Patent ID: 10751730

Abstract:
A particle separating system for supplying a cam shaft phase adjuster with cleaned lubricating oil. The phase adjuster includes a stator, a rotor connectable to a cam shaft, and a control valve for hydraulically adjusting the rotational angular position of the rotor relative to the stator. The particle separating system includes an oil separator arranged in the flow of the lubricating oil, upstream of an oil gallery of an engine supplied with the lubricating oil, exhibiting a separation efficiency of at least 50% for particles having a size P1 and a separation efficiency of at least 90% at a size P2>P1; a particle separator arranged downstream of the oil separator and upstream of the phase adjuster or control valve, to clean the lubricating oil for the phase adjuster. The particle separator exhibits a separation efficiency of 50% at a size P3, where P1<P3<100 μm.
