  • Publication number: 20050269425
    Abstract: In a spray gun (1) for atomizing fluids, that can be actuated using a lever (15) mounted in a pivoting arrangement on a sleeve (11) which accommodates an atomizer nozzle (12) and in which the air flow can be generated by an air turbine (5) that is assigned to the spray gun (1), the air turbine (5) and its electric drive motor (4) are arranged substantially coaxially to the sleeve (11) on the opposite side of a handle (21) and the air flow is supplied from the air turbine (5) in a substantially straight line through the sleeve (11) of the atomizer nozzle (12). The air turbine (5) is provided with a muffler (6). Loud operating noise of the air turbine (5) does not have a disruptive effect and practically no flow noise is generated due to deflections of the air flow. The components of the spray gun (1) are arranged in such a way that no more than slight tilting torques are generated, permitting work over long periods without leading to fatigue.

  • Patent number: 5918685
    Abstract: A hand tool (1) having a drive motor (12), a depth stop (16) by which the drive motor (12) can be automatically switched off when it is in contact with a workpiece (4), and a switching mechanism (21) in an electric circuit (22). The electric circuit (22) includes a switch (24) for switching the drive motor (12) on and off, a first contact element (25) for reversing the polarity of the drive motor (12) and a second contact element (26) for switching off the drive motor (12) by the use of the depth stop (16).
