Abstract
Jet regulator and aerator for attachment to a faucet contains a circular perforated plate for producing individual jets, and a coaxial sleeve downstream. The sleeve supports--deflection slopes which are inclined at an angle to the flow direction. The deflection slopes may be in the form of conical-pointed pins aimed at the plate. The pins are mounted on a tiered-wedding-cake shaped wall. An axial cone in the sleeve may also comprise a deflection slope. Additional obstacles consist of pins and/or ribs located at intervals from each other.
Claims20
A stream softener and aerator adapted to be installed in a water supply fitting comprising
- a. a perforated circular plate having flow holes arranged in concentric circles about its axis;
- b. a sleeve coaxial with the plate and having the plate secured to its upstream end, the sleeve having supported concentrically within it a first circular ring wall having spaced annular surfaces perpendicular to the axis and being of decreasing outer diameter in the upstream direction, the wall having formed thereon a plurality of pins having their distal ends aimed toward the plate and deflection slopes on said distal ends at least some of the pins being aligned with flow holes respectively in the plate so that jets from the holes will engage the deflection slopes and be deflected outward, and means in the sleeve for introducing air into the space between the plate and the deflection slopes.
A flow controller and aerator for attachment to a faucet comprising a tubular sleeve adapted to be disposed axially of the flow, a perforated plate adapted to be disposed on the upstream side of the sleeve transverse to the flow, the plate being formed with a number of holes, a first circular ring wall concentrically supported in the sleeve, deflection slopes supported on the wall in the form of pins having their distal ends conical and directed toward the plate to deflect jets emanating from the holes in a direction outward with respect to the centerline of the sleeve, and means for drawing air into the space between the holes and the deflection slopes.
