Abstract
Valves for use in a pressurized receptacle are disclosed including a housing and an orifice in the housing for dispensing a fluid, a shutter disposed in the housing and movable along the axis of the housing under the action of gravity between a closed position in which the shutter substantially closes the orifice when the valve is in a predetermined orientation and a dispensing position in which the shutter releases the orifice, and an absorber disposed downstream from the shutter relative to the direction of flow of the fluid, the absorber adapted to absorb a propellant gas contained within the fluid and for releasing propellant gas upon a decreasing pressure in the area adjacent to the absorber.
