Abstract (en)

[origin: EP1114918A2] The gas change system for an internal combustion motor, such as a diesel motor, has a hydraulically operated gas change valve (20) linked to an initial fluid system (30) for a medium to operate the valve (20). A second fluid system (40) for a hydraulic medium has a main control valve (50) to control the gas change valve (20). A medium separator (70) is between the main control valve (50) and the gas change valve (20), where one side is linked to the initial fluid system (30) and the other side is connected to the second fluid system (40). The main control valve (50) has a control piston (56), which sets the opening and closing of the gas change valve (20). The second fluid system (40) has an electromagnetic pilot valve (60) to act on the main control valve (50).
