- latching means (722) are dimensioned so that a sufficiently strong pressure on the piston head (7) must be exercised so that it engages the top of the piston (64), and is preferably provided with one or more raster elements, the possible Balances can compensate.
- the height of the cylindrical Hauptteiis (31) of the inner shell (and thus the height of the upper cylindrical portion (22) of the outer shell) selected so that when the Koibenech (6) is in the upper position in which the first piston (61) on the radial connecting wall (23) abuts, there is sufficient space in the interior of the inner shell for the cylindrical part (62) and the detached, not locked piston head (7).
- Such a two-chamber unit is intended to be mounted on dispensing means such as a two-way valve (4) or a two-way pump. It is also possible to provide only Sch thoroughlymittei that are opened during the dispensing process.
- the dispensing means may comprise dosing means so that upon actuation of the dispensing means a predetermined amount of each of the products is dispensed.
- Two-way valves are b e k n n t, b e i p l e s e a d u c u e n te n S 3, 9 1 5, 345 A o d e r WO 2007/132 017 A1.
- the valve body (41) comprises a first part in the form of a downwardly bulged collar (42) and a second central part in the form of a cylindrical pin (43), wherein the part in the form of the collar (42) surrounds the peg-shaped part (43) ,
- the collar-shaped part (42) is provided at its lower end with retaining means, which are complementary to those (27) of the outer shell (2).
- These holding means are dimensioned so that a tight connection between the outer jacket (2) and the collar-shaped part (42) is provided.
- the pin-shaped part (43) is dimensioned so that it penetrates into the sleeve (33) of the inner shell and also ensures a tight connection.
- the valve is provided with two separate ways, from one in the space between the collar (42) and the pin (43) and the other in the interior of the pin (43) opens.
- the delivery module (1) is mounted on the valve (4), the first chamber opens in the first path and the second chamber in the second path of the valve.
- the unit consisting of the two-chamber dispensing unit (1) and the dispensing elements (4) can then be fastened in a housing (5). If the dimensions of the delivery unit (1) and in particular the outer diameter of the outer shell (2) and / or the diameter of the valve disc (44) of the delivery means allow this, the delivery module (1) can be inserted into the inner area of a prefabricated housing. Otherwise, it is necessary to form the housing (5) around the dispensing module (1). This is the case with the example shown in the figures.
- a first advantage of the dispensing module is the fact that it is possible to use housings of any shape, in particular housings with curved or profiled exterior.
- a second advantage is that deformations of the housing have no influence on the functioning of the pistons. While in the prior art, the slightest bump could hinder the sliding of the piston on the housing or its deformation could cause a leakage of the first chamber, the container provided with the dispensing module according to the invention is shock resistant.
- FIG. 3 shows a container provided with a delivery module (1) attached to a two-way valve (4), the two-way valve (4) being fixed on the neck of the housing (5).
- the gas is already introduced into the housing and exerts a pressure on both the first piston (61) and on the second Kol ben (64) or in the present case on the Koibenkopf (7).
- the container can now be filled with the two products. This starts with the first product over the first one Way of the dispensing means (4), then fill the openings (281) and the channels (24) in the first chamber (20).
- the piston unit (6) is pushed back by the incoming product pressing on the piston (61).
- the second piston has a separate piston head (7), it remains in its initial position, ie in the upper region of the second chamber (30), while the upper part (64) of the Koiben unit (8) is displaced from the first piston (7). 81) is pressed down.
- An opening (642) in the top of the Koibenech (6) prevents the formation of a vacuum between the fixed piston head (7) and the downwardly running upper part of the piston (64).
- the rim (63) of the first piston (61) strikes against the annular radial wall (82) of the retaining means (8) as shown in FIG.
- the second product can now be filled via the second path of the valve (4) and the pin (43), and the sleeve (33) in the second chamber (30).
- the incoming product pushes the piston head (7) downwards.
- the gas in the space between the inside of the cylindrical part (62) of the piston unit is expressed via the opening (642) in the top part (64) of the Koibenritt.
- the pressure exerted by the second product on the piston head (7) is sufficient to overcome the resistance of the latching means (641, 722) and lock the piston head (7) into the piston unit (6).
- the two pistons (61, 84) are now coupled together and can only move simultaneously. This corresponds to the situation illustrated in FIG. It only needs a spray head on the rod (45) of the valve are plugged and possibly a protective cap can be applied.
- the container is ready for use. Thanks to the separate piston head (7) it is possible to fill the container with two separate filling units.
- the second piston is formed directly on top of the piston unit (6), this side has no opening (842), the shutdown of this top, which takes over the role of the piston, air in the second chamber (30), which forms simultaneously with the first. Therefore, the air contained in this second, already formed chamber (30) must be sucked off before the second product is filled.
- the chambers (20, 30) form only when filling the product. If a separate piston head (7) is provided for the second chamber (30), this (30) will not be formed simultaneously with the first chamber (20). On the contrary This forms only when filling the second product. It is therefore not necessary to provide a suction device for removing the air from the second chamber before the second product is filled. Depending on the composition of the products used, it is necessary, after filling the first chamber and before filling the second chamber and possibly also after filling the second chamber, the parts touched by the products to avoid undesired reactions between the product and the product kten or to avoid their contamination.
- the ratio between the initial volume of the first and second products is determined by the ratio between the area of the first (61) and second pistons (64).
- the dispensing module thus allows a very high precision in terms of the ratio of the initial volume of the two products. Due to the area ratio between the area of the first piston (61) and the second piston (64), it is also possible to fill the second chamber (30) with a higher pressure than the outside pressure.
- first piston (61) can also be formed with a separate piston head.
- the piston head is then annular and filling begins with the second chamber (30) and not with the first chamber (20) when only the first piston has such a piston head.
- the height of the first cylindrical portion (21) of the outer shell and / or the cylindrical portion (62) of the piston unit must be sufficiently large to allow the piston unit (6) to fully penetrate into the inner shell, with strikes her upper part without the annular piston head engages in the piston unit (6).
- the second piston (64) is also provided with a separate piston head (7).
- the dispensing module (1) is used on a pressure vessel, as is the case in the example shown here, then it may be useful to the unit consisting of the dispensing unit (1) and the dispensing means (4) in the housing (5) fasten, wherein the Ventiiteller (44) is not mounted on the housing (5). This makes it possible to fill the propellant during filling before the Ventiiteller (44) is mounted on the housing (5).
- a fork (9) is provided which the Blocked unit so that the tip of the second cylindrical portion (22) of the outer shell abuts against the inner side of the top of the housing (5).
- This removable fork (9) penetrates into a groove (28) which is provided for this purpose at the tip of the outer jacket (2) below the fastening means (27),
- valve plate (44) it is also possible to attach the valve plate (44) to the housing (5) of the pressure vessel, then fill the dispensing module (1) and add the gas through an opening in the bottom of the pressure vessel, which is then closed , If the gas is filled from above, it must be ensured, for example, by channels provided for this purpose that the gas can flow to the bottom.
- Suitable propellant gas for discharging the product are, in particular, compressed gases, such as nitrogen, oxygen and compressed air, as well as liquefied gases, such as hydrocarbons, for example butane and isopentane, dimethyl ether and fluorine hydrocarbons.
- compressed gases such as nitrogen, oxygen and compressed air
- liquefied gases such as hydrocarbons, for example butane and isopentane, dimethyl ether and fluorine hydrocarbons.
- hydrocarbons for example butane and isopentane, dimethyl ether and fluorine hydrocarbons.
