Definitions

  • the invention relates to a trigger and a method suitable for cleaning the trigger according to the generic terms of the associated claims.
  • a trigger according to the preamble of claim 1 is already known (DE-PS 20 29 607).
  • the functioning of such a trigger requires that the pole faces of the mutually corresponding armature and magnet yoke pole faces are not only ground well to one another, but that these faces and their surroundings are free from impurities in order to keep the required smallest possible magnetic air gap constant.
  • This requirement has so far been met in that the housing, which surrounds the finished trigger to the outside, consists of several parts, the last part to be assembled, usually the housing surrounding the trigger, after intensive cleaning of the trigger in liquid cleaning agents followed by drying and the shutter is closed to the outside. Pre-cleaning of the housing is then also required. With this method, it cannot be ruled out that in the period after cleaning and until the trigger closes, contamination will again occur, whether due to the effects of dust or tampering.
  • the invention is therefore based on the object of strengthening a trigger of the type described above to the extent that cleaning with a liquid cleaning agent is made possible and also to show a method by means of which such a cleaning can be carried out during the import process.
  • This object is achieved according to the invention by the trigger defined by the characterizing features of claim 1 and a method specified by claim 6.
  • the advantages achieved with the invention are that only the housing has to be changed slightly in order to carry out an effective liquid cleaning. Two openings of the same size are sufficient for the entry and exit of the liquid cleaning agent.
  • the trigger is already closed by the housing except for the two openings, so that contamination or damage to the trigger parts is no longer possible.
  • the trigger is actuated not in air but in a suitable liquid medium during the loading process, so that all of the abrasion particles are released into the liquid medium and not into the Pole surfaces can be struck. When the liquid medium moves, these disruptive particles are washed away immediately after they are formed.
  • the trigger is clamped during the cleaning process in a receiving device, which is then immersed in a container filled with the cleaning liquid (claim 7).
  • This recording device can also be designed so that several triggers can be cleaned at the same time.
  • the pump can advantageously be used not only for the flow of the cleaning liquid, but also for pumping out the remaining cleaning liquid (claim 12).
  • Valves in front of and behind the pump ensure that dry gas can be passed into the housing interior when the pump is switched off (claim 13).
  • the dry gas can be liquefied in a condenser after it has flowed through and thus advantageously returned to the cleaning agent circuit.
  • the trigger 1 is closed in a dust-tight manner from the outside by a housing 10 designed as a cap, which is locked with a base plate 10 '.
  • the trigger itself consists of a U-shaped magnetic yoke 2 with an armature 3, which is designed here as a hinged armature.
  • a coil 4 is arranged on one leg of the U-shaped magnetic yoke.
  • Below the magnetic yoke there is a permanent magnet 5 in a recess in the base plate 10 '.
  • a release pin 6, the end of which rests on a section of the armature 3 located between the poles of the magnetic yoke, serves as an actuating member to the outside, for which purpose the housing 10 has a one Guide provided opening.
  • the housing is equipped with an opening 11 for the entry of a cleaning liquid and with an opening 12 for the exit thereof.
  • a receiving device 13 in which the trigger 1 is clamped, is used to carry out the cleaning process of the trigger described under FIGS. 1 and 2.
  • the receiving device is placed with the trigger in a container 14 which is filled with a cleaning liquid 16 up to the liquid level 17 via a storage container 15.
  • a pump 19 presses the cleaning liquid into the inlet opening 11, from where it penetrates into the interior of the housing and flows around the parts of the trigger.
  • the cleaning liquid is returned to the pump through a filter 20 through the outlet opening 12.
  • a plunger 21 is actuated several times with the circulating cleaning liquid by a corresponding drive 22, the plunger acting on the release pin 6 of the release.
  • the plunger can be driven electromagnetically, pneumatically, hydraulically or by motor.
  • the cleaning liquid is lowered to the liquid level 18.
  • the pump 19 then sucks the remaining liquid 16 from the interior of the housing, which then takes place at Switching from two valves 23 and 24 to the flow through the interior of the housing with a dry gas 25.
  • the dry gas can liquefied after flowing through the interior of the housing in a condenser 26 and thus returned to the cleaning agent circuit.
  • the trigger is removed from the receiving device and the bores 11 and 12 are closed.
