AIRPOT DASHPOTS, ACTUATORS, AND SHOCK ABSORBERS (SNUBBERS) Dashpots > Actuators > Օ Shock Absorbers >

The Airpot Dashpot is a motion damping devicethat reduces velocity, vibration, and oscillation in dynamic mechanisms. This is accomplished by using a piston to force ambient air through an orifice at a controlled rate to dissipate kinetic energy. > AIRPOT DASHPOTS, ACTUATORS, AND SHOCK ABSORBERS (SNUBBERS) It has unparalleled low friction,responds to forces as low as only a few grams, and its smooth. > Starting and running friction are almost identical, which prevents jerky, uncontrolled starts. > It prevents damage and violent or inaccurate response caused by shock and vibration in...

All Airpot damping devices are dashpots generically, but for ease of discussion, we identify configurations in which > reset the piston for the next cycle (see shock absorberillustration). the piston rod is attached to the load being damped as dashpots. Two Way Damping (Unit damps in both directions.) We identify configurations in which the piston rod is The ball joint rod connection contains no check valve and therefore does not allow air flow through the piston. This results in approximately equal resistance to motion (damp- ing) in both directions. Two way damping is generally...

continued 10 seconds, and so forth. All compu-tations must be scaled to accommodate the maximum force and stroke limita- tions of the dashpot model selected.When calculating the not the total available stroke.Please contact Airpots engineering department if youҒd like assistance. Can the applica-tion tolerate some gradual force buildup (as in the compression direction), or must the resisting force be immediate (as in the pull direction)? Rate of force rise in the Airpot damping unit requireddamping coefficient, > it is important toconsider the air spring characteristics of the model...

continued be a function of its diameter andlength. Check the rod buckling curves (below) to determine the best size rod, considering the forces and length being used in the application.If the dashpot is damping in thepull direction, the rods yield strength is the main consideration. All Airpot connecting rods are capa- ble of withstanding any load applied in the tensile direction which does not exceed the force of atmospheric pressure on the piston. dard with rod end ball or pin link joints.
