Abstract:
An improved valve assembly having a material inlet, a metering chamber and a port. A valve element reciprocates within a valve passageway, such that in a first condition, a flow path is created for material to flow from the inlet to the metering chamber and the valve element forms a metal-to-metal seal of the flow path to the discharge port. The valve element then slides to the second condition, to unseal the passageway to the discharge port, and forms a metal-to-metal seal of the flow path to the inlet. A piston forces the material out of the metering chamber, and because the flow path to the discharge port is unsealed and the flow path to the inlet is sealed, the material is directed from the metering chamber, to the discharge port, where it can be dispensed as desired.

Claim (Index 1):
A valve assembly for dispensing a metered quantity of flowable material, comprising:\n a material conduit formed with metal and having a proximal end and a distal end opposite the proximal end, the conduit including a first opening distal the proximal end, a second opening distal the first opening, a belt section between the first and second openings, a neck section distal the second opening and a third opening, distal the neck section; the first opening adapted to receive a flow of the material to be dispensed; the second opening in fluid communication with a metered container adapted to receive and dispense a selected volume of the material; a valve element formed with metal, slidably disposed within the conduit, and selectively displaceable between a proximal retracted position and a distal extended position, the valve element having a base portion with an outside diameter matching the inside diameter of the belt section of the conduit, a waist portion of reduced diameter distal the base portion and a head portion distal the waist portion, the outside diameter of the head portion matching the inside diameter of the neck section of the conduit; the valve element and conduit adapted and configured such that when the valve element is in the retracted position, the head portion forms a metal-to-metal first seal with the neck, such that material forced through the first opening, into the conduit, will be directed to flow into the metered container and not past the first seal and when the valve element is in the extended position, the base portion forms a metal-to-metal second seal with the belt section and material forced out of the metered container will flow through the neck, past the head, into the third opening and not past the second seal.
