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 19):
A valve assembly for dispensing metered quantities of high viscosity fluids into containers, comprising:\n a valve element with a longitudinal axis having a head portion formed with metal and having an end that flairs out to provide a frustoconical contact surface that is inclined to the longitudinal axis of the valve element at an angle of about 15\u00b0 to 85\u00b0 to the longitudinal axis of the valve element, the contact surface having a Rockwell hardness over about 20 Rc; and a stop surface meeting the contact surface to form a metal-to-metal seal.
