Abstract
Embodiments of the invention provide a probe assembly configured to selectively restrict fluid flow through an outlet of a closed transfer system. The probe assembly has an elongate probe body with a top end portion, a bottom end portion, an outer wall, and an internal structure defining a fluid chamber extending from the bottom end portion to the top end portion. The fluid chamber has a fluid chamber inlet at the bottom end portion extending through the outer wall into the fluid chamber and a fluid chamber outlet at the top end portion extending from the fluid chamber through the outer wall. A probe tip with a cylindrical bore is configured to engage the top end portion of the elongate probe body and a probe tip outlet is configured to be in fluid communication with the fluid chamber outlet. A rotating head located circumjacent to the probe tip and adjacent to the probe tip outlet is configured to rotate about the probe tip. The rotating head having an inner surface, an outer surface, and a vane extending from the inner surface through the outer surface.
