Each rotary valve member has a single passageway and is mounted for movement between positions in which (a) the passageway communicates with the tube carrying the foam component and (b) the passageway communicates with a tube carrying the cleaning solution, thus permitting cleaning of the dispenser at all points downstream of where the foam components enter the valve. The distance between where the foam component is introduced into the dispenser and the point where the foam component enters the valve is so short that no significant amounts of buildup of the foam component can occur.

Abstract: This disclosure relates to a manually operated, self-cleaning, aerosol valve that is adapted to maintain separation of fluids while they are within the valve body. The valve is internally separated by a sealing gasket that cooperatively engages a valve seat, and an outwardly projecting discharge passageway stem member. When the valve is in a nonoperating state, engagement of the gasket with respect to the valve seat prevents discharge passage of a first fluid to the stem passageway, and engagement of the gasket with respect to the stem prevents discharge passage of a second fluid. In cofluid dispensing state, first and second ports into the stem discharge passageway are positioned on opposite sides of the gasket. This allows first and second fluids to separately enter the stem passageway, and maintains separation of fluids awaiting discharge. When the valve is operated in positions intermediate the shut and cofluid dispensing state, both first and second fluid ports are positioned to receive first fluid only.

Abstract: A self-cleaning valve used at the outlet of a container has an elongated flexible flattenable tube with an inlet end for receiving material to be dispensed from the container and an outlet end for dispensing the material. In the at-rest condition of the valve, a section of the tube extending from the outlet end is supported between a housing surface and a closure-cleaning lever member spring-mounted on the housing so that it pivots about a fulcrum. By pressing down on one end of the lever member, the tube can be opened so that material, forced out of the container, can be dispensed from the outlet end of the tube. After the material has been dispensed, the lever member is pivoted along the outside surface of the tube pressing the tube against the housing surface so that any material remaining within the tube is forced out of the outlet end.

Abstract: The applicator for applying adhesive to a work piece, for example in an edge glueing machine for work pieces moving continuously through the machine, has adhesive discharge holes (6). The adhesive is supplied through these holes (6) under pressure to the edge of work pieces. Any contaminating particles, which may be present in the adhesive prior to its application to the work piece, tend to travel upwardly with the adhesive in the adhesive supply conduit (2, 4), due to their lower specific weight, whereby the contaminations may clog the discharge holes (6) and prevent the proper application of adhesive to a work piece. For avoiding such clogging the nozzle body (1) is provided with a scavenging duct (5) which is connectable to the adhesive supply conduit (2, 4) for repeatedly passing a portion of adhesive out of the supply conduit (4), whereby the application of adhesive may be performed without any trouble. The discharge holes (6) are closed during the scavenging of a small portion of adhesive.

Abstract: A self-cleaning valve used at the outlet of a container has an elongated flexible flattenable outlet tube with an inlet for receiving material to be dispensed from the container, and an outlet for dispensing the material. In the at-rest condition of the valve, a pair of spring-biased rollers contact the opposite sides of the tube at a location spaced from the outlet end and hold the tube in a closed condition. When material is forced through the inlet end of the tube it pushes the rollers toward the outlet against the spring biasing action. At the outlet end the rollers separate and permit the tube to open so that the material can be dispensed. After the material has been dispensed, the springs return the rollers to the at-rest position and the rollers effect a self-cleaning action on the tube.

Abstract: This disclosure relates to a manually operated, self-cleaning, aerosol valve that has separate control elements for propellant fluid and product fluid. The valve is adapted to maintain internal separation of the fluids. Even when the fluids are codispensed to produce a fine mist, separation of the propellant from the product is maintained until the fluids are beyond control elements. Control elements also maintain internal separation of the fluids when the valve is actuated for purging. This is achieved by keeping the fluid product control element closed while the propellant control element is open. With the control elements so positioned, cleaning fluid can be directed to purge all passageway surfaces that are exposed to external air. This type of valve is particularly suited for dispensing viscous products, such as water-borne paints.
