摘要:
A percussion tool has a cooling air channel for guiding a cooling air flow from a cooling air fan to an outside wall of a cylinder of an internal combustion engine. The cooling air channel is tapered to the extent that partial cooling air flows guided between the respective cooling fins are branched off the main cooling air flow. In such a way, the flow rate of the cooling air flow in the cooling air channel remains substantially constant, resulting in optimized engine cooling. The cooling air channel may be divided into two cooling air channels downstream of the cylinder. One of the cooling air channels guides cooling air to an exhaust gas system of the internal combustion engine, while the other cooling air channel guides cooling air to an outside wall of the guide housing of a hammer mechanism.

An implement having a drive, a drive element that may be driven by the drive and that is disposed in an axially moveable manner and is coupled to the drive element, and an overrunning clutch disposed in the drive or in a torque flux between the drive and the drive piston. If the drive has a movement that is slower than that of the drive element, the overrunning clutch is in an idle state, in which the clutch interrupts the torque flux between the drive and the drive element, thus decoupling the movement of the drive element from the drive torque of the drive. In this manner, the drive element may move more rapidly, for example during the return movement thereof, than would correspond to the movement forced by the drive.

Use of fine-particled biocidal aqueous cationic dispersions of polymers as biocidal treatment agents for substrates at risk from microbes, preferably for fungicidal, bactericidal and/or algicidal treatments. The dispersions of polymers used are biocidal cationic dispersions of polymers which can be obtained from suitable monomers by emulsion polymerization and which contain biocidal cationically surfactant quaternary organic ammonium compounds, preferably tetra-substituted ammonium compounds of the formula (I) and/or alkyl- or alkenylpyridinium compounds of the formula (II), in particular in an amount of 0.1 to 20% by weight, based on the disperse polymer. The average particle diameter of the polymer particles in the biocidal cationic dispersions of polymers is preferably 0.02 to 0.5 .mu.m at a cationic activity of 1.5 to 600 .mu.mol per g of solid, measured at pH 7, and the solids content of the dispersions is preferably 3 to 40% by weight. The biocidal cationic dispersions are preferably used as treatment agents for the preservation of wood, for emulsion paint films and for polymer plasters or synthetic resin plasters, it being possible for the biocidal treatments which can be achieved to display surprising long-term biological actions.

A piece of equipment which has a ground contact device for working on a ground region located below the ground contact device in the working position of the piece of equipment, a driving device which can be operated by an electric motor in order to produce a working movement of the ground contact device, an electrical energy accumulator, enclosed by a housing, for supplying the electric motor with electrical energy, and a covering device for covering the housing and thus the energy accumulator, which covering device is arranged above the energy accumulator in the working position. The piece of equipment may for example be a tamper, a vibration plate, a roller, or a breaker.
摘要:
An implement comprises an internal combustion engine having a throttle valve. At least one handle, the inside of which is provided with a gas lever likewise in a pivotal manner, is attached to a housing surrounding the internal combustion engine. The minimum distance between the gas lever and the handle is defined by a stop. When the operator lifts the implement by the handle, the position of the gas lever also changes. Even when the gas lever is fully depressed, only a part-load position is achieved at the throttle valve. In this way, effective rotational speed limitation is achieved.
