A gas spring is a type of spring other than typical mechanical spring
that generally relies on elastic deformation.
As a result of the hydraulic pre-stressing, similar to a mechanical spring
, a considerable energy saving is achieved, in total - 30 % could be detected within the project.
Two identical parallelogram mechanisms (PM) serve as the mechanical spring
[23-25] as shown in Figure 2(a).
The impedance function, as the major part of the controller, simulates the dynamics of a mechanical spring
combined with a viscous damper.
For the proposed OLEA system, the single engine cylinder is opposed by a mechanical spring
to return the translator for the compression stroke.
One of the advantages of air springs is that the energy-storage capacity of air is far greater per unit weight than that of mechanical spring
material, such as steel.
Valve types include a 5/2way single solenoid valve, which for safety applications can have a mechanical spring
return; a 5/2-way valve with double solenoid and a 5/3-way valve, which can be exhausted, pressurised or closed in mid-position.
A new line of palletizing lifts includes both mechanical spring
and air spring self-leveling models, as well as electric hydraulic units that provide more precise positioning.
Electric hybrid--Electro-hydraulic actuators typically rely on an electric power source to create hydraulic pressure for compressing a mechanical spring
"Air suspension is great in terms of stability on the highway but is no good when you're travelling on bumpy farm tracks," he said "We've used mechanical spring
leaf suspension - a greatly beefed up version of what we have used so successfully on our livestock trailers for many years.
The joystick has a mechanical spring
that is tuned to provide the proper amount of resistance for precision control.
