Abstract
Apparatus for dispensing material in metered amounts and without clogging includes a body having a material discharge orifice and a discharge valve seat, a hollow valve spindle engageable with the seat for shutting off the flow of material through the orifice, the spindle being retractable against the force of the return spring for opening the orifice to permit flow of material therethrough. A jet of air is discharged through the hollow valve spindle, when the flow of material through the discharge orifice is shut off for removing any material remaining at the discharge orifice. The spindle may project through the orifice, when the flow of material therethrough is shut off, for removing any residual material from the wall of the discharge orifice. And, a coaxial hollow tube for dispensing another material may be provided in the body, such tube forming an annular passage with the spindle for the jet of air, and such tube extending through the orifice for combining the dispensed materials outwardly of the discharge orifice.
