T-Seal for polymeric extrusion system

摘要

An improved sealing means is provided in a multiple component assembly for delivering a fluid material under pressure which includes a lower fluid material container section having a cavity formed therein and provided with at least one outlet orifice formed in an outlet surface of the lower fluid material container section, which outlet orifice communicates with the cavity, an upper fluid material container section formed in at least two parts which are arranged in juxtaposed mating relationship and which define a cavity therein, one of the juxtaposed parts having a fluid material inlet in an inlet surface, the inlet communicating with the cavity in the upper fluid material container section. The upper fluid material container section is mounted in superposed mating relationship on the lower fluid material container section and the upper fluid material container cavity is arranged to communicate with the lower fluid material container cavity and thereby define a fluid material chamber. A first sealing means is provided between the mating surfaces of the lower fluid material container section and the upper fluid material container section and is arranged surrounding the fluid material chamber. A second sealing means is provided between each of the at least two parts of the upper fluid material container section adjacent the cavity in the upper fluid material container.
