A cartridge (100, 414, 502, 502', 502", 1100, 1300, 1350, 1902', 1902") for dispensing fluid (214, 610, 1302, 1302', 1516). The cartridge comprises a valve (110, 1100), wherein the valve comprises a pumping chamber (118, 1118) for pumping the fluid. The valve is operable for positioning a pumping chamber conduit (120, 1120). The pumping chamber conduit is connected with the pumping chamber. The cartridge further comprises a plunger (1108) operable for changing the volume of the pumping chamber. The cartridge further comprises a reservoir conduit (124, 1214) for connecting the reservoir with the valve. The valve is operable for positioning the pumping chamber conduit to connect with the reservoir conduit. The cartridge further comprises an outlet conduit (128, 1128) for dispensing the fluid. The rotary valve is further operable for rotating the pumping chamber conduit to connect with the outlet conduit. |
