Description

The invention relates to a valve according to the preamble of the preamble of claim 1.

Such valves are obviously previously known in a variety of configurations.

DE 1058440 B relates to a valve for dispensing partial quantities from a pressurized gas container according to the preamble of claim 1.

The invention is based on the object to provide a generic same valve, which achieved by simple measures either a small spray flow / foam flow or a larger spray flow / foam flow of a liquid product from a spray nozzle / foam nozzle.

This object is achieved by the features of the characterizing part of claim 1.

The invention will be explained in more detail with reference to an embodiment.

It shows:

1 in an axial section, a fully assembled valve on a pressurized gas container with a spray head in a closed position;

2 the valve after the 1 , but in a first operating position (push position) and without spray head;

3 the valve after the 2 , but in a second operating position (push position);

4 the valve after the 2 but in a first tilted position, and

5 the valve after the 4 but in a second (opposite) tilt position.

The 1 shows a valve 1 for dispensing partial quantities from a pressurized gas container 2 where the valve 1 with a housing 3 is provided and one from the housing 3 leading out, spring-loaded tube 4 with an axial discharge channel 5 having. The pipe 4 is manually axially displaceable and / or tiltable and liquid-tight and on the start side inside the housing 3 with a valve plate 6 with an upper sealing collar 7 provided in a closed position on a first sealing disc 8th pressure and liquid-tight, wherein the tube 4 in a first push or tilt position A ( 2 . 4 and 5 ) the upper sealing collar 7 from the gasket 8th at least partially lifts off. This allows a liquid through the first flow channel 6 to flow with a relatively small current. The pipe 4 is below the sealing collar 7 with a lateral first flow channel 9 provided and with the discharge channel 5 connected. The delivery channel 5 is in axial continuation with a second flow channel 10 provided by the valve plate 6 is arranged therethrough. The distributor 6 is with a lower sealing collar 11 is provided in a closed position on a second sealing disc 12 pressure and liquid-tight, wherein the second sealing disc 12 on an axially movable valve element 13 is arranged and by a force of a compression spring 14 is charged. An inside floor 15 of the housing 3 is with an axial projection 16 provided, which is designed as a skewed cylinder, with a slanted cutting plane 17 of the projection 16 with a pointed cone, axial end 18 of the valve element 13 so corresponds that through the pipe 4 in a second thrust position B ( 3 ) the axial end 18 from the crooked cutting plane 17 is tilted, the second sealing disc 12 from the lower sealing collar 11 partially lifted off. This additionally allows a further flow of liquid through the second flow channel 10 flow, whereby the liquid flows add and thereby a larger Spühstrom (foam flow) is generated. For a flow of a liquid product from the inside of the pressurized gas container 2 to the valve 1 is the case 3 with a flow opening 19 Mistake. For upright spraying from the pressurized gas container 2 is as a flow opening 19 the lead 16 with the ground 15 with a third flow channel 2 provided and has on the outside a receiving pin 21 for a riser 22 on. Instead of a spray head 23 a per se known, not shown foam head can be provided. Advantageously, the valve 1 and a valve seat 24 - except for the compression spring 14 made of spring steel - made of plastic. But it can also be a compression spring 14 be provided from plastic. As a liquid to be sprayed or foamed, for example, a cosmetic hair care product can be provided. Also, the compressed gas tank 2 be made of suitable plastic.
