PROBLEM TO BE SOLVED: To provide a reciprocating pump type ejector which can sufficiently agitate a mixture of a liquid and a powder and ejects the mixture. SOLUTION: In a reciprocating pump P, a pressurized chamber 30 is formed using an ejection pipe 15, a piston 28, and a cylinder 20. A check valve 24 which opens/closes the inlet of the chamber 30 and a ball-shaped agitation member 25 for agitating the contents in the chamber 30 are installed in the chamber 30. On the other hand, in the pump P, besides the chamber 30, a suction space 29 is formed using the piston 28 and the cylinder 20. A communication hole 20e for discharging the mixed contents which were sucked up when a push down button 17 was returned to the original position into a container 10 when the button 17 is pushed down is installed in the space 29. |
