To provide a delivery pump for preventing fluid dripping from a nozzle section after a delivery operation.
This delivery pump 1 includes: a cylinder section 3; a piston section 4 capable of sliding in the axial direction of the cylinder along the inner peripheral surface of the cylinder section 3; an operation section 5 for operating the piston section 4; a tubular suction section 6 communicated with a liquid chamber 32 in the cylinder section 3; an openable/closable suction valve 7 that is arranged inside the suction section 6 and is opened in interlock with a pull-back operation of the piston section 4; a cylindrical nozzle section 8 that projects toward a side of the cylinder section 3 and is directly connected to the cylinder section 3 to be communicated with the liquid chamber 32; and an openable/closable delivery valve 9 that is arranged inside the nozzle section 8 and is opened in interlock with a pressing operation of the piston section 4. The delivery valve 9 can move in the axial direction of the nozzle section 8 while the closed state exhibiting the sealability is maintained.
