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.

Battery pack for a hand-guided power tool

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.

Electric power tool with battery pack

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.

Hand-held power tool

A hand-held electric device has a device housing with a battery pack compartment. A battery pack is disposed in the battery pack compartment. The battery pack compartment has guide elements extending in the insertion direction of the battery pack. The battery pack has a battery pack housing and guide sections provided on the battery pack housing that interact with the guide elements. The battery pack has an electric connector head disposed on the battery pack housing. The battery pack compartment has contact elements. In a predetermined insertion position of the battery pack in the battery pack compartment the contact elements electrically contact the connector head. A contact plate is floatingly supported in the battery pack compartment and the contact elements are disposed on the contact plate.

Portable hand-guided electric device with battery pack

A portable spraying device has an internal combustion engine and a blower driven by the internal combustion engine. A blower tube is connected to the blower and conveys a blowing air stream generated in the blower. A spraying agent reservoir is provided and a spraying agent line is connect to the reservoir and conveys a spraying agent stream from the reservoir into the blowing air stream. A control valve is arranged in the spraying agent line. A throttle control acts on the internal combustion engine for controlling an engine output. A stop switch acts on the internal combustion engine for interrupting ignition. An actuating element acts on the control valve for actuating the control valve to control the spraying agent stream. A handle with a handle head is provided and the throttle control, the stop switch, and the actuating element are arranged in the handle head.

Portable spraying device

A portable spray apparatus () is provided to selectively discharge liquid spray medium and solid dust medium with a blower airflow () generated by a blower (). An adaptor () is provided which has at least a channel section () of a liquids channel () for the liquid spray medium and a channel section () of a solids channel () for the solid dust medium. The adaptor () is releasably connected to a supply vessel (). The liquids channel () and the solids channel () open into the blower airflow (). Various built-in positions of the supply vessel () and of the adaptor () are freely selectable relative to each other and to the blower unit () by the operator. In one built-in position, the liquids channel () is connected via its channel section () to an interior space () of the supply vessel () and, in another built-in position, the solids channel () is connected to this interior space () via the channel section () thereof.

Portable spray apparatus

A portable handheld apparatus such as a brushcutter, blower or the like has a drive motor and a throttle lever (). The throttle lever () is pivotally journalled about a rotational axis (). The throttle lever () acts on an actuating device for controlling the drive motor. In order to make possible a simple adjustment of the actuating device, it is provided that the throttle lever () has an operator-controlled lever () and an actuating lever (). The operator-controlled lever () can be actuated by the operator. The actuating lever () acts on the actuating device. The relative position of the actuating lever () relative to the operator-controlled lever () is adjustable.

Portable handheld work apparatus

A portable handheld work apparatus such as a blower or brushcutter or the like has an actuating device for controlling the drive motor of the work apparatus. A throttle lever () is provided which acts on the actuating device. A fixing device () is provided for the throttle lever (). In order to obtain a simple, reliable fixing of the throttle lever (), the fixing device () includes blocking elements which fix the throttle lever () in a latching position () of the fixing device () in at least one pregiven position and which enable the throttle lever () in the operation-disabled position () of the fixing device ().
