A snap closure is provided for the detachable securement of a housing cover on a housing of a manually-guided implement, especially to secure an air filter cover that covers an air filter of an internal combustion engine for driving a tool of the implement. At least one snap hook is provided on one of the components that are to be secured together, namely the cover and the housing. The snap hook is provided on an end of an elastically deflectable leg that is disposed on the one component. The snap hook is tapered in the manner of a detent and when the cover is mounted on the housing the snap hook, accompanied by an elastic return force, is engagable in an undercut provided on the other component. The snap hook is deflectable in or parallel to a surface plane on the one component that carries the snap hook.

Snap closure

A hand-held vacuum/blower device has a housing with an interior and a drive motor arranged in the interior. The drive motor has a drive shaft. A blower spiral is connected to the housing. The blower spiral has a first and a second radial end faces and each one of the radial end faces has at least one air inlet opening. A blower wheel is arranged in the blower spiral and coupled to the drive shaft. A venting wheel is coupled to the drive shaft for conveying cooling air from the exterior of the housing to the drive motor in the interior of the housing. The blower wheel has a hub and a wall connected to the hub and extending to the periphery of the blower wheel. The wall has a first end face facing the first radial end face and a second end face facing the second radial end face. The blower wheel includes first and second vanes wherein the first vanes are connected to the first end face of the wall and the second vanes are connected to the second end face of the wall. The first radial end face is part of the housing and the air inlet opening of the first radial end face connects the interior of the housing to the suction area of the blower wheel.

Motor cooling means for a vacuum/blower device

The invention relates to a portable handheld blower/vacuum apparatus having a housing and a blower scroll formed in the housing. An impeller is provided in the blower scroll. Air is supplied to the blower scroll via an air inlet and air is directed away from the blower scroll via an air outlet. An air-conducting connecting tube is mounted on the air outlet via a housing-fixed connecting stub. A bayonet connection is provided in the overlap region between the connecting tube and the connecting stub. The bayonet connection includes a guide path lying in the overlap region. The guide path includes an axial segment and a peripheral segment connected thereto in which a radial cam of the other part engages. The cam is secured form tight by a latch connection in the peripheral segment of the guide path to ensure a reliable, mechanically loadable attachment of the connecting tube in the connecting stub.

Portable handheld blower/vacuum apparatus

A hand-held vacuum/blower device has a housing and a motor arranged in the housing. The housing includes a blower spiral. A blower wheel is arranged in the blower spiral. The housing has a top side and a bottom side. A first grip is connected to the top side, and a second grip is connected to the bottom side. A support element is provided at the bottom side and has a first support surface for supporting the vacuum/blower device in a rest position. The second grip has a second support surface extending at least over a portion of its length at the same level as the first support surface.

Vacuum blower/device having a second grip and a support at a lower area

The invention relates to a cutoff machine having an internal combustion engine arranged for driving a work tool. The engine is held in a housing including a supporting component. Located in the housing is a fuel tank, from which the internal combustion engine is supplied with fuel. The fuel tank itself is connected via a venting tube to an equalizing vessel, which communicates with the atmosphere via a valve system. In order to connect the fuel tank to the equalizing vessel in an easily produced and assembled manner and in order to ensure safe venting of the fuel tank, a hollow body is provided in the supporting component. The hollow body is partitioned by a partition wall into two chambers, the one chamber forming the fuel tank and the other chamber forming the equalizing vessel. Both chambers are connected to each other via a one-piece venting component in which a venting line is formed.
