Claim 0:
1. A grease gun comprising:
a body able to be connected to a container configured to store grease, the body defining first and second elongate chambers therein, the first chamber extending along a first axis and the second chamber extending along a second axis, the first axis being spaced from the second axis, and the second chamber having a smaller cross-sectional area than the first chamber;
first and second pistons, the first piston configured to reciprocate within the first chamber along the first axis and the second piston configured to reciprocate within the second chamber along the second axis, the second piston having a smaller cross-sectional area than the first piston;
primary and secondary grease channels, the primary grease channel being disposed between the container and the first chamber such that the container is able to be fluidically connected to the first chamber, the secondary grease channel being disposed between the first and secondary chambers, and intermediate a length of the second chamber, such that grease is able to flow from the first chamber into the second chamber;
an actuator connected to the body and moveable between a retracted position, whereby grease is able to flow through the primary grease channel, and an engaged position, whereby grease is restricted from flowing through the primary grease channel, the actuator being configured to cause reciprocation of the first piston and the second piston when moved between the engaged and retracted positions; and
a grease outlet fluidically connected to the second chamber that allows for grease to be discharged from the grease gun.
