Motorised chain saw with IC engine

摘要

The handle of the saw contains a movable fuel lever coupled to the throttle valve by a fuel rod linkage (15') which comprises a first and second thrust rod (19',20') coupled by a first lever (21'). A second lever (24') engages on the first lever and has a locally fixed rotary point (26'). A compensating element extends away from the housing (10') towards the handle and is in active connection with the second lever. The first and second levers can be stretched levers each with three bearing points (22',23',25';25',26',30') coupled together at their ends by a swivel bearing (25'). The compensating element is preferably a coupling rod (28') attached to the end of the second lever remote from the swivel bearing and with the other end set on a bearing point (29'). The relative movement between housing and handle is converted into compensating movement of second lever.
