ABSTRACT:
The fluid seals on the currently available piston assemblies are ineffective for blocking the leakage of electrical signals between the piston and the cylinder. The present invention utilizes an electrically conductive split ring seated in an annular groove in a piston and an electrically conductive annular spring disposed between the split ring and the piston to resiliently urge the split ring into conductive engagement with the hydraulic cylinder while providing continuous electrical contact between the split ring and the piston to block the leakage of electrical signals.
