Document Type and Number:
WIPO Patent Application WO/2011/138909
Kind Code:
A1
Abstract:
Disclosed is an air cleaner of a two-cycle engine provided with an air supply path connected to the middle of a scavenging passage by which a scavenging port provided in a side portion of a cylinder and a crankcase communicate with each other to supply lead air from the air cleaner to the scavenging passage, and an air-fuel mixture supply path for supplying an air-fuel mixture generated by a carburetor to the crankcase. The air cleaner is configured by providing a first air passage that communicates with the air supply path and a second air passage that is connected to the air-fuel mixture supply path side by side, and is provided with a choke valve for opening and closing both the first air passage and the second air passage of the air cleaner. The choke valve comprises a swing shaft center, and a swing-type valve element for opening and closing the inlet openings of the first air passage and the second air passage by swinging around the swing shaft center. The inlet opening of the first air passage or the second air passage, which is closer to the swing shaft center, is flattened along the swing edge of the valve element.
