Definitions

  • the invention relates to a hydromassage jet for the irradiation of water and / or air, in which the nozzle outlet opening is closable, the axial outlet of which is associated with a closure body in the flow direction and the opening of the outlet opening is brought about by the pressure of a flowing medium as a result of the movement of the Breech body in the axial or radial direction or as a result of axial movement of a breech body which is arranged within the nozzle housing and a distributor (swivel jet nozzle or jet deflection plate) placed in front of the nozzle housing and the breech body is designed as an annular or cylindrical piston and has at least one medium supply.
  • closable nozzle orifices it should in particular be ensured that when the supply system is rinsed, no detergent flows from the nozzle orifices into the interior of the water basin and the supply system can thus be circulated.

  • the nozzle mouth is closed by pressure-dependent control of the closure body, whereby hydrostatic forces and / or the force from a spring energy store, pneumatic or hydraulic forces are used to move the closure body into its closed position by overpressure and this also when flushing Keep operation in the closed position.
  • This has the disadvantage that only low detergent pressure can be used.
  • the closing force must be such that on the one hand the flow pressure of the blasting medium opens the closure body against the closing force, on the other hand that the flow pressure of the detergent is less than the closing force and the closure body still reliably closes the nozzle mouth when exposed to detergent pressure.
  • Such fine tuning disadvantageously leads to problems in the long run.
  • the invention is based on the object of improving the nozzle orifice closure of a hydromassage nozzle so that detergent cannot penetrate into the inner basin, that the sealing points are largely exposed to the detergent circulation, that deposits do not occur, that the pressure of the detergent does not arise in the jet direction towards the inner basin the sealing seat of the closure body is directed.

  • the closure body 4 When supplying pressurized flow medium through the flow channel 9, the closure body is lifted out of its radial sealing seat and moved into its position opening the nozzle mouth (illustration in the right half). When the medium pressure decreases, the closure body is moved into the closed position by hydrostatic forces or supported by the force of an energy storage device 16.
  • a flexible sealant in the form of a membrane, sealing plate, in the form of a plug or with a concave shape.
  • a bead-like or bellows-like configuration of the essentially cap-shaped closure body is advantageous, which straddles the nozzle mouth and deflects the medium radiation from the center to the radially outside and forms radially one or more medium radiation openings with the jet direction towards the inner basin 10.
  • the closure body is preferably held by a cover 2 on which it adjoins with its side facing the inner basin and between which a spring force accumulator 16 can preferably also be mounted.
