Exemplary embodiments are directed to a hydraulic stored-energy spring mechanism for a high voltage circuit breaker. The spring mechanism includes a working cylinder situated in a working cylinder housing, at least one spring and at least one compression piston. The compression piston is slidably displaceable in a storage cylinder. The at least one storage spring pressurizes fluid located in the storage piston via the compression piston. The storage spring is held in a form-fitting manner by a support tube unit in the preloaded state.
