Abstract
A nozzle and valve assembly comprises a cylinder having an open end and a piston having a conical deflecting surface on its lower end. A first supply pipe is connected to the interior of cylinder through an aperture in its wall. A second supply pipe is connected through a bore formed in the wall of the cylinder to an inwardly directed orifice positioned at the bottom of the cylinder. In use, with the piston in a raised position, a solid product is supplied through the first supply pipe and discharged through the open end of the cylinder into a container. The piston is lowered, thereby closing off the aperture in its wall and hence the first supply pipe, until its lower end is level with the inwardly directed orifice. Liquid is then supplied through the second supply pipe. The liquid washes away any solid on the conical deflecting surface and is formed by the conical deflecting surface into a smooth slow flowing column of liquid.
