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.

Claim (Index 10):
The trigger-type ejector according to  claim 6 , wherein,\n the trigger-type ejector further comprises a foaming portion provided in the ejection hole and foaming a liquid ejected from the ejection hole; the nozzle head includes an inner cylinder wall surrounding the communication hole and including, in the inner periphery, at least one rear groove that communicates with the outlet of the flow path; and the ejector body includes a column disposed inside the inner cylinder wall rotatably and liquid-tightly relative to the inner cylinder wall and provided with, in an outer periphery, at least one front groove that communicates with the communication hole, thus the nozzle head is rotatable relative to the ejector body between an ejection capable position where the rear groove and the front groove communicate with each other and an ejection incapable position where communication between the rear groove and the front groove is blocked.
