A spray head is provided for a blower tube of a spray apparatus. The blower tube is adapted to conduct a blower air flow to the spray head () in a flow direction (). The spray head includes a supply pipe () for a medium to be sprayed such as a liquid. The spray head also includes an inlet opening for receiving the blower air flow () and an outlet opening through which the blower air flow is discharged from the spray head enriched with the medium. The supply pipe () has an outer feed connection for the medium and a discharge opening () in the interior of the spray head for admixing the medium into the blower air flow (). The discharge opening () defines a plane aligned in the flow direction () and an impediment is disposed at the edge of the discharge opening lying upstream with respect to the flow direction (). The impediment disturbs the blower air flow entering the spray head through the inlet opening before it flows over the discharge opening. In this way, noise excitation is avoided while obtaining a good atomization of the medium.

A protective shield for a trimmer having a cutting head that is rotatable about an axis of rotation and supports a cutting thread that rotates about an axis of rotation with the cutting head and determines a cutting circle, covers at least partially the cutting circle. The protective cover has a base member and a cutting-to-length blade arranged on the base member so as to be positioned circumferentially relative to a cutting circle of the rotating cutting thread. The cutting-to-length blade has a cutting edge that, relative to the axis of rotation of the rotating cutting thread, is arranged in an axially displaced position displaced in an axial direction relative to the cutting circle. A device for axially deflecting the rotating cutting thread out of the cutting circle to the cutting edge is provided.

A backpack suction/blower apparatus has a blower unit () which includes a drive motor (), a blower (), which is driven by the drive motor (), and a blower tube () extending from the blower (). A back carrier frame () is provided on which the blower unit () is attached at a spacing while forming an intake gap (). The intake gap () is filled with a foam attenuating element () in the lateral direction () referred to the usual working position.

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.

A manually guided brushcutter or other trimmer having a guide tube that accommodates a transmission shaft, with a drive motor that drives the transmission shaft and a housing that secures the drive motor to the guide tube. The housing is embodied as a closed engine housing that surrounds the drive motor. The drive motor and the closed engine housing are interconnected at two spaced-apart securement points.
