Abstract
A trigger-type ejector includes: a pressure storage chamber formed in a nozzle head and communicating with a flow path through a communication hole; a pressure storage plunger including a large-diameter pressure receiving portion opposite a small-diameter pressure receiving portion and being movable between a close position where an ejection hole is closed and an open position where the ejection hole is opened; and a biasing member disposed in the pressure storage chamber and biasing the pressure storage plunger toward the close position, the trigger-type ejector being configured such that, when a pressure of a liquid in the pressure storage chamber becomes equal to or greater than a predetermined value, the pressure storage plunger moves from the close position to the open position against a biasing force of the biasing member and thus a liquid in the pressure storage chamber is ejected from the ejection hole to the outside.
