Definitions

  • the invention relates to a water nozzle, in particular for dust control, for example on cutting rollers, which essentially consists of a housing which can be screwed into a water supply line and has a collecting bore on the water inlet side and a central bore of small diameter on the water outlet side.
  • a water nozzle which has an insert inside the receiving bore and is pressed into the water inlet side and a spray chamber between the central bore and the insert.
  • the spray chamber is intended to avoid additional swirling of the water and thus the dirt in the area of the nozzle.
  • the spray chamber is said to facilitate cleaning in that the cleaning work can be carried out with a thin wire through the central bore.
  • the invention has now set itself the task of creating a water nozzle, in particular for dust control, for example on scraper rollers or other underground facilities, which avoids the blockages while avoiding the above-mentioned disadvantages and largely guarantees the functionality of the nozzles Manufacturing is easy and inexpensive.
  • the collecting bore is divided into two sections, and that in the section of the receiving bore of the housing and screwed into this, a stepped guide sleeve is arranged with a piston which is stepped several times in the axial direction and can be pretensioned by a spring.
  • the guide sleeve consists of a channel-like feed and a subsequent widening on the water inlet side and the piston arranged in the guide sleeve has a slight widening in the feed and a strong widening within the widening.
  • the water nozzle shown in section in the drawing consists essentially of a housing 1 having an external thread 3, in which a central bore is made.
  • the collecting hole is divided into two sections 2 and 17 with different diameters.
  • a guide sleeve 5 can be screwed into section 2 of the collecting bore by means of a further thread 4.
  • the thread 3 is provided for connection to a water supply line.
  • the guide sleeve 5 has a narrowed channel-like guide 7 on the water inlet side and then an extension 8.
  • the extension 8 goes inside the housing 1 in the overlapped 17.
  • the section 17 as part of the central bore is provided with a step 15 in relation to the extension 8.
  • a multiply graduated piston 6 is arranged within the guide sleeve 5.
  • the piston 6 At its upper end arranged on the water inlet side, the piston 6 has a slight reinforcement 9 and a larger reinforcement 10 within the extension 8.
  • the piston 6 At the lower end of the piston 6 on the water outlet side, the piston 6 has a piston stub 14.
  • the piston 6 can be pretensioned by means of a spiral-shaped spring 13.
  • In the reinforcement 10 there is a horizontal bore 11 and a bore 12 extending vertically through the piston stub 14.
  • the spring 13 is mounted within the section 17 in the step 16, which is designed as an abutment.
  • the upper end of the spring is guided through the piston stub 14.
  • the central bore 18 connects to the section 17 on the water outlet side.
