FLUID SPOUTING DEVICE

Japanese Patent JP2635523

B2

PURPOSE: To provide a fluid spouting device less in number of part items and versatile by fixing a trigger to a part of a piston exposed from a cylinder.
CONSTITUTION: A step is made between a large inner diameter part on one side of a cylinder and a small inner diameter part of it of which both ends are formed in large inner diameter and of which center part is formed in small inner diameter, a large inner diameter part on the other side is interconnected at a taper with the small inner diameter part, and an O-ring 11 is installed in the small inner diameter part near the stage. Also a piston 2 provided with a nozzle of which inside is hollow and which is fitted closely at a clearance into the larger inner diameter part and the small inner diameter part can be slid from the side on which the stage of the cylinder 1 is provided while airtightness is maintained. Then a packing 4 installed on the end part near the tapered part 1e of the piston 2 is provided with a through-hole 2e which is interconnected with the hollow inside the packing at a position where the packing is not removed due to tightening of a screw located at the end part of the piston 2, the side not in contact with the screw of the packing 4 is made in contact with the tapered part 1e for airtightness, and the packing does not move to the position of an O-ring 11 in an area where the piston is slidable, and a trigger 12 is fixed to the piston with a screw 5.
