The opening of the door twists the skein further, when the door is released the rope's torsional force pushes the arm back against the door, thereby closing it.
How does a manual door closer work?
A manual door closer stores the energy used in the opening of the door in a spring, either a compression, torsion, tension, volute or leaf. and releases it to close the door. Some closers allow for adjustment of the strength of the spring, making it easier or more difficult to push the door open along with providing more closing force. To limit the door’s closing speed, most door closers use oil-filled hydraulic dampers. This provides soft closing. Other types use a friction-based mechanical speed control mechanism. The absence of an oil damper makes mechanical closers more resistant to drastic temperature changes.

Closer development
The first door closers consisted of just a spring mechanism only, as time went on the rate at which the door closed was arrested or checked by adding an additional checking device. Door closers at this time were known as a door spring and check. Later these two devices were combined into one unit that both closed the door and slowed the speed at which this was done. These early "door closers" used a pneumatic piston to check the speed, later models used a hydr…

• Concealed in floor
Control of closing force and speed
Hydraulic and pneumatic closers often feature dampers that offer control over the closing force and speed. Hydraulic closers are known for providing soft closing. Mechanical closers, on the other hand, also provide closing force and speed control but by using object friction rather than oil. The absence of an oil damper makes mechanical closers more resistant to drastic temperature changes.
Usage
Door closers are most commonly installed on bathroom doors, fire doors, and exit doors in commercial buildings. During a fire, any door that penetrates a firewall must be fire-rated.
