axle 110 and has central bore arranged around axle 110, fluid passage communicating central bore with control valve 130, and fluid passage 105 communicating control valve with drive piston assy 120. Valve baffle 300 extends between engine first and second exhaust valves 400. Sliding pin 310 is located in said baffle 300 and contacts with engine first exhaust valve 400. Drive piston assy 140 comes in contact with sliding pin 310. Cam 200 serves to transfer engine brake drive motion to rocker 100. Spring 124 brings rocker 100 in contact with cam 200. Invention covers also engine valve actuation.
EFFECT: higher efficiency of braking.
