Vacuum pump

The innovation ahrcngsmittel relates to a vacuum pump or a device for producing a Un.erdruckes in airtight containers, in particular in packaging containers made of plastic for i \ ^T.

Especially in butcher technology these days wix'd to the Airtight packaging of meat worked according to methods in which a high negative pressure in the packaging bags is generated (vacuum packaging). To generate the vacuum required for this purpose, vacuum pumps are known which are very are expensive and complex, which are operated with electricity, and which cause considerable noise in operation as well as subject to relatively high wear and tear over time.

The task of the innovation is to create a device which is simple and cheap to manufacture, which does not require electrical connections, no moving parts possess' uni darit has a very long service life and with the help of which it is possible to achieve a sufficiently high vacuum achieve, which roughly corresponds to that with conventional, complex vacuum pumps.

According to the innovation, it is proposed that in a housing with a water connection a water flow constricting and a swirl-imparting insert body is provided for the water jet. that a funnel-shaped component downstream arranged is *: that the rich when leaving the r Insert body widening V / water jet receives, and that with the housing approximately between the outlet of the housing part Water connection and the upper part of the funnel-shaped ßau- "eiles has an outlet part arranged transversely to the direction of the water jet, from which a connection to the container leads. Purposely is in-: connection to the funnel-shaped Narrowing a widening flow part with a subsequent further narrowing provided in order to achieve the following: of the flowing water jet to generate the Increase vacuum.

The insert body has the shape of a projectile tip on whose original surface there are grooves which run towards the tip at a small angle to the axis. This achieves, in general, a water jet from the water pipe through the / rel sringfö ^ rripren channel between the housing and Γ Insert body pressed through and to it by the oblique ij running grooves irr. Insert body when leaving the emergency ser.des a rotary movement or a twist is given on the insert body. The water jet emerges expanding in a radial direction rr.it this: Twist Ir. the funnel-shaped component
