ABSTRACT:
A vibration damping device for a thermostatic expansion valve comprises a spring member having a plurality of cantilevered fingers substantially parallel to the direction of travel of moving components but which are spring loaded to provide a force normal to that direction. The damping device is fixedly attached to one of the moving or stationary components and is arranged so that its fingers exert the normal force against the other of the moving or stationary components. Accordingly, a constant magnitude frictional force is produced over the range of movement, thus damping vibrations caused by pressure pulses from the compressor of the refrigeration system in which the thermostatic expansion valve is installed.
