Hydraulic vs Mechanical Tensioners – A Technical Tip from

The hydraulic actuator works like a suspension strut, where a spring in combination with the damping feature of the oil, will keep the wheel in contact with the road. In this case, the hydraulic actuator controls the dynamic belt forces, while it also maintains a +/- constant belt tension, and compensates for length changes due to thermal expansion.

A gas spring is a hinge composed of a gas damper mechanism and a spring of sufficient strength to reduce the lifting weight of a lid. Industrial gas springs support heavy steel lids that may require gas spring shocks to offset the weight of the lid. A gas shock contains compressed gas and a gas prop is rated to support a specific weight.

Engineering Essentials: Fundamentals of Hydraulic Pumps

When a hydraulic pump operates, it performs two functions. First, its mechanical action creates a  vacuum  at the pump inlet which allows atmospheric pressure to force liquid from the  reservoir  into the inlet line to the pump. Second, its mechanical action delivers this liquid to the pump outlet and forces it into the hydraulic system.
