ABSTRACT:
A valve assembly for use with an aerosol container for controllably dispensing a substance disposed within the container under pressure of a propellant also contained therein. The valve assembly provides a high degree of precision control in the dispensing of the substance using a rotary actuator cooperatively engaged with a camming arrangement which transfers large rotary motion into small valve displacing linear motion. The valve is sealed by a resilient gasket which is protected from the deteriorating effects of chemicals in the substance and/or propellant by a flexibly deformable Teflon liner.
