<p>PROBLEM TO BE SOLVED: To provide a trigger type pressure accumulation spray which can discharge a liquid smoothly with a good efficiency and increase durability of a spring.SOLUTION: A trigger type pressure accumulation spray includes a vertical circulation part 1c in which a liquid pushed out from a cylinder structure 3 is circulated, a lateral circulation part 1a which is connected to the vertical circulation part 1c at a connection part 1b, and a trigger part 6b for moving a piston 5 in a cross direction. The connection part 1b has a flow channel in an oblique direction which connects a vertical flow channel of the vertical circulation part 1c to a lateral flow channel of the lateral circulation part 1a, and the vertical circulation part 1c, the connection part 1b and the lateral circulation part 1a are integrated to one another. A first valve 4, which opens and closes a flow channel through which the liquid is introduced into th cylinder structure 3 from a sucking part 10, is accommodated in the cylinder structure 3, a second valve structure 2, which opens and closes a flow channel in the connection part 1b, is attached to the connection part 1b, and said second valve structure 2 is energized to a valve seat 1b1 of the connection part 1b diagonally upwards.</p> |
