Abstract
A rotary-type carburetor (1) according to the present invention includes a body (4) having a bore (2) with a circular cross section, and a valve element (6) to be contained in the bore (2). The valve element (6) rotates between a closed position where the valve passage (16) is blocked from communicating with the body passages (10a, 10b), and a fully-opened position where the valve passage (16) and the body passages (10a, 10b) are aligned. When the valve element (6) is located in an idle position, an air flowing through the body passages (10a, 10b) and the valve passage (16) is prevented from being flown into the bore end part (12). When the valve element (6) is located in a fully-opened position, a portion of the air flowing from an upstream part (10a) of the body passage is bypassed into the upstream communication part (32).
