Vapor tap valve for aerosols

摘要

Vapor tap valve for use in particular with fluids having a propellant gas which is inmiscible. A number of passages for the liquid/gas mixture between the interior of the valve shell where single entry points are provided, separate for the liquid and for the gas; these passages abutting on the passage of the actuating stem of the valve. A better mixing of the gas with the liquids is obtained with a path for a gas access to the interior of the outlet valve as short as possible up to the outlet passage of the valve. The incoming extra gas enters immediately next to the inner surface of the sealing gasket.
