Patent number: 7341169Abstract: Self-purging, low force opening, aerosol valve system with an orificed valve stem groove and gasket forming a first valve for product and propellant, or propellant, flow. A check valve element, biasing element and housing first opening form a second valve for product flow. Actuating the valve stem sequentially opens first valve and then second valve. After actuation, second valve closes before first valve, and propellant from housing second opening purges valve stem and actuator until first valve closes. No first valve closing return spring acts directly on valve stem, allowing easy opening. Gasket in stem groove and product and propellant flow fully close first valve after second valve closes. High solid and/or resin content products can be dispensed through an actuator with mechanical break-up insert.Type: GrantFiled: April 5, 2005Date of Patent: March 11, 2008Assignee: Precision Valve CorporationInventor: Christian Bayer
