  • the double plunger has two plungers 2A and 2B, which are at the rear, at the opposite end of the device, connected to each other via a handle 2C with handle opening 2D and define a slot 15 between them.
  • the handle with the opening is used to handle the plunger, for pushing in or pulling out.
  • the force exerted on the trigger lever 4 force is transmitted to the double ram via a feed system, not shown here, wherein a feed member of the feed system to the feed teeth 6 on the rams, see Fig. 4, is transmitted.

  • the metering teeth 11 and 12 may be formed substantially finer than the feed teeth 6 in order to achieve the finest possible dosage of the discharge volume. Analogous to the advancing teeth, the teeth of the metering toothing can be sawtooth-shaped, but in the opposite direction to the advancing toothing, since the plunger is not moved forward by this metering toothing but its feed is to be blocked, ie. H. It should be transmitted to the ram a backward force.
  • the locking member has in its center on a guide 14 which engages in the slot 15 of the double plunger. Through the guide, the limiting device is guided and secured by the counter-holder from falling out.
  • the guide could also be attached to the backstop.
  • a movable bushing 17 is inserted, which is acted upon by a compression spring 18 such that the counter-holder is lifted from the plunger surface, so that the metering teeth pressed on the locking part in the corresponding Dosiervertechnikung on the plunger becomes.
  • a compression spring 18 is provided per metering toothing, wherein the compression spring does not necessarily have to be arranged in a bush, and as a rule the limiting device has one metering tooth per plunger 2A and 2B.

  • the double plunger 23 is comparable to the double plunger 2 and has the two plungers 23A and 23B with the handle 23C and the handle opening 23D and the feed teeth 24.
  • the limiting device 25 has a lower locking part 26 and an upper counter-holder 27.
  • the limiting device, or its counter-holder 27, is provided on both sides with a metering toothing 28A, 28B, which is in engagement with the metering toothing 29A, 29B on the double tappet 23.

  • the front part of rod 30 passes through an opening 32 on the rear side 33 of the housing 34 of the discharge device in the discharge direction. At the edge 35 of the opening 32, the scale can be read. It can also be provided two or more rods, which then require a corresponding number of openings in the housing.
  • the scale bar 30 can be mounted on either side of the double pestle, or on both sides to enable a better reading. Of course, any appropriate graduation of the scale can be used.
  • any double ram position it is possible with the above device to set the limiting device together with the scale to a desired discharge volume. If the double ram is moved forward during discharge, the set volume can be accurately discharged, since when reaching the zero position of the scale, the limiting device is present at the rear edge of the housing.

Abstract

L'invention concerne un dispositif servant à limiter l'avancement d'un appareil de décharge à actionnement manuel pour composants multiples. Dans un mode de réalisation préféré de l'invention, ce dispositif comprend un coulisseau double (2) entraîné qui comporte une fente entre les coulisseaux individuels (2A, 2B), et des moyens (8) pour limiter le volume de décharge qui peuvent être fixés sur ledit coulisseau. Dans un mode de réalisation préféré, le dispositif de limitation (8) comprend une pièce de verrouillage (9) sur laquelle est disposée une denture de dosage (11, 11A) qui s'engrène avec une denture de dosage correspondante (12, 12A) se trouvant sur le coulisseau double (2). Selon l'invention, la pièce de verrouillage est soumise à l'action d'un ressort (18) pour comprimer les dentures de dosage l'une sur l'autre de manière libérable. Le dispositif de limitation selon l'invention permet d'ajuster, avec précision, le volume de décharge exact d'une cartouche double, y compris pour les appareils de décharge à actionnement manuel.
