High viscosity oil suction and dispensing tool
First Claim
1. A suction and dispensing tool for sucking and dispensing a fluid such as a high viscosity oil from/to a gear box and the like comprising:
- a cylinder storing the fluid;
a nozzle attached to a front end of said cylinder;
a piston moving forward and backward in said cylinder;
a piston rod for driving said piston, the rod extending in a length direction of said cylinder and projecting through a rear end of said cylinder opposite to said nozzle; and
two ratchet type driving mechanisms for selectively feeding said piston rod forward or backward,wherein said driving mechanism comprises;
a frame having a handle, the frame mounted to said cylinder and guiding said piston rod in a slidable manner; and
two triggers rotatably attached to said frame relatively at a front side or a rear side of said handle, and to be rotated toward said handle so as to move said piston rod forward or backward.

Abstract
A suction and dispensing tool (1) comprises: a cylinder (10) storing the fluid; a nozzle (20); a piston moving forward and backward in the cylinder (10); a piston rod (40) for driving the piston; and two ratchet type driving mechanisms (60) for driving the piston rod (40) forward and backward. The driving mechanism (60) comprises: a frame (50) having a handle (52), mounted to the cylinder (10), and two triggers (80) rotatably attached to the frame (50) at the front and rear sides of the handle (52). By rotating each of the triggers (80) to the handle (52), the piston rod (40) can be moved forward or backward. The rotating operation of the trigger (80) requires power smaller than an operation for directly pushing and drawing the piston rod by hand. Accordingly, it becomes possible to refill and dispense a high viscosity oil easily.
