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 Pand a separation efficiency of at least 90% at a size P&#x3e;P; 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 P, where P&#x3c;P&#x3c;100 &#x3bc;m.

A phase setter for adjusting the rotational angular position of a cam shaft relative to a crankshaft of an internal combustion engine. The phase setter includes a stator; a rotor which together with the stator forms a first and second pressure chambers; a control valve featuring a pressure port, and first and second working ports; a feed for the inflow of pressure fluid to the pressure port, a first connecting channel connecting the first pressure chamber to the first working port, and a second connecting channel connecting the second pressure chamber to the second working port; and a reflux valve device acts in the feed and includes a valve structure extending annularly around the rotational axis and has one or more spring tongues or can be axially moved to restrict backflow of pressure fluid through the feed more significantly than the inflow of pressure fluid to the pressure port.

An oil pump for an internal combustion engine for drawing up the lubricating oil situated in an oil collector device has an oil pump housing wherein at least two pairs of gears are disposed. The pairs of gears, in order to form the pumping stages, are connected on the suction side to a suction passage formed in the oil pump housing and on the delivery side to a delivery passage. The oil pump housing is further formed with an oil supply passage that is connected to the suction passage of a first pumping stage and via which lubricating oil can be delivered to the suction side of the first pumping stage.
