PROBLEM TO BE SOLVED: To provide a pressure accumulation system syringe type air mixed liquid jetting unit for jetting a small quantity of content fluids including air in a bubble shape.SOLUTION: A bubble jetting unit 1 comprises an operation part 10 and a jetting part 20. The operation part comprises a cylinder, a piston for pushing out air of the cylinder to a tip cylinder 11c and a rod 14a projected from the tip cylinder part 11c by forming an air introduction passage between the tip cylinder 11c and itself. The jetting part comprises an outer cylinder part 21 having a jetting port 1a and installed in the tip cylinder part 11c and an inner cylinder part 22 having an opening part A communicating with the jetting port 1a and arranged in the outer cylinder part 21. The inner cylinder part is incorporated with a piston 26 for pushing out the content fluid M, a conical elastic valve 25 diametrically expanding toward the opening part A, and a spin element 24 for imparting torque to the content fluid M from the elastic valve, and a liquid passage rfor making the content fluid M from the opening part A flow to the jetting port 1a and air passages r-rfor making the air from the introduction passage flow to the liquid passage rby a confluent part r, are formed between the outer cylinder part 21 and the inner cylinder part 22. |
