Origin of plunger¹

First recorded in 1605–15; plunge + -er ¹

You can draw the plunger up and down and it looks as if the blood is mixing with the liquid.

Trying to pull the plunger back would snap the ring and effectively break the syringe.

It is a cast-iron plunger-pole, over the shaft, of 33 inches diameter, 10-feet stroke.

The unsupported pump-rods fell downwards, setting in upward motion the column of water in the plunger-pole pumps.

I have made the plunger-case and steam-vessel of wrought iron ¾ of an inch thick.

The valve open while the plunger-pole ascended 20 inches, then went the remainder of the 10-feet stroke expansive.

The function of this plunger is to provide a resistance in addition to that of the air valve spring to assist in acceleration.
