Abstract: The valve is for use on a gas pressurized liquid food dispensing container or can, such as a whipped cream dispensing can. The valve includes a dish-shaped, preferably metal can top connector having a vertical opening up through which extends the vertical rod portion of a valve stem disposed within a passageway in a vertical tubular portion of a rubber grommet. The upper end of the grommet engages the lower end of an expanded head on the stem rod to hold the stem yieldingly in place in assembly. The horizontal lower end of the grommet abuts the lower end of the connector and the upper end of the horizontal base of the valve stem so as to releasably seal the connector opening therewith. The valve stem base includes an inverted skirt peripherally mounted thereon that, with the lower end of the grommet define a circular path for dispensing the product.

Abstract: For use in a tilt action valve for dispensing a pressurized viscous product, in which a grommet is held by a mounting cup and secures the valve stem and body, product leakage between the grommet and valve stem is minimized by forming in the grommet a pocket which fills with the dispensed product and then lies tightly against the valve stem. The pocket causes the valve and grommet to be tilted with easier control. The pocket's operation simplifies the construction of the grommet and valve body, thus permitting dimensions which enable cheaper parts costs and assembly.

Abstract: Disclosed is a valve for use in a pressure-resistant container, permitting the full filling of the container with a liquefied gas thanks to a well controlled gas depletion path. The opening and closing of the depletion path is effected by bringing two opposing contact members apart and close to each other whereas the flow rate of gas depletion depends on the roughness of the contact surface areas of the opposing member. Such an appropriate depletion path can be made without difficulty such as encountered with formation of depletion path with recourse to machining.

Abstract: A tilt valve for an aerosol can is constructed so that it can be actuated only by transverse tilting forces. An output valve stem assembly is sealed to a valve housing whose inlet communicates with the interior of the aerosol can. A tilt element is biased against the bottom of the output valve assembly so as to seal the interior of the valve housing. A barrel-shaped spring is used to bias the tilt element so that the resistance of the output stem to tilting, and the stroke required for actuation, are reduced. The input stem and the bottom of the tilt element provide a secondary valve which is closed upon the output stem being subject to downward axial forces. Therefore, only transverse forces provided by an automatic actuating device can be used to actuate the tilt valve assembly.

Abstract: The disclosure provides a method and apparatus for effecting the noncontact opening of a flapper valve disposed downhole in a well. Such flapper valves may be located below a seal bore in a downhole tool such as a packer. An annular housing having external seals engagable with the seal bore can be positioned within the downhole tool. Fluid circulation through the annular housing during insertion is permitted by a ball valve mounted in its axial bore and engagable with a downwardly facing sealing surface. Upon engagement of the seals on the annular housing with the seal bore, the housing is converted into a piston and the amount of force exerted on trapped fluid between the annular housing and the flapper valve may be adjusted by adding weight from the tubing string. Fluid pressure above the flapper valve is increased to a level exceeding the closing forces on the flapper valve and the valve opens without any mechanical contact being made therewith.

Abstract: A novel valve mechanism using the so-called "rolling seal" type flexible cover tube. This cover tube is fitted fluid-tight on the outer circumference of a generally cylindrical inner movable valve member which is formed with an axial bore providing a fluid passage and which is further formed at its outer circumference with a valve port having communication with the axial bore. The cover tube has its at least one end radially turned or rolled radially outwardly to provide a turned annular lip where it is fitted on a fastened outer cylinder. Thus, the valve port is opened and closed by the outward and inward rolling motions of the annular lip of the cover tube due to the relative movements in the axial direction between the outer cylinder and the inner valve member. By the use of the valve mechanism thus constructed, a charging valve for a gas lighter can be provided.
