20090017153 | Rotary Valve Assembly for an Injection Nozzle - A rotary valve assembly for an injection unit is provided, having a valve body, defining a melt channel for a working fluid. At least one end cap is mounted to the valve body, the valve body and the at least one end cap cooperatively defining a valve seat intersecting the melt channel in a generally traverse direction, the valve seat having a wider portion and a narrower portion. A spool defines an orifice, the spool being rotatably mounted within the valve seat, and is movable between an open position where the orifice is aligned with the melt channel and a closed position where the orifice is misaligned with the melt channel. | 01-15-2009 |
20090028987 | Sliding Valve for an Injection Nozzle - A shut-off valve assembly for an injection unit is provided. It includes a first valve body, defining a portion of a channel, and a second valve body, defining a second portion of the channel, the second valve body being slidable relative to the first valve body. A plunger having an orifice therethrough, is located between the first valve body and the second valve body, and is selectively movable between an open position where the orifice is aligned with the channel and a closed position where the orifice is misaligned with the channel. Compressing the first valve body and the second valve body together while the plunger is in the open position creates a positive face seal around the orifice, thereby reducing leakage in the shut-off valve assembly. | 01-29-2009 |
