The invention relates to a diaphragm pump having a delivery space, which encloses a working volume, at least one deflectable diaphragm, which can be moved into a suction position and a pump position, an inlet valve arranged on a suction side of the diaphragm pump and an outlet valve arranged on the pressure side of the diaphragm pump. In order to make it possible to deliver fine-grain powder, for example, non-flowable powders having particle sizes of 0.01 &#x3bc;m to 100 &#x3bc;m, using a diaphragm pump, it is proposed that a gas feed for introducing a gas into the delivery space be arranged at the delivery space. In addition, the invention relates to a method for delivering fine-grain powder.

Diaphragm pump and method for delivering fine-grain powder with the aid of a diaphragm pump

The invention relates to a device and method for generating a barrier discharge in a gas flow, comprising a reactor chamber permeable by the gas from an inflow side to an outflow side, a first electrode, a dielectric that shields the reactor chamber against the first electrode, and a second electrode, wherein the second and the first electrode can be switched to connect to a voltage source. To briefly expose a greater portion, preferably all, of the gas flow through the reactor chamber to a plasma, at least two discharge elements associated with the first electrode and made of electrically conductive material protrude at least partially into the reactor chamber and are electrically insulated from each other and the first and second electrodes, and the second electrode is disposed relative to the discharge elements such that discharges occur between the discharge elements and the second electrode in the reactor chamber.
