Tubular T-shaped nozzle assembly for treating fluids

Claim 1

An apparatus for treating fluid products comprising: a tubular body having a longitudinal passage and an intersecting passage which intersects the longitudinal passage at a tubular body junction which defines and separates the longitudinal passage into first and second passage portions, the first passage portion, at a position adjacent the junction, being beveled inwardly in a direction towards the junction for providing a first valve seat; a first nozzle member which extends longitudinally within the first passage portion and is mounted for reciprocative longitudinal displacement in the first passage portion, the first nozzle member comprising (i) a beveled end valve member portion which increases in cross-section from a nozzle end for, upon longitudinal displacement of the first nozzle member towards the junction, fluid-tight contact against the first valve seat; and (ii) a bore through the first nozzle member which opens into the first passage portion for providing fluid communication in the first passage portion from the bore to between the valve member portion and the first valve seat when the valve member portion is displaced from the first valve seat and so that the fluid communication is sealed off when the valve member is in fluid-tight contact with the first valve seat; and a second nozzle member which extends longitudinally within the second passage portion and is mounted for reciprocative longitudinal displacement in the second passage portion and which has a longitudinal bore which terminates in an outwardly beveled portion for providing a second valve seat for, upon displacement and positioning the first nozzle valve member portion and the second valve seat against one another, fluid-tight contact between the valve member portion and second valve seat.

Claim 2
