PURPOSE:To steadily prevent cylinder interior from gas leakage by providing a scavenging control valve which is possible to be intermitted from oblique upper or lower direction to a outside surface of a scavenging port part of a cylinder liner. CONSTITUTION:Scavenging ports 1 in a scavenging engine are provided as piercing a liner at a designated location on a lower part of a cylinder liner 2, further, protruded contact seat 4 is provided on a upper and lower periphery of scavenging ports 1 of the outside surface of the cylinder liner 2. A pair of semicercular scavenging valve 13A, 13B are provided on the outside of the cylinder liner 2 which respectively supported by hydraulic cylinder device 15A, 15B. The hydraulic cylinder device 15A, 15B are provided in inclined state as able to touch and remove the scavenging control valve 13A, 13B toward the scavenging ports 1 from oblique lower direction. Also, virtical part of the contact seat 4a is provided on the lower part of the cylinder liner 2 corresponding to the end part of the each said valve 13A, 13B. |
