けでなく又、組立ての際に容器穴を通す噴密装置
の組付けもむずかしくなる。 In a spraying device well known in the art (DE 2632662), a parallel passage extends through a hole in the auxiliary valve casing above the auxiliary valve chamber and a hole in the bottom of the auxiliary valve chamber. ing. In the normal position, the closing plug of the auxiliary valve rests against the valve seat surrounding the lower hole of the auxiliary valve chamber, so that this closing plug closes the parallel passage by its own weight and by the suction pressure generated by the piston pump. In the upside down position of the container, the parallel passage is closed by the stopper, which rests against another hole in the valve chamber by its own weight. Due to the suction pressure generated by the piston pump, the closure body is lifted out of the hole and liquid is therefore drawn up from the container laterally past the closure body and into the supply chamber of the piston pump. In this case, however, a fluid pressure is generated due to the suction of liquid, and the closing plug is pushed up to the opposite (in this case upper) hole and closes the auxiliary valve or the parallel channel. This effect is counteracted by the correspondingly heavy weight of the closing plug of the auxiliary valve. However, in some cases, the suction pressure of the piston pump may not be sufficient to dislodge the closure plug from the valve seat. The diameter of the auxiliary valve chamber is selected to be substantially larger than the diameter of the closure plug. In this case, not only does the cost of materials increase, but it also becomes difficult to assemble the injection device through the container hole during assembly.
本発明の目的は、容器のさかさま位置でも容器
液体の噴霧が同様にできしかも材料費、製作費及
び組付け費がわずかですむ前記したような装置を
提供しようとするにある。 SUMMARY OF THE INVENTION The object of the invention is to provide a device of the type described above, which can equally spray the container liquid even in the upside-down position of the container, and which requires only a small amount of material, manufacturing and assembly costs.
本発明によればこの目的は、補助弁室の壁の穴
をさかさま位置で補助弁の重力による作用によつ

ができる。 With this solution, in the upside down position of the container, the liquid can flow unhindered above the closure, without this closure being moved by fluid pressure into the closed state occupied by the closure in its normal position. Pass. The dimensions of the auxiliary valve can therefore be freely selected to be relatively small, and the auxiliary valve can be installed in the container at the same time as the spray device.
このようにして吸入管は吸入弁と共に補助弁に
自由に貫通して連結するのに役立つ。この構造に

組付けはさらに安価に又簡便になる。 In this way, the suction pipe together with the suction valve serves to connect freely through the auxiliary valve. This construction eliminates the need for a second auxiliary valve, making material costs and assembly cheaper and simpler.

が極めて短い。 With such a device, an auxiliary valve casing separate from the pump casing is arranged between the pump casing and the suction pipe, and a joint pipe is provided on the pump casing. According to the invention, this connecting pipe constitutes the intake valve casing and projects into the auxiliary valve casing alongside the auxiliary valve. In this case, the assembly of the pump housing and the auxiliary valve casing is simplified, and at the same time the parallel channel together with the auxiliary valve can be located considerably higher in the upper container chamber in the normal position of the container. In the upside down position of the container, virtually all of the liquid can be sprayed without leaving substantial residue within the container. In this case, when the container is upside down and the liquid level is below the inflow location of the parallel channel, the spraying action stops. Since the suction valve and the auxiliary valve are located next to each other at approximately equal heights, the vessel head space has a very short passage to the auxiliary valve and from the auxiliary valve to the suction valve.

全体をとくに樹脂から簡単に作ることができる。 Furthermore, an auxiliary valve casing is formed separately on the external part of the pump casing, and a suction valve chamber and an auxiliary valve chamber are arranged side by side.The auxiliary valve chamber is covered by an insertion piece formed on the external part of the pump casing, and this insertion part is Connect the valve chamber to the supply chamber of the piston pump. This construction allows the entire casing, including the pre-fitting of the valve prior to assembly of the insert piece and the casing, to be made particularly easily from plastic.

的細い頚部穴内径を持つ容器を使用できる。 The auxiliary valve housing is then advantageously located within the cross-sectional contour of the pump housing. In this case, the present spray device has a correspondingly narrow outer diameter, so that containers with a relatively narrow neck bore inner diameter can be used.

成する。 If the insert part is provided with a hollow fitting forming the intake valve casing, the insert part and the intake valve can be easily preassembled prior to assembly into the pump casing and the auxiliary valve casing. The attachment piece of the insert piece can be introduced into a corresponding hole in the auxiliary valve casing part. This hole forms at the same time part of the main passage and the parallel passage for feeding.

入部片により保護する。 With this device, the suction valve chamber and the auxiliary valve chamber are each provided with an upper hole in their normal position. Inhale liquid through this upper hole. According to the invention, these holes are formed especially for the introduction of the respective valve closing plug, and the introduction hole of the intake valve chamber is partially closed by the insertion piece. In this case, the closure plug can be simply introduced into each valve chamber and is protected by the insert piece within each valve chamber without interrupting the connection between the supply chamber and the suction valve chamber of the pump.

