Abstract
A zone block assembly for maintaining a pressure barrier in an end area of a rotor in an electrodynamic system such as an electrical generator includes a zone block which is constructed and arranged to be positioned between a rotor and an end winding in an electrodynamic system to maintain a pressure barrier; and a spring in contact with the zone block for biasing the zone block with respect to the rotor. The spring is fabricated from a material which is non-metallic, so that it will not create destructive metallic projectiles within the electrodynamic system if it breaks as a result of fatigue.
