  • Patent number: 10302202
    Abstract: A valve assembly for modulating flow of a fluid through a valve may include a plunger, a flange with an orifice, a first disc with an orifice, a second disc, a gasket in contact with both the flange and the first disc, three bearing members disposed between the first disc and the flange. The three bearing members define a position and orientation of the first disc with respect to the flange, and separate the first disc from the flange, thereby defining a gap between the flange and said disc. The plunger displaces the second disc surfaces from a first position to a second position.

  • Patent number: 10240679
    Abstract: A high conductance valve for use in fluid delivery systems is comprised of a flat non-circular orifice ridge adjacent to which a control plate having a planar control surface is proximally positioned to adjust the valve effective opening area and thereby the conductance of the valve. The length of the non-circular orifice ridge periphery is substantially greater than the circumference of a similarly sized circular orifice and therefore the realized effective opening area is also substantially greater despite having a similar footprint.

  • Patent number: 10173521
    Abstract: A tube extends through an attachment section and defines a vapor passageway. A housing is supported to the attachment section for movement between several positions relative to the attachment section. The housing defines a float chamber below the tube. A valve seat portion is located within the float chamber and has an engagement part, a sleeve part and a seat surface. The engagement part is connected to the housing. The sleeve part telescopically engages the tube and is movable along the tube with the housing. The valve seat portion defines a central bore open to the vapor passageway and the seat surface. The float moves within the float chamber. When to fluid enters the float chamber the float floats up against the seat surface closing off the central bore and the vapor passageway. In the absence of fluid the float moves downward exposing the seat surface.
