Abstract
A transmissible connecting mechanism having a cam plate and a lever are attached respectively to a lead air control valve shaft and an air-fuel mixture throttle valve shaft which are arranged so as to form an angle. A length of a contact element provided in the lever is extended in parallel to an axis of the air-fuel mixture throttle valve shaft, and the length of the contact element is such that the contact element and a cam surface formed in a cam plate are always brought into contact with each other. The lead air control valve shaft and the air-fuel mixture throttle valve shaft of the carburetor are connected in a transmissible manner, and it is possible to make a stratified scavenging two-cycle engine compact.
Claims4
A transmissible connecting mechanism between valve shafts forming an angle, the transmissible connecting mechanism interlocking and driving the both valve shafts, which are respectively a lead air control valve shaft and an air-fuel mixture throttle valve shaft of a carburetor in a stratified scavenging two-cycle engine, wherein one of the valve shafts is a drive shaft and the other valve shaft is a driven shaft, wherein
- the drive shaft and the driven shaft are disposed in a configuration to form an angle between the drive shaft and the driven shaft,
- the transmissible connecting mechanism is arranged so as to be integrally rotatable with the drive shaft and the driven shaft respectively, and is provided with a pair of first cam member and a second cam member which are transmitted to each other in a contact manner, and
- a part of a contact surface of the first cam member and a part of a contact surface of the second cam member are always maintained in a contact state at a time of a contact transmission of the first cam member and the second cam member.
