摘要： A hydraulic control system for a gas exchange valve (18) of an internal combustion engine comprises a hydraulic actuator (40) associated with the gas exchange valve (18). A hydraulic pump (50) provides a hydraulic energy supply for the hydraulic actuator (40). A first control valve (100) controls hydraulic energy supply to the hydraulic actuator (40). A mechanical energy accumulator (80) is connected between cam means (72) and the hydraulic pump (50). The cam means (72) is capable of periodically storing mechanical energy into the mechanical energy accumulator (80) and of periodically causing its discharge. The mechanical energy accumulator (80) is capable of restoring mechanical energy that is stored therein to the hydraulic pump (50), for producing the hydraulic energy required for controlling the hydraulic actuator (40).
