A second valve member has a second seat surface with a tapered contour facing axially upstream. The second valve member has a closed position in which the second seat surface abuts the first seat surface, and has an open position in which the second seat surface is spaced axially downstream from the first seat surface. The second valve member further has a terminal end portion configured as a nose cone. The nose cone may be located entirely downstream of the second seat surface, and may have a cavity with a drain opening.

  • Patent number: 6035752
    Abstract: A scrap cutting assembly for use in a reciprocating press in which a cutter is carried on a ram which reciprocates with respect to a fixed base to form and cut material passing through the press includes an exit plate mounted on the press base adjacent the material exit point and a shutter spring and backing spring attached to the exit plate. The exit plate has a tapered bottom surface which tapers upwardly toward the ram and the shutter spring and backing spring are attached to and lie along the bottom tapered surface with one end of the shutter spring extending beyond the end of the exit plate and slightly above the top surface thereof so as to support the material as it is fed through the press. The shutter spring is depressed by the cutter as the ram and cutter descend to sever the material.
