Title
(EN) DUAL LIQUID SPRAYING SYSTEM
(FR) DISPOSITIF D'ASPERSION A DEUX LIQUIDES
Abstract
(EN)
A manifold (88) for use with a hand held pump spray device (10) allowing the spray head (12) to draw simultaneously from two separate reservoirs (16, 18) containing two different fluids such that the spray head (12) raises a mixture of the two fluids in a predetermined ratio. The manifold (88) includes at least one ball check valve arrangement (82, 116, 120) in the suction line (104) to the chemical concentrate reservoir (18), the ball check valve (116) being normally biased to a closed position. The check valve (116) prevents the pumping of the concentrate when the diluent reservoir (16) is spent and further prevents cross contamination between the two fluids in the two reservoirs (16, 18) due to syphoning.
(FR)
Un diffuseur (88), s'utilisant avec un dispositif (10) d'aspersion à pompe tenu à la main, permet à la tête d'aspersion (12) de puiser simultanément dans deux réservoirs séparés (16, 18) contenant deux fluides différents, cette tête pouvant ainsi effectuer un mélange des deux fluides selon un rapport déterminé. Le diffuseur (88) comporte au moins un dispositif à soupape à boulet (82, 116, 120) disposé sur la conduite d'aspiration menant au réservoir (18) de produit chimique concentré, cette soupape (116) étant normalement comprimée en position fermée. Elle prévient le pompage du produit concentré quand le réservoir de diluant (16) est vidé, ainsi que la contamination croisée entre les deux fluides des deux réservoirs (16, 18) due à un effet d'aspiration.
