Definitions
- the ejector pumps are made more compact and can be produced with less injection molding compound.
- the device according to the invention has a plurality of suction jet pumps 1 each having a drive nozzle 2 and a mixing channel 3.
- the suction jet pumps 1 are provided for example in a common housing 1.1, which is made for example of plastic and by injection molding.
- two suction jet pumps 1 are formed on the housing 1.1.
- the mixing channels 3 each have a circular flow cross-section and are separated from one another, for example, by means of a dividing wall 32.
- the separation of the mixing channels 3 ensures that the propulsion jets can not influence each other.
- the partition wall 32 runs, for example, from the end facing the suction chamber 6 in the direction of the channel axes 30 to the end of the mixing channels 3 facing the diffuser 25 and can project into both the suction chamber 6 and the diffuser 25 on both sides. Since the dividing wall 32 ends in the region of the outlet openings 23 of the mixing channels, the mixing channels 3 open into a single channel forming the diffuser 25.
- the Partition wall 32 is designed as a common mixing channel wall for each two adjacent mixing channels 3 and designed, for example, arched.
