A door closer is a mechanical device that regulates the speed and action of a door ’s swing. [1] Manual closers store the force used to open the door in some type of spring and reuse it to close the door. Automatic types use electricity to regulate door swing behavior. Door closers can be linked to a building's fire and security alarm systems.
Electro-hydraulic—the motor drives a hydraulic pump, which pressurizes the oil in a door closer, which in turn turns the door closer and opens the door. This is the preferred type in Europe. (In the US it has a reputation of being prone to oil leaks.) Electro-pneumatic—the motor drives an air compressor and may be located away from the door.
When the hydraulic door-closer at Corner Gas breaks, Brent takes Lacey’s advice and hires the best door guy in the business to fix it. The repairs go well, but when Brent tries to fine-tune the new device on his own, he earns the scorn of a true professional.

Car hydraulics are equipment installed in an automobile that allows for a dynamic adjustment in height of the vehicle. These suspension modifications are often placed in a lowrider, i.e., a vehicle modified to lower its ground clearance below that of its original design. With these modifications, the body of the car can be raised by remote control.
An ornate brass door hinge A barrel hinge. A hinge is a mechanical bearing that connects two solid objects, typically allowing only a limited angle of rotation between them. Two objects connected by an ideal hinge rotate relative to each other about a fixed axis of rotation, with all other translations or rotations prevented; thus a hinge has one degree of freedom.

Hydraulic pump. A hydraulic pump is a mechanical source of power that converts mechanical power into hydraulic energy (hydrostatic energy i.e. flow, pressure). Hydraulic pumps are used in hydraulic drive systems and can be hydrostatic or hydrodynamic. They generate flow with enough power to overcome pressure induced by a load at the pump outlet.
