Stabilizer™ Hybrid Chamber Design

One of the most important design goal of pneumatic vibration isolator is to achieve lower natural frequency. It is related to the isolator's compliance volume - the larger the volume, the lower the frequency. Unlike the conventional design of a compliance chamber (the volume of which affects natural frequency) and a damping chamber, Newport's patented Stabilizer hybrid chamber design consists of a small size initial chamber and a second damping chamber together as a unified hybrid chamber. Because the initial chamber is reduced dramatically in size, it forces the isolator to use the second chamber as part of the compliance volume, which greatly increases the compliance volume for a given package size, and greatly lowers the natural frequency.
