摘要： A hand-held power tool has a tool member and a motor drivingly connected to the tool member, wherein the motor is arranged in a motor housing. A battery for driving the tool member is provided. A guide shaft has arranged on its first end the battery and on its second end the motor housing and the tool member. A rotatably power output part arranged on the motor housing is drivingly connected to the motor. The power output part supports the tool member. Cooling air is sucked through the guide shaft into the motor housing. Between the power output part and the motor housing an annular air exit gap is formed through which the cooling air exits the motor housing. At least one guide vane that projects into the annular air exit gap is provided.

摘要： An exchangeable battery pack for an electric device has a housing with a first end face and a second end face opposite the first end face, wherein the first end is open. A housing cover closes off the first end face. Battery cells are disposed in the housing. Cell connectors electrically connect the cells with one another. An external electrical connector is disposed on the second end face. All of the battery cells are connected to the external electrical connector. The battery cells are charged and discharged through the external electrical connector. A cell holder secures several of the battery cells. An inner positional securing element is provided on an inner side of a sidewall of the housing and the cell holder interacts with the positional securing element.

摘要： An electric power tool has a device housing with a rear grip extending in the longitudinal direction of the device housing. The device housing has first opposed housing sides and second opposed housing sides. An electric drive motor and its electronic control are arranged in the device housing. A battery pack compartment arranged in the device housing receives a battery pack that has a parallelepipedal shape and extends in a direction of a height axis, width axis and depth axis. The battery pack is arranged such that the width axis and the height axis extend transversely to the longitudinal axis of the device housing. The battery pack has narrow sides extending approximately parallel and at a minimal spacing relative to the first opposed housing sides, respectively. The battery pack has opposed end faces neighboring the second housing sides, respectively.

摘要： A method for operating an internal combustion engine having a fuel system which feeds fuel at a given pressure to a metering valve provides that a controller defines the opening time and the closing time of the metering valve and correspondingly actuates the metering valve so that the metering valve opens and closes at the defined times. In order to permit precise metering of fuel even in high-speed internal combustion engines there is provision for the controller to define at least one of the times for the opening or closing of the metering valve while taking into account the counterpressure actually prevailing at the outlet opening of the metering valve.
