Abstract:
1. A pressure regulated flow valve for dispensing product from a pressurized container, the pressure regulated flow valve comprising: a valve housing within a pressurized container, the valve housing defining a product flow path and having an upper chamber accommodating a valve stem and a lower chamber accommodating a gas piston cylinder comprising: a passageway for dispensing variable amounts of product through the valve housing; and wherein the passageway has a variable sized opening defined by the flow controller according to the position of the piston within the gas piston cylinder, the flow controller increasing the size of the opening and increasing the amount of product dispensed through the passageway as the piston moves towards the maximum outward position, the position of the piston within the gas piston cylinder being dependent on a relative difference between the pressure of the gas piston cylinder chamber and the pressure of the container.
