Abstract (en)
[origin: WO2017085354A1] The pressure regulating arrangement for a lubricating system of a piston engine comprises a pressure regulating valve (16) for releasing pressure from a lubricating oil line (4), a first control valve (19), which is con- figured to open when a control pressure at the valve (19) exceeds a first predetermined limit value, and a second control valve (20), which is configured to open when a control pressure exceeds a second predetermined limit value, which is lower than the first predetermined limit value, wherein the opening of a control valve (19, 20) is configured to allow opening of the pressure regulating valve (16). The arrangement further comprises a control line (17) for transmitting control pressure from the lubricating oil line (4) to the first control valve (19) and an actively controllable valve (25) for opening and closing fluid communication be- tween the control line (17) and the second control valve (20).
