A clutch device for working vehicles including a pressure member integrally rotatable with a crankshaft of an internal combustion engine of the vehicle, a centrifugal weight supported by the pressure member, the centrifugal weight being centrifugally movable in a higher revolution region than a predetermined number of revolutions of the crankshaft, a clutch outer member driven to be rotated by the pressure member, a plurality of drive friction plates integrally supported by the clutch outer member, the drive friction plates being axially movable, a clutch inner member fixedly provided with a plurality of driven friction plates frictionally engageable with the drive friction plates and having an output portion connected to a working implement of the vehicle, and a member for resiliently biassing the drive friction plates and the driven friction plates in their engagement direction. The clutch device, in which the clutch outer member is arranged to be axially movable, further comprises a restriction member for restricting the axial movement of the clutch outer member, and a control mechanism for controlling to shift the restriction member such that the clutch outer member has an axial position thereof let to be an arbitrary element of a set consisting of, with respect to the drive and driven friction plates, a normal-open position, a frictional-engagement permitting position under effect of the centrifugal movement of the centrifugal weights, and a normal-close position.

Clutch device for working vehicles

A process and apparatus for controlling the decompression of an internal combustion engine for driving compressors, electric generators, and the like, the process including the steps of starting the engine with the decompression control engaged and the engine decompressed, partially activating the control when the engine reaches a first predetermined speed so that, as the speed is increased, the engine operates compressed, when the engine reaches normal operating speed, fully activating the control and, when the engine speed is decreased to a second predetermined speed below said normal operating speed but above said first predetermined speed, the control is reactivated for decompression operation of the engine until the engine stops. The apparatus comprises a decompression weight and subsidiary decompression weight, pivotally mounted for movement by centrifugal force relative to the engine cam shaft and interconnecting means for interconnecting the weights when the engine is started and until the engine reaches a first predetermined speed, releasing the weights, one from the other, above such predetermined speed, and re-engaging the weights after the engine is stopped.
