Abstract
A valve (1), particularly for an aerosol container, includes, inside a valve body (2), an inlet passage (4) communicating with the container and an outlet passage (10), a first elastic return (16) for urging the valve (1) into the closed position, and a regulator for regulating the product outlet flow rate, which includes a second elastic return (14) for supplying a set-point pressure for the regulator. The second elastic return (14) is arranged in a compartment (12) of the valve body (2) isolated from the product, the pressure inside the compartment (12) being equal to atmospheric pressure.
Claims46
A valve for a container, comprising:
- a valve body;
- an inlet passage provided in said valve body configured to communicate with a container;
- an outlet passage communicating with the exterior of said container;
- means for selectively communicating the outlet passage with said inlet passage in response to an actuation command;
- first elastic return means for urging the valve into a closed position;
- and
- regulating means for regulating a product flow rate through said valve, comprising second elastic return means for supplying a set-point pressure for said regulating means, said second elastic return means arranged in a compartment of said valve body isolated from a product to be discharged from the container, wherein a pressure inside said compartment is substantially equal to atmospheric pressure.
A container for dispensing a product under pressure, this container being equipped with a valve, said valve comprising:
- a valve body;
- an inlet passage provided in said valve body configured to communicate with a container;
- an outlet passage communicating with said inlet passage;
- means for selectively communicating the outlet passage with said inlet passage in response to an actuation command;
- first elastic return means for urging the valve into a closed position;
- and
- regulating means for regulating a product now rate though said valve, comprising second elastic return means for supplying a set-point pressure for said regulating means, said second elastic return means arranged in a compartment of said valve body isolated from a product to be discharged from the container, wherein a pressure inside said compartment is substantially equal to atmospheric pressure.
A valve for a container, comprising:
- a valve body:
- an inlet passage provided in said valve body and configured to communicate with a container;
- an outlet passage communicating with the exterior of said container;
- an opening/closing element for selectively communicating the outlet passage with the inlet passage;
- a barrier which is movable to control a degree of opening/closing of an outlet orifice in communication with the outlet passage;
- a first elastic return element positioned to urge the opening/closing element into a closed position;
- and
- a second elastic return element positioned in a compartment of said valve body which is at atmospheric pressure and which is isolated by said barrier from a product to be discharged from the container, said second elastic return element pressing on said barrier in opposition to the pressure of the product to be discharged from the container.
A container for dispensing a product under pressure, the container having a valve comprising:
- a valve body;
- an inlet passage provided in said valve body and configured to communicate with the container;
- an outlet passage communicating with the exterior of said container;
- an opening/closing element, for selectively communicating the outlet passage with the inlet passage;
- a barrier which is movable to control a degree of opening/closing of an outlet orifice in communication with the outlet passage;
- a first elastic return element positioned to urge the opening/closing element into a closed position;
- and
- a second elastic return element positioned in a compartment of said valve body which is at atmospheric pressure and which is isolated by said barrier from a product to be discharged from the container, said second elastic return element pressing on said barrier in opposition to the pressure of the product to be discharged from the container.
A valve for dispensing a product from a container, comprising:
- a regulating chamber defining an inlet orifice, an outlet orifice, a first compartment and a second compartment, wherein said first compartment includes said inlet orifice to receive said product, and said second compartment is isolated from said first compartment so that said second compartment is isolated from said product in said first compartment;
- a movable divider disposed inside said regulating chamber between said first and second compartments;
- and
- a positioning device disposed in said second compartment such that said positioning device is isolated from said product in said first compartment, said positioning device being coupled to said movable divider so as to position said movable divider in at least a first position and a second position,
- wherein said product passes through said outlet orifice when said movable divider is positioned in said first position and said product cannot pass through said outlet orifice when said movable divider is positioned in said second position.
