  • Patent number: 6223746
    Abstract: A metered dose inhaler pump for delivering a metered dose of an active compound from an active compound inlet through a spray outlet without the need of a pressurized active compound container. Reciprocating action of an inlet valve, an outlet valve and a plunger alternately draw a metered dose of the active compound from an active compound container into an active compound chamber and pressurize the drawn metered dose of the active compound to eject the metered dose through the spray outlet. The plunger substantially fills and evacuates the metered dose chamber, leaving no void head space therein.
