Pneumatic system for an internal combustion engine

Abstract

The invention relates to a system (100) for operating a valve of an internal combustion engine (10), said system comprising a primary fluid circuit (60) configured to define a fluid passageway for circulating a compressible fluid medium there through being operatively connectable to an actuator (92) of an actuated flow control valve (90, 95) of said internal combustion engine, thereby capable of delivering a valve opening force. The system further comprises: a secondary fluid circuit (80) configured to define a secondary fluid passageway for transporting a compressed fluid medium, and having an inlet passage (87) connectable to a cylinder for receiving the compressed fluid medium; and an auxiliary pressurized system (81) comprising a chamber (83) and at least one reciprocating member (82) operable in said chamber (83), said auxiliary pressurized system (81) being arranged in fluid communication with said secondary fluid circuit (80) and in fluid communication with said primary fluid circuit such that said at least one reciprocating member (82) pressurizes said primary fluid circuit when said compressed fluid medium of the secondary fluid circuit acts on said at least one reciprocating member (82).
