    摘要： 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.

    摘要： A combustible mixture of air and minute fuel droplets is produced for supply to the cylinders of an internal combustion engine. This mixture is formed by accurately controlling both the atomization of fuel and the mass flow rate of air over substantially the entire operating range of the engine. These controls are accomplished by introducing liquid fuel into a stream of intake air and uniformly distributing the fuel in the air followed by passing the air and fuel mixture through a constricted zone to increase the velocity of the mixture to sonic. The sonic velocity air at the constricted zone divides the fuel into minute droplets that are uniformly entrained throughout the air stream. The area of the constricted zone and the quantity of fuel introduced are adjustably varied in correlation with operating demands imposed upon the engine. Downstream from the constricted sonic zone, the air and fuel mixture is accelerated to supersonic velocity in a supersonic zone without imparting substantial turbulent flow thereto. Thereafter the mixture is decelerated to subsonic velocity in a subsonic zone to produce a shock zone where the fuel droplets entrained in the air are believed to be further subdivided and uniformly distributed throughout the combustible mixture before the mixture is supplied to the engine cylinders. The supersonic and subsonic velocities occur in a gradually increasing cross-sectional area corresponding to that of a conical section having an apex angle in the range of about 6 to 18 degrees.

    摘要： In a carburetor induction throat, a plate carries a bracket with two parallel ears having coaxial circular openings therethrough. A bushing inserted through the circular openings has sectorshaped stops at one end for engagement with the plate to prevent rotation of the bushing and for engagement with an ear to prevent withdrawal of the bushing in one direction. The bushing further includes one or more deformable projections for engagement with an ear to prevent withdrawal of the bushing in the other direction and one or more deformable fingers at the other end tapering inward to facilitate bushing insertion. A link member includes a pin for insertion in the bushing having a circumferential groove at its free end to directly engage or hold a clip to engage the deformable fingers at the other end of the bushing in order to prevent withdrawal of the pin from the bushing.

    摘要： An internal combustion engine has a supply channel supplying combustion air. A throttle element is arranged in the supply channel and the position of the throttle element is adjustable by an operator-controlled element. The engine has a starter device which has an operating position and a starting position. In the starting position, the starter device opens up a defined flow cross section in the supply channel. The starter device locks in the starting position. The locking is released by actuation of the operator-controlled element. To achieve good starting performance of the engine, the engine has an intermediate stop which, upon the first actuation of the operator-controlled element after the release of the locking, is active and prevents the throttle element from opening fully, and which, during the subsequent closing movement of the throttle element, is deactivated such that the throttle element can be opened fully.

    摘要： In order to provide a carburettor unit for motorized equipment, in particular hand-operated motorized equipment such as a chain saw, a trimmer, a lawn-cutting appliance, a foliage clearing appliance or suchlike, having a housing , in which a throttle valve and a choke valve are held so as to be movable respectively between a closed position and an open position, which overcomes the disadvantages of the prior art and in which an incorrect position between the throttle valve and the choke valve is avoided, it is proposed that a locking element is provided, which is adjustable through the movement of the throttle valve and cooperates with the choke valve such that a movement of the choke valve into the closed position is locked when the motorized equipment is set in operation.
