Self Centering Dampers

AVM offers a unique, patented product that allows controlled movement in extension and compression and provides a controlled rate of return from either direction to a neutral position.

The most common use for this new technology is in the control of hydrostatic transmissions. The Self-centering damper replaces a combination of springs and dampers with a single, compact, cost-effective unit. The Self-centering damper is linked to a control lever or pedal and provides a controlled rate of actuation as well as a return to a positive neutral position.

The unit may be mounted in any orientation and still provide smooth, consistent return to neutral.
