Abstract:
A pumping mechanism (300) includes a barrel assembly (310) having a plunger bore (320). The plunger bore (320) has a longitudinal axis. The pumping mechanism (300) also includes a plunger (330) configured to slide within the plunger bore (320) parallel to the longitudinal axis. The pumping mechanism (300) further includes a push rod (114) separate from the plunger (330). The push rod (114) is configured to move away from the plunger (330) to be spaced from the plunger (330), and the push rod (114) is further configured to move within the plunger bore (320) to push the plunger (330).
