Patent number: 7538503Abstract: A hand-held power tool has an electric drive motor having a drive shaft and a tool connected to the drive shaft and rotatably driven by the drive shaft. The drive motor has a control device that has correlated therewith at least a first operating curve and a second operating curve. The control device operates the electric drive motor in idle according to the first operating curve and operates the electric drive motor under load according to the second operating curve. The first operating curve covers the low power range at low speed and the second operating curve covers a large power range at high speed.Type: GrantFiled: April 17, 2007Date of Patent: May 26, 2009Assignee: Andreas Stihl AG & Co.

Patent number: 7438064Abstract: A mixture-lubricated internal combustion engine has a cylinder (2) in which a combustion chamber (3) is formed. The combustion chamber (3) is delimited by a piston (5) mounted to move back and forth. The piston (5) drives a crankshaft (7) rotatably journalled in a crankcase (4). The engine has an inlet channel (9) which supplies fuel and combustion air into the combustion chamber (3) as well as an exhaust outlet (13) from which exhaust gases flow from the combustion chamber. The intake inlet (11) and the exhaust outlet (13) are valve controlled. A flow connection is present between the crankcase (4) and the inlet channel (9). A good idle stability and a good idle acoustic of the engine are achieved in that at least one control valve (23, 33, 43, 63) is mounted in the flow connection.Type: GrantFiled: August 17, 2006Date of Patent: October 21, 2008Assignee: Andreas Stihl AG & Co.

Patent number: 7406771Abstract: A protective shield (2) is provided for a free-cutting tool (1). The free-cutting tool has a cutterhead (4) rotatable about a rotational axis (3) and carries a cutting filament (5). For a rotating cutterhead (4), the cutting filament (5) rotates in a rotational direction (10), aligns itself approximately radially to the rotational axis (3) and defines a cutting circle (6) having a constructively pregiven nominal radius (R). The cutting radius (6) is at least partially covered by the protective shield (2). A cut-to-length knife (7) having a cutting edge (8) for cutting the cutting filament (5) to length is mounted on the protective shield (2) in the peripheral region thereof. The cut-to-length knife (7) is mounted on the protective shield (2) to be moveable back and forth between a cutting position (11) and a rest position (12).Type: GrantFiled: July 17, 2006Date of Patent: August 5, 2008Assignee: Andreas Stihl AG & Co.

Publication number: 20080016705Abstract: A portable handheld work apparatus has a motor housing (2) wherein a drive motor (18) is mounted. The drive motor (18) drives a work tool. The work tool is operatively connected via a drive shaft (8) to the drive motor (18). A coupling device (65, 66, 67) is mounted in the operative connection between the drive shaft (8) and the work tool in order to avoid a transmission of vibrations of the work tool to the drive shaft (8). The coupling device (65, 66, 67) permits a limited movement of the work tool relative to the drive shaft (8).Type: ApplicationFiled: July 17, 2007Publication date: January 24, 2008Inventors: Kai-Ulrich Machens, Philipp Neumann, Thomas Hilt, Gunter Mayer, Adalbert Vielberth
