DA Series Rate
Controls
|
| |
|
The DA Series Rate Controls by
Enidine Incorporated are ideally suited for high-energy,
heavy load applications requiring rate control
in tension, compression or both directions. These
non-adjustable, custom-orificed units are designed
to specific input conditions, and allow for single
and multiple orifice configurations.

Upon compression of the rate control,
the compression check ball seats. As the piston head
moves, oil is forced through the orifice hole(s) located
in the shock tube, producing the required damping force.
After the oil has passed through the orifice hole(s),
a portion of the oil passes through the extension check
valve and fills the rod end of the shock tube. The remainder
of the oil volume displaced by the piston rod compresses
the foam accumulator.

Upon extension of the rate control,
the extension check ball seats. As the piston head moves,
oil is forced through the orifice hole(s) located in
the shock tube producing the required damping force.
The compression check ball is unseated by the flow of
oil that fills the blind end of the shock tube.Enidine
Incorporated's DA Series models can be custom orificed
to provide increasing resisting force over the stroke
through the use of multiple orifices in the shock tube.
This can be beneficial when controlling the velocity
of a lid as it closes, since the torque from the weight
of the lid changes as it closes.
