PURPOSE: To make the structure of a device simple and to make the handling easy by connecting a pressure generation assembly consisting of a multi-axial direction piston pump and an electric driven motor to a handle of a pump housing and incorporating it into a head of an ejection gun. CONSTITUTION: An oblique plate 10 is fixed to the motor 3 with a flange in an axial direction piston pump and a pump shaft 11 and a pump housing 2 are attached to the oblique plate 10. Also a driven disc 12 is connected to the pump shaft 11 and plural pistons 13 are led displacably while being in contact with the oblique plate slant surface 15 in the disk 12. A sliding disk 17 is hermetically sealed and fixed to the driven disk 12 and a hermetically sealed disk 18 fixed to the pump housing 2 so as to come into contact with this disk 17 connects a cylinder of a piston 13 to a sucking path 19 or a pressure path 20. A jetting pipe is connected to the pressure path 20 and a water hose is connected to the sucking path 19 so that a low of water can be discharged with a high pressure.
