摘要： A power saw chain comprises a central row of driving links and outer rows of cutting links and side links with each cutting link being laterally aligned with a side link and adjacent a side link longitudinally of the chain. The undersurfaces of said adjacent side links are designed to run on a guide plate surface while the undersurfaces of the cutting links and the laterally aligned side links have clearance from said surface to reduce the vibration effect of the chain.

摘要： The present invention relates to a carburetor of an internal combustion engine having a manually activated start position. The carburetor comprises at least a choke valve and a throttle valve both located in the carburetor's main air passage which are able to move between an open and a closed position, each valve having at least one respective lever that cooperates during the manual activation to give at least one start position of the choke and throttle valves. The carburetor further usually comprises at least one thermally responsive member arranged to affect the start position. Further a handle is arranged to provide a two stage draw—lift motion to attain the start position.

摘要： An automatic valve for reducing compression in order to facilitate starting of a two-stroke internal combustion engine includes a movable valve (25) adapted to control a gas flow through an opening (16) provided in a wall of the combustion chamber of the engine. A spring (27) is adapted to move the movable valve (25) to an open position, and a drive actuated by an underpressure is adapted to move the movable valve (25) to a closed position against the action of the spring (27). The driver includes a cylinder (18), a piston (19) movable in the cylinder (18) and connected to the movable valve (25), and a conduit (22) connecting the cylinder (18) to a source of underpressure. A one-way valve (23) is provided in the conduit (22) for allowing an air flow in a direction a way from the (18) only, and a leak passage (30) is adapted to allow a small flow of air into the (18) for facilitating the opening of the movable valve (25) when operation of the engine has been stopped.
