Abstract
The invention relates to a water jet aerator which, in place of conventional metal screens, has at least two separate staircase-like obstacles, which project laterally into the paths of the individual jets and split up the jets, and mix them with air. Several such obstacles are arranged in the immediate proximity of one another, successively in the direction of flow, so that a cohesive, well-ventilated jet is obtained. The configuration of the jet cross-section can vary as a function of the arrangement of the facing walls defining the flow path in the area of the obstacles.
Claims31
A water jet ventilator for sanitary fittings and the like, comprising:
- at least one device for producing a plurality of individual water jets along a direction of flow;
- a housing defining at least one chamber arranged downstream of said device for producing individual jets, the housing having an opening for air access to the chambers;
- at least one device for splitting and mixing the individual jets with air, having at least two separate devices for splitting up the individual jets, each having two cooperating walls defining passages which catch the individual jets, at least one of the two cooperating walls having lateral obstacles defining a staircase structure projecting into a path of the individual jets, at least one of said separate devices for splitting the individual jets having two facing cooperating walls, the cooperating walls continuing downstream of the devices and defining unobstructed channels, the cooperating walls of the separate devices having obstacles directed towards one another, the separate devices being displaced from one another in the direction of flow, and the separate devices for splitting the individual jets being so closely juxtaposed that the ventilated jets flow out as a joint ventilated jet.
