<P>PROBLEM TO BE SOLVED: To provide a pump which comprises a fixed suction part A equipped with a cylinder 3 for a liquid and a cylinder 4 for air and an operational jetting part B having a discharge port 5 attached to the suction part in an up and down movable manner and which is enabled to simultaneously jet out a liquid in the cylinder for a liquid and air in the cylinder for air by the up and down movement of the operational jetting part and capable of jetting a highly viscous liquid in airy and good touch foaming state. <P>SOLUTION: The pump comprises an air ventilation path a from a cylinder for a liquid to a discharge port and an air ventilation path b whose one end is communicated to a cylinder for air and the other end is joined to a liquid flow path. The latter end part of the air ventilation path b is positioned in the liquid flow path and a communication port p is formed in the peripheral part of the end part of the air ventilation path b to join the air ventilation path b at right angles in the liquid flowing direction in the liquid flow path. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
