Abstract: A nozzle for injecting a viscous fluid, such as a molten plastic and a non-viscous fluid, such as a gas, includes a nozzle body having an inlet end, a discharge end and a flow passage for viscous fluid extending from the inlet end to the discharge end. A shut off valve device is provided for reciprocating in the nozzle body flow passage to control the flow of viscous fluid through the nozzle body discharge end. The shut off valve device includes a valve body and a non-viscous fluid flow passage provided in the valve body. A baffle device is located in the non-viscous fluid flow passage of the shut off valve for retarding a flow of viscous fluid in the non-viscous flow passage.

Abstract: A plumbing connection is disclosed to connect a supply conduit to a faucet. A supply conduit has a main cylindrical body portion with an expanded, end portion. The supply conduit is received in a valve mounting body having a commensurate throughbore and counterbore which are adapted to respectively engage in slidable contact the cylindrical main body portion of the supply conduit and the expanded end portion of the supply conduit. A resilient seal member with projections having throughbores is received in wedged contact within the expanded end portion of the supply conduit. A valve is removably secured to the valve mounting body and in contact with and in communication with the throughbores of the supply conduit and the seal member.
