A three position plunger is provided including a sleeve having an opening at a distal end a pre load cavity proximal to and in communication with the opening a first cavity proximal to and in communication with the pre load cavity a second cavity proximal to and in communication with the pre load cavity and at least one rib. The rib(s) is generally aligned with the first cavity.
