The present invention relates to a device for cleaning a pump chamber of a vacuum pump, comprising a feed element that can be coupled to the pump chamber for conducting a flushing agent into the pump chamber, and to a method for cleaning a pump chamber of a vacuum pump, wherein flushing agent is pumped into the pump chamber by a feed element coupled to the pump chamber. The aim of the invention is to provide a device and a method of the type in question, with improved cleaning action. The aim is achieved by a device in that the feed element comprises a plurality of air inlet openings on different sides of the feed element, a flushing agent nozzle is disposed in the feed element, and at least one flow cross-section reduction is provided in the feed element. The aim of the invention is further achieved by a method of the type in question, wherein air is pumped into the feed element through a plurality of air inlet openings of the feed element, the flushing agent is conducted through a flushing agent nozzle, whereby a flushing agent-air mixture is generated, and a volume flow of the flushing agent-air mixture is limited by a flow cross-section reduction in the feed element. |
