Title:
CONDUCTING AND COUPLING MECHANISM BETWEEN ANGLED VALVE STEMS
Document Type and Number:
WIPO Patent Application WO/2005/047672
Kind Code:
A1
Abstract:
A conducting and coupling mechanism between angled valve stems, wherein a cam plate (28) and a lever (23) are fitted to a lead air control valve stem (27) and an air-fuel mixture throttle valve stem (22) disposed at an angle. A spring (46) energizing a lead air control valve in the valve closing direction is disposed on the lead air control valve stem (27) and a spring (45) energizing an air-fuel mixture throttle valve in the valve closing direction is disposed on the air-fuel mixture throttle valve stem (22). The length of a contact (24) fitted to the lever (23) is extended parallel with the axis of the air-fuel mixture throttle valve stem (22) so that the length of the contact (24) becomes such that the contact (24) always comes into contact with a cam face formed on the cam plate (28). The lead air control valve stem and the carburetor air-fuel mixture throttle valve stem disposed at the angle are conducted and coupled to each other, and a stratified scavenging two-cycle engine can be reduced in size without sacrificing a space for the stratified scavenging two-cycle engine in the height direction.
