How does a hydraulic door closer work?
As the door is opened, a powerful spring on the inside of the closer is compressed or tightened. When the door is released, this spring pulls the door shut. To keep it from slamming shut, a cushioning or shock absorbing medium is used. This may be either air (in pneumatic closer) or fluid (in hydraulic closer).
