CONTROLLABLE COOLANT PUMP WITH A FILTER DISC, FILTER DISC, AND THE PRODUCTION THEREOF
In a controllable coolant pump for conveying a coolant for an internal combustion engine, a conveying stream of the coolant can be limited by way of a control slide (7) which is actuated by way of a hydraulic actuator (6) in a hydraulic control circuit (11), wherein the hydraulic control circuit (11) is fed with the coolant from the conveying stream, and comprises an axial piston pump (4) and a proportional valve (5) for generating and controlling a pressure to the hydraulic actuator (6). A sliding pad (42) which is arranged towards a suction side of the axial piston pump (4) surrounds an inlet of the axial piston pump (4), and a filter disc (24) for filtering the coolant before an inlet into the hydraulic control circuit (11) is in sliding contact with the sliding pad (42), with the result that coolant is sucked from the pump chamber (10) through the filter disc (24) and the sliding pad (42) into the axial piston pump (4) while a rotational movement of the filter disc (24) is transferred into a lifting movement of the axial piston pump (4). The filter disc (24) consists of a ceramic material.
The invention relates to a controllable lubricating oil delivery system (1) for an internal combustion engine (3), said delivery system having a screw spindle pump (2) for delivering lubricating oil with at least one screw spindle (22) which is rotatably accommodated in a spindle chamber (20), wherein the screw spindle pump (2) is arranged such that a suction side (21) of the spindle chamber (20) is connected to a suction path (11) from an oil sump (30) of the internal combustion engine (3), and a pressure side (23) of the spindle chamber (20) is connected to a feed path (13) to moving parts of the internal combustion engine (3). The lubricating oil delivery system (1) is characterised in particular in that: the screw spindle pump (2) is driven by the internal combustion engine (3); and a controllable throttle valve (4) is provided at the suction side (21) of the spindle chamber (20), by means of which a throughflow cross-section of the suction path (11) can be gradually limited between an open position and a closed position. Therefore, the oil pressure in an internal combustion engine (3) is adjusted initially by means of a suction throttling process in conjunction with a screw spindle pump.
