Title (EN) MECHANICALLY OPERATED DISPENSING DEVICE WITH EXPANSIBLE BULB
(FR) DISTRIBUTEUR A FONCTIONNEMENT MECANIQUE POURVU D"UN BULBE EXPANSIBLE
Abstract: front page image
(EN)The purpose of this invention is to provide an aerosol dispenser, which does not rely upon atmosphere deteriorating chemical propellants for discharging the product, wherein a long duration, high pressure spray or discharge of the product is obtained. An easy to operate dispensing device has a rotatable actuator (20) connected with an expansible chamber (P, 51, 52) to effect operation of the expansible chamber to draw material to be dispensed from a container (C) into the expansible chamber (P, 51, 52) and to then pressurize the material. An expansible bulb (B) is connected with the expansible chamber and with a dispensing nozzle (H.90), and has a volumetric capacity several times as great as the expansible chamber. Valves (94, 96, 97, 98) are associated with the bulb control flow into and out of the bulb. The relative sizes of the expansible chamber and bulb are such that a hydraulic force multiplication is obtained from the expansible chamber into the bulb.
(FR)Distributeur d"aerosol dont le fonctionnement ne requiert pas de propulseur chimique degradant l"atmosphere, et qui permet de pulveriser ou de distribuer le produit sous haute pression et pendant une longue duree. Un dispositif distributeur facile a utiliser possede un organe d"actionnement rotatif (20) relie a une chambre expansible (P, 51, 52) afin que celle-ci preleve le materiau a distribuer depuis un conteneur (C) et ensuite mette ce materiau sous pression. Un bulbe expansible (B) est relie a la chambre expansible ainsi qu"a une buse de distribution (H. 90) et presente une capacite volumique plusieurs fois superieure a celle de la chambre expansible. Des vannes (94, 96, 98) permettent de controler le debit a partir du bulbe et vers celui-ci. Les dimensions relatives de la chambre expansible et du bulbe sont telles qu"une multiplication de la force hydraulique est obtenue depuis la chambre expansible dans le bulbe.
