Definitions

  • the inventive product is available for portable use, in particular for accessories that are suitable for 5 taking and transporting a specified fluid supply.
  • the largest invention is most beneficial to call in biochemical, biological, chemical studies, and non-negligence.
  • the pressurized part 20 of the lower part of the mobile movable is located at the very end, which is supplied to the upper part of the circuit.
  • the lower part of the consumable part of the product, in the case of a quick change of the gear, the pressurized part is separated from the outside part of the pressurized part,
  • the regulating sleeve On the upper part of the housing, the regulating sleeve is located with a threaded hole in its lower part, which is raised to the upper part above the housing.
  • the free-wheeling section of the bushes is in a fixed grip with a movable nut installed in the inside of the casing. ⁇ top
  • the unit has a fixed storage compartment located on it, below which is located the exhaust plate.
  • a mobile unit In the case of a mobile unit, it is also installed in the same unit as the auxiliary unit, a recharged external drive for the first time. If you move the unit down, it is in direct contact with the lower side of the unit, which is in the lower position, which is in the lower position.
  • the desired dose value is set at a reading of 0 mechanical counts.
  • the dose value is set with the required precision in the form of directly counted decimal numbers.
  • One thing to do with the change in the dose to the other is to constantly rotate the set nut, all the other 5 times are necessary.
  • Another disadvantage is that, moreover, the comprehension of the mechanism of installation and the calculation of the dose rate is easy, which in turn increases the size and weight.
  • the invention includes, in particular, a cabinet that has an upper part and a small lower part that is worn on a removable case.

We recommend that you carry out a good, normal, positive housing in the opposite direction.
  • an optional installation nut must be supplied with a cylindrical, large exact dose count.
  • a good version of the installed nut allows you to set the dose rate with increased accuracy, orienti 30, breaking down on the nut.
  • the good performance of the regulating hub further improves the grip between the hub and the gears, increasing the reliability and durability of the device.
  • a good execution simplifies the circuit and raises it further, combining in one detail the function of ensuring the mechanical communication of the details and the indication.
  • FIG. 2 is shown on an enlarged scale 'the upper part of the 20 filaments, in a cut; Fig. H - from W to W in Fig. 4, Fig. 4 shows the view of the nut on the cylinder nut.
  • Piston 5 and position 6 can be made in the form of a plunger, which has a uniform cross section for the entire length, just like - 7 - shown in FIG. ⁇ annually, or have a different diameter in different places in length.
  • Juvenile Lane 8 is registered in the Republic of Uzbekistan on rotation of the East. For this, for example, the Regulatory Blade 8 may have a distinct flatter with a 90 ° angle, but it may be slightly overlooked.
  • the unit 10 is located on the side of the button 10; the unit is used as unit 6;
  • the installation nut II (Fig. 1.2) is located with the option of its rotational rotation and the possibility of accommodation in the direction of the installation.
  • Nut II is designed to take up two positions, one of which is located in the center of the thread .
  • the cassette has a simple visual counting device, made in the form of a toothed gear 12 (Fig. 2,3), which is located in the constant shutter speed of 8 and
  • Boom 15 can be performed, for example, in the form of a separate part of housing I, or to provide a separate nest in housing I, which can be accommodated in II.
  • the new nut II may be equipped with a cylindrical box of 5 left 18 (Fig. 4) exact calculation of the dose.

  • gear 12 can be offset
  • such a mechanism can be performed in the form of a sleeve 20 Fig. 1, 2) an alternating drive and an outdoor unit 21, which is a second-time unit.
  • the outermost part of the hub of 20 is above the upper part of 2 degrees.
  • the force of compression of the wedge is 21 on the other hand, that is, at the expense of the button 7, in the case of the hub of 20 there is a noticeable noticeable change in the movement to the further movement of the " 7. - "
