• a chamber, in fluid communication with the reservoir, formed by the wall of the plunger, the fixed wall of the inner cup and the window;
• wherein a rotation of the plunger relative to the inner cup causes the plunger wall to move between a first position and a second position relative to the fixed wall;
• wherein rotation of the plunger changes the volume of the chamber;
