ABSTRACT:
A device for accurately displacing a fluid within a chamber. The device includes a barrier wall (38) which separates the fluid (12) to be displaced from another fluid, a rod (32) and a concentric elastomeric tube (34) disposed about the rod and passing through an aperture in the barrier wall, securing structure (58) which secures the ends of the elastomeric tube (34) about the rod (32), a resilient annular element (44) carried by a cavity (48) formed within the barrier wall, and structure to compress the resilient element so that it is forced radially inwardly to seal the resilient tube about the rod. The space between the rod (32) and the tube (34) to either side of the resilient element (44) is filled with a lubricant.
