to refer to like parts for the sake of convenience only the differences relative to the first embodiment 20 will be discussed in detail the system 120 utilizes an off set single piston actuator 52 a having a housing 54 a with a larger lateral dimension than the housing 54 of the system 20 thus the first described system 20 is preferred if lateral space is restricted the present embodiment is slightly simpler in design and therefore preferred if space permits similar to the system 20 the system 120 has a hot runner nozzle body 24 having an inlet 26 to be coupled to a source of pressurized melt discharged by a machine nozzle not shown the nozzle body 24 also has an outlet 34 disposed about a first axis 44 the nozzle body 24 defining a melt channel 36 extending from the inlet 26 to the outlet 34 the melt channel has an end portion 42 located adjacent to the outlet 34 and disposed about the first axis 44 the nozzle body 24 also has an offset body portion 46 located between the inlet 26 and the end portion 42 and being laterally offset relative to the first axis 44 the actuator 52 a is external to and positioned laterally from the.