内につねに正しい位置に導入できる。 If the auxiliary valve closing plug is a ball, the diameter of this ball is larger than the smallest radial dimension of the chamber receiving the intake valve. In this case, the attachment of the auxiliary valve closing plug becomes easy. The auxiliary valve plug can always be introduced into the auxiliary valve chamber in the correct position without the risk of introducing the auxiliary valve plug into the chamber in which the suction valve is provided.

らに液体を噴霧することができる。 When the liquid container is in its normal position, that is, when the liquid container is upright and the spray head 1 is held upward and liquid is to be sprayed from the container, the piston 7 together with the spray head 1 is first moved by the force of the spring 12. Turn it upside down and press downward. In this case, the ball piece 19 is the valve seat 20
Therefore, the suction valve 11 is closed and the air retained in the supply chamber 13 flows through the outflow holes 14, 15, 1.
6, it is excluded to the outside. After the spray head 1 is released, the spring 12 pushes the piston 7 upwards;
Due to the throttling action of the bore 16 in the supply chamber 13, a reduced pressure condition is created. This reduced pressure state causes the ball piece 19 to move to the valve seat 2.
0, the passage of the supply chamber 13 of the piston pump 2, that is, the suction pipe 6, the hole 26, the valve chamber 25, the through hole 24, the valve chamber 21, and the hole 22 suck up the liquid from the lower part of the liquid container, and At the same time, the auxiliary valve 5 closes. This closure can also be achieved by reducing the pressure on the bulb 2.
This can be done reliably by using the weight of 8. When the spray head 1 or the piston 7 is pushed again, the suction valve 11
The liquid held in the supply chamber 13 is discharged to the outside through the outlet passages or holes 14, 15, 16 and is simultaneously atomized at the outlet end of the hole 16.
After the release of the atomizing head 1, the spring 12 tends to cause the piston return stroke to refill the supply chamber 13, so that further liquid can be atomized by the next piston stroke.

開いたままになつている。 When the spray head 1 is held facing downward in the upside-down position of the liquid container, both the bulb pieces 19 and 28 touch the protrusion 2.
It falls to 3,31. The liquid is then further transferred to the hole 26 by means of the parallel passage formed by the slit 32, the valve chamber 30 and the hole 33, provided that the liquid level is higher than the lower edge of the hole 26 at this point in the container.
6. The casing chamber 25, the bore 24, the valve chamber 21 and the bore 22 allow flow into the supply chamber 13 and into the bores 14, 15. Any air retained in the chambers 21, 13 escapes via the outlet channel. On the other hand, the liquid at normal pressure is prevented from flowing out by the throttle hole 16. First of all, the working stroke of the piston 7 causes a discharge of liquid from the supply chamber 13 through the holes 14, 15, 16 with simultaneous closure of the intake valve 11. During the return stroke that begins thereafter, liquid is again drawn into the supply chamber 13 via the parallel channels. In this case, since the weight of the bulb 28 is heavy, the auxiliary valve 5 cannot press the bulb 28 against the valve seat 29 by suction pressure against this weight, and therefore remains open.

気は流通して容器内空気圧平衡に役立つ。 The container chamber communicates with the outside, i.e. by a slit 35 in the peripheral wall of the pump casing 9 and an intermediate chamber 36 between the piston 7 and the pump casing 9, and also by a narrow throttle slit between the piston rod 8 and the bore 17 of the cap 3. This prevents liquid from passing through, but allows air to circulate, which helps balance the air pressure inside the container.

Compared to known spraying devices which are equipped with a suction tube 6 and a suction tube 6, and the suction tube 6 is pushed into a joining tube 10, these known atomization devices can therefore be used in an upside-down position without the need for an auxiliary valve. It is sufficient to simply insert the auxiliary valve casing 4 with the auxiliary valve casing 5 in between.

要がなくなる。製作もすべて簡単になる。 The embodiment shown in FIG. 4 differs from the embodiment shown in FIG. 3 in that the insertion piece 9c does not constitute the joint pipe 10, but instead forms a suction valve 11a in the chamber 25a of the auxiliary valve casing 4a. It's different. Therefore, the ball piece 19a
And the suction valve seat 2a is larger, and the hole 24a is formed directly in the auxiliary valve casing 4a. Ball piece 1
9a can be introduced unhindered by the hole 38 prior to the insertion of the insertion piece 9c. Both bulb pieces 19
A and 28 are made equal in size to each other, so that there is no need to distinguish between them during assembly or to maintain the position of the ball piece as far as this point is concerned. It also makes everything easier to manufacture.
