ABSTRACT:
A valve mechanism is provided for use in an inhaler comprising a pressurized container, and a metering chamber, and a valve mechanism wherein the inlet and outlet valves are separate and can be operated independently. The pressure of the fluid in the canister is used to aid the opening of the outer valve so reducing the force to fire a dose. A variant of the valve mechanism allows the user to select from a range of dose volumes by appropriate orientation of the stem.
