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.
Claims20
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 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.
