Definitions
- the present invention relates to a chargeable hand- sprayer to be used for gardening or the like, when an un ⁇ complicated portable handsprayer may be required, e.g. for weed killing.
- an elastic bladder such as a rubber bladder, connectable to a water pipe under pressure, has been disposed in a pressure vessel.
- the bladder On supplying pressurized water to the bladder, the latter will expand and in doing so will compress surrounding air contained in the pressure vessel, which air will pressurize the liquid present in the vessel for spraying.
- the handsprayer When an adequate amount of pressurized water has been supplied to the bladder, the handsprayer is charged. By opening and closing an adjustable nozzle connected to the handsprayer the latter may then be used for emptying and spraying of the liquid contained in the vessel.
- an inflatable rubber bladder 2 which is connectable to an external pressure source, such as an existing water pipe connected to a water system under pressure, by means of the liquid pressure in the water system the bladder may be filled with water and caused to expand thereby compressing an air volume 3 present in the container and surrounding the bladder, i.e. charging the sprayer, the container prior to charging having been, for example, half filled with a suitable liquid 4.
- the compressed air will then act on a liquid surface 5 in the container 1.
- a valve 6 in an adjustable spraying nozzle 7 connected to the sprayer under the liquid level 5 spraying of the liquid will be possible because of the air pressure in the container.
- the spraying nozzle is connected via a junction 9 to a tube 10 for the spraying liquid, the lower opening 11 of the tube being under the liquid surface near the base of the container.
- a conventional connecting means 12 the water pipe is connectable to the rubber bladder of the container, where a cut-off valve 13, or a standard tap, may be provided for cutting off the water supply.
- the container is also provided with a screw cap and a handle 14.

Abstract
Afin de pouvoir utiliser, dans un pulvérisateur à main, de l'eau sous pression en tant qu'énergie d'entraînement de divers liquides, on a placé dans un récipient sous pression (1) une vessie élastique (2), telle qu'une vessie en caoutchouc pouvant être reliée à un tuyau d'eau sous pression. Lors de la fourniture d'eau sous pression à la vessie, celle-ci se dilate et ce faisant comprime l'air (3) environnant, contenu dans le récipient sous pression, lequel air met ensuite sous pression le liquide (4) présent dans le récipient, aux fins de pulvérisation. Lorsqu'une quantité adéquate d'eau sous pression a été fournie à la vessie, le pulvérisateur est chargé. En ouvrant et fermant une buse réglable (7) reliée au pulvérisateur, on peut utiliser celui-ci pour vider et pulvériser le liquide contenu dans le récipient.
