を特徴とするデイーゼル機関の掃気装置。 In a crosshead type two-stroke diesel engine equipped with a scavenging air control valve that opens and closes the scavenging air hole, a partition wall is provided in the scavenging air reservoir formed around the scavenging air hole so that the lower surface of the piston faces and the scavenging air is controlled through the on-off valve. The partition wall defines a scavenging pump chamber which is communicated with the scavenging air reservoir and becomes a sealed space when the scavenging control valve closes the scavenging hole, and the scavenging pump chamber is communicated with the scavenging passage from the supercharger via a check valve. A scavenging device for a diesel engine characterized by:
