  • Patent number: 8997959
    Abstract: Clutch arrangement for a motor vehicle gearbox. The clutch arrangement has a housing and a clutch. The clutch is arranged in the housing and is arranged concentrically with a shaft, which extends in a longitudinal axis. The shaft is supported on the housing by means of a first shaft bearing adjacent to the clutch and by means of a second shaft bearing spaced at an axial distance from the clutch. The clutch arrangement has an actuator arrangement for actuating the clutch. The actuator arrangement is designed to exert an actuating force on the clutch in a first longitudinal direction. The actuator arrangement here being axially braced on the housing and a force flux being introduced into the shaft as a result of the actuating force. The first shaft bearing is arranged so that the force flux introduced into the shaft can be axially braced on the housing by way of the first shaft bearing.

  • Patent number: 7373921
    Abstract: A manually guided implement having a motor unit and a tool unit driven by the motor unit. The motor unit includes an internal combustion engine having a carburetor, and a butterfly valve. A throttle acts upon the butterfly valve via a transfer mechanism. A speed regulator is provided for the internal combustion engine. The transfer mechanism is divided into two transfer portions. The speed regulator is a mechanical speed regulator and is disposed between two transfer portions such that the throttle, via the first transfer portion associated therewith, as well as the speed regulator together act upon the second transfer portion, which is associated with the butterfly valve, whereby as its speed increases, the speed regulator effects a closing of the butterfly valve.
