Abstract
A product transfer device is provided that includes telescoping tubular arm sections that collectively define a fluid passageway and are arranged so that a terminal arm section has the smallest diameter, while the diameters of the succeeding arm sections are increasingly larger. Piston seals in adjacent arm sections cooperate to define a chamber. A product transfer valve and isolation valve control the flow of product through the product transfer device. Pressurization of the passageway extends the arm sections and an actuator device opens the product transfer valve when the transfer arm contacts a container bottom. Pressurization of the chamber causes retraction of the arm sections so that the exterior of each arm section is wiped clean by the piston seal of the arm section into which that arm section is retracted. Retraction of the arm sections also operates a securing device that automatically shuts the product transfer valve.
