摘要： A rotary valve assembly (30, 130, 230, 330, 430, 530) for an injection unit (20) is provided, having a valve body (32, 132), defining a melt channel (28) for a working fluid. At least one end cap (38, 138, 238) is mounted to the valve body (32, 132), the valve body (32, 132) and the at least one end cap (38, 138, 238) cooperatively defining a valve seat (36) intersecting the melt channel (28) in a generally traverse direction, the valve seat (36) having a wider portion (42) and a narrower portion (44). A spool (54, 154) defines an orifice (70), the spool (54, 154) being rotatably mounted within the valve seat (36), and is movable between an open position where the orifice (70) is aligned with the melt channel (28) and a closed position where the orifice (70) is misaligned with the melt channel.
