The invention discloses a double arm rocker chamber cover with a labyrinth structure condensing space. The utility model is composed of a shell and an inner container which are welded together to form a rocker chamber cover, and the space sandwich of the outer shell and the inner container forms a labyrinth type oil gas condensing chamber. A fuel inlet is arranged on the surface of the rocker chamber cover, and the air outlet is arranged at the right end of the casing. A through hole is arranged between the outer shell and the inner liner, and a cushion block is arranged, and the bolt passes through the through hole and is fixed with a respirator on the surface of the rocker chamber cover. The boss liner walls are provided with gaps and stamping uplift, the gap between the inner gap and the boss and the shell as the entrance channel of oil and gas. The role of oil and gas in the crankcase and the outside pressure, into the rocker chamber cover between the inner layer and the outer layer of the condensation cavity cooling and adhesion in the rocker chamber cover on the inner wall of the oil droplets along the wall, back to the engine, complete separation of oil and gas. The rocker chamber cover can also be used as a crankcase ventilation device without breathing apparatus. The device occupies less space on the periphery of the engine, but the condensation effect is remarkable. Adaptable to configure many types of engines.
