ABSTRACT:
A cylinder 12 is positioned along the vertical axis. A piston 16 and a trigger 18 are provided respectively with a pair of racks 40 capable of meshing with a pair of pinions 38 of a housing 14. By way of the pinion pair 38, pivoting motion of the trigger can be converted into a reciprocating movement of the piston along the vertical axis. It is thus possible to increase the amount of discharge of liquid in one stroke of the trigger without inducing for example a drop in operability upon molding.
