(57) Abstract:The invention relates to sprayers, which in the initial position include thermosensitive outlet means in contact with the spindle. In the dispenser spindle is installed in the channel with the inlet for fluid and an outlet to preferably inclined nozzles and moves with the possibility of sliding or almost slide along the channel walls located on both sides of the inlet for the fluid to balance the liquid pressure in the inlet opening for the liquid when the dispenser is in its original position, nozzle, centrally directed relative to the inclined nozzles, located at the end of the spindle facing the outlet means. The technical result of the invention is to provide a dispenser that provides a uniform live load on the exhaust means and ensure uniform spray extinguishing medium in the form of an aerosol. 5 C.p. f-crystals, 3 ill. The present invention concerns a dispenser, which in the initial position includes a thermosensitive outlet means being in close contact with the spindle. More specifically, the invention carked for admission quenching medium at least one nozzle, when this spray in the initial position includes a thermosensitive outlet means being in close contact with a movable spindle located in the passage for the fluid and having an inlet opening and an outlet opening to the nozzle.The exhaust means may be, for example, a glass ampoule, which is destroyed at high temperatures. In order to ensure quick action, it is necessary that the ampoule was as thin as possible. Even a thin vial has a resistance sufficiently heavy mechanical load, if the load exerts pressure directly on the end of the ampoule and uniform.SE 501267 discloses a dispenser of this type. However, the known spray prevents high liquid pressure to prevail in the input hole for liquid when the dispenser is in its original position, and therefore rapid action spray impossible. In this liquid spray high pressure will influence like a powerful load on the exhaust means so that the discharge means will be destroyed. In order to avoid destruction, the outlet should have a special design.The present invention javljaetsja not so great, that outlet may just collapse under the action of liquid pressure when the nozzle is in its original position.The atomizer in accordance with the invention differs in that the liquid passage comprises a channel along the walls which moves the spindle slidable or almost slip, while the spindle, and a channel passing to both sides of the inlet channel at least partially balance the liquid pressure in the inlet opening when the dispenser is in its original position, and the nozzle, centrally directed relative to the inclined nozzles located at the end of the spindle facing the outlet means.Offer options atomizer disclosed in the accompanying paragraphs.2 to 4.Hereinafter the invention will be described in more detail with reference to the variant of the invention shown in the accompanying drawings, where:
Fig.1 is a longitudinal section of a variant of the invention in the initial position,
Fig.2 shows the dispenser of Fig.1 in the current situation,
Fig.3 - view of the dispenser with an end face that is visible from below.The dispenser 1 includes a housing 2, which is attached to the ceiling 4 mnozhestvennymi hole 6. Further, the dispenser has a sleeve 7, which includes a housing 8, which is attached to the housing 2 of the dispenser, through, for example, the head 9, is screwed into 8 Central hole 6 and the hollow in him.The head 9 of the housing 8 of the sleeve includes a multiplicity of holes 10, which are connected via the filter 11 with the inlet for fluid 5 and lead to the Central channel 12 located in the head 9. The Central channel 12 is branched off through the outlets 13 in a variety of inclined nozzles 14. The spindle 15 is mounted for sliding and the Central channel 12 of the body 8 of the sleeve. When the dispenser is in its original position, as shown in Fig. 1, the spindle 15 is sealed in the cylinder 9 by means of a spacer 16, located below the inlet for the liquid 10. The Central channel 12 passes through both sides of the entrance holes for the liquid 10 in order to prevent too strong influence of liquid pressure on the spindle 15 when the dispenser is in its original position.The spindle 15 also has a Central hole 17 (hereinafter called the spindle hole) that is lower than the axial subsidence 16 is connected through the holes 18 with the Central channel 12 of the head 9 and thence through the outlets 13 with nozzles 14.Force of the spring 22 and (usually very small) ring area of the strip 16, which is in the input holes 10 acting fluid pressure, are of such dimensions that they do not destroy the ampoule when her temperature is normal in the initial position, as shown in Fig.1. If part of the spindle 15 which is located above the gasket 16 is in close contact with the surrounding wall of the head 9 located on both sides of the inlet 10, the liquid pressure is fully balanced, and only the spring 22 exerts pressure on the spindle.In the initial position depicted in fuerste spindle 17 and the nozzles 14, a direct link is blocked by the gasket 16.If the vial 20 is broken or, at least, is deformed due to hot gases or strong heating by the heating coil (not shown) and pressed under the force of the spring 22, as shown in Fig 2, the spindle 15 is lowered down until the shoulder 23 located on the spindle, not tightly bonded with the flange 26 of the housing 8 of the sleeve. The spindle 15 is sufficiently long distance and provides the passage of fluid from inlet 10 through the channel 12 in the cylinder 9, which is located after the strip 25 into the hole 17 of the spindle and then to the nozzle 14 through the holes 18 located in the spindle 15.Nozzle 14 preferably should be of such kind, so that they can operate at high pressure and spraying liquid in the form of liquid aerosols in accordance with the patent application PCT/FI92/00155.Before install the sleeve 7 to the housing 8 of the sleeve to position the vial 20 and the spindle 15, which includes the spring 22. Then the sleeve is fully installed. So it is possible to easily perform clean installation without damaging the capsules, which are sensitive to shock and uneven load.Part of the outer end 21 of spindola 14, spiral spring 28 around the axis of the nozzle fitting 29. In the operating position shown in Fig.2, the liquid flows not only from the nozzles 14, but also from the holes 17 of the spindle through hole 30 located between and along the spirals of the spring 28 in the nozzle hole 31, and extends through the inclined surface 32 located on the outer end of the holder 19.The Central nozzle 27 located at the end of the spindle 15, provides a continuous spray produced by the spray. 1. The dispenser includes a housing that has at least one nozzle, the housing has an inlet for fluid and holes for receiving the quenching medium at least one nozzle, and the spray in the initial position includes a thermosensitive outlet means being in close contact with the spindle, including the hole in the spindle, and the spindle is mounted for movement in the channel with inlet and outlet to the inclined nozzles to ensure movement of the spindle slidable or almost slide along the channel walls, while the nozzle, centrally directed relative to the inclined nozzles, there are ndat to both sides of the inlet channel and at least partially balance the liquid pressure in the inlet, when the dispenser is in its original position.2. Spray under item 1, characterized in that the spindle is sealed by a gasket between the inlet and the place of entry of the fluid hole of the spindle against the insert member into the opening when the dispenser is in its original position while the spindle is made with offset so that the connection from the inlet, located after the strip to the end of spindle hole is opened when the nozzle is in the working position, and the Central directional nozzle is a continuation of spindle hole.3. Spray on p. 2, characterized in that the seal between the inlet and the place of entry of the fluid hole of the spindle includes an annular gasket installed on the door.4. Spray under item 1, characterized in that the spring is located in the bore of the spindle, resting partly in the flange located in the axial channel, and partly in the cover, ensuring the movement of the spindle when the dispenser is in the working position.5. Spray under item 1, characterized in that the holder exhaust means has at least one inclined spray surface on radiusy points, characterized in that the lower part of spindle hole has a spiral fluid channel defined by a spiral spring, put on allow the fitting.
