How are hydraulics used in door closers?
Unlike gases, liquids can't be compressed. A great example of this is a medical syringe as illustrated below. A syringe is comprised of plastic cylinder known as the barrel which holds all the liquid. A plunger is located at one end of the barrel, while a small needle is located on the opposite end. The needle is hollow and this is where the liquid exits the barrel. When a nurse uses the syringe he or she pushes on the plastic plunger with their thumb using force. As the plunger pushes down into the barrel, we know that liquids do not compress. As a result the liquid has to move so it is forced through the small needle hole. When the liquid is forced through the smaller hole, it comes out at high speed since it cannot be compressed. The hydraulics in a door closer act in a similar manner in order to regulate the speed of the door closing.
