A spraying device includes a tool body, a handle, and an energy store. The tool body is carried by way of the handle and one end of the handle, on the opposite side to the tool body, includes a coupling for mechanically and electrically coupling an energy store. A cage is connected to the coupling incorporated in a top of the cage. The cage includes two webs curved in a U shape arranged opposite one another and are each connected to the top of the cage. In a coupled state, the energy store is received in an interior space of the cage in such a way that the two webs each protrude downward beyond a housing of the coupled energy store and into the space. The energy store is assigned a lower opening, a left-hand opening, a right-hand opening, a front opening and a rear opening of the cage.

Spraying device and portable power tool system

A method for the function control of an electrohydrodynamic atomizer, wherein an electrohydrodynamically atomized fluid, originating from the atomizer, is applied to a body, e.g. a person, in order to coat this body at least in certain areas, wherein the atomizer-comprises a fluid tank for storing the fluid and at least one high voltage source for making available a high voltage and at least one pump unit for transporting the fluid, wherein the fluid is delivered to a nozzle arrangement of the atomizer by means of the pump unit, and wherein the fluid is atomized electrohydrodynamically at the nozzle arrangement by means of the effect of the high voltage from the high voltage source, wherein a voltage and/or a current at the high voltage source is evaluated in order to acquire a working point of the high voltage source via a current/voltage characteristic curve.

Spray gun for paint

Sprayer

A paint spraying system is proposed with a paint spraying device with a paint spray gun with a fan for dispensing paint via a spray head, which paint spraying device is connected via a paint line to a base station with a connector to a paint reservoir. In order to achieve a low and uniform paint pressure which is required in the paint spray gun, the paint spray gun is equipped with a separate pressure reducing device and the base station is equipped with a pressure monitor, which pressure reducing device and pressure monitor perform a pressure regulation of the paint pressure in the system.

Paint application system

The invention relates to a spray head having a slot-shaped central air outlet opening and preferably a slot-shaped paint nozzle for forming a flat jet of paint in an air-propelled application process.

Paint spray gun

In a spray gun for spraying paint and similar media, there is provided a gun housing and a reservoir tank removably attached to the gun housing for holding the medium to be sprayed. The reservoir tank is configured as a commercially available storage container, for example in the form of a paint can, and is directly attached via an adapter to a projection connected to the gun housing. Thus, commercially available storage containers, differing considerably in their dimensions, can be directly fitted onto the gun housing in a short time and by a reliable method. Viscosity settings and transferring of media to be processed from one container to another are therefore not necessary, and the medium can be matched to the particular working implement and application.

Spray gun

In a spray gun () for atomizing fluids, that can be actuated using a lever () mounted in a pivoting arrangement on a sleeve () which accommodates an atomizer nozzle () and in which the air flow can be generated by an air turbine () that is assigned to the spray gun (), the air turbine () and its electric drive motor () are arranged substantially coaxially to the sleeve () on the opposite side of a handle () and the air flow is supplied from the air turbine () in a substantially straight line through the sleeve () of the atomizer nozzle (). The air turbine () is provided with a muffler (). Loud operating noise of the air turbine () 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 () are arranged in such a way that no more than slight tilting torques are generated, permitting work over long periods without leading to fatigue.

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). Also, a switching device (32) is connected to the drive motor (12) and is integrated into the electric circuit (22) so that the switching device (32) is arranged in a branch line (31) bypassing the second contact element (26) and by which the second contact element (26) can be bypassed in an open operating position caused by the depth stop (16) by actuation of the first contact element (25) for reversal of the direction of rotation of the drive motor (12), which makes it possible to switch the drive motor (12) from clockwise to counter-clockwise rotation or the reverse without the necessity of mechanical elements and without the necessity of any manual manipulation of adjustment elements.
