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.

Function control for an electrohydrodynamic atomizer

A fault-rectification method for an eccentric screw pump of a conveying apparatus for conveying viscous construction materials, comprising the steps of monitoring a start of a conveying operation of the eccentric screw pump by way of a characteristic-variable-monitoring program of a control device of the conveying apparatus, wherein a working-free program is executed by the control device of the eccentric screw pump if, for one or more characteristic variables. The characteristic-variable-monitoring program acquires characteristic-variable values which are stored, alone or in combination with one another, as fault values that indicate jamming of a rotor/stator unit of the eccentric screw pump, and wherein otherwise a conveying operation is begun. The eccentric screw pump is operated in the working-free program in such a way that an electric motor of a drive unit of the conveying apparatus is multiply alternately switched on and switched off.

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 spraying paint with a gun housing () provided with a handle () with a union nut () screwed onto it that holds an air cap () provided with offset outlet openings () for compressed air, the union nut () is positively connected to the air cap () in a circumferential direction. This embodiment makes it possible for the spray jet to be set in a brief time and without difficulties without having to put up with getting dirty. It is merely necessary to turn the union nut () accordingly in order to control the air supply to the outlet openings () of the air cap () and therefore to influence the formation of the spray jet.

A spray gun for spraying paints and similar viscous media that can be propelled pneumatically, comprising a gun housing for accommodating components of the spray gun that effect propulsion, mixture and/or metering, a handle projecting from the gun housing, and a reservoir tank removably attached to the gun housing for holding the medium to be processed, with the housing of the spray gun provided with an air guidance duct through which the compressed air responsible for atomization flows to an atomizer nozzle, wherein surfaces of the air guidance duct and/or atomizer nozzle, and/or an air cap, which come into contact with the stream of compressed air, or are wetted, are provided wholly or in part with a structured surface in the form of indentations and/or protrusions worked into the surfaces.

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.
