| 摘要 |
<p>The invention refers to a variable displacement lubricant pump (10) for providing pressurized lubricant for an internal combustion engine (70), whereby a pump rotor with several slidable vanes (14) rotating in a shiftable control ring (12) is provided, the control ring (12) being actuated by a hydraulic control chamber (25) directly actuating the control ring (12), whereby a temperature control opening (26) is provided in a control chamber wall (27), a temperature control valve (30) is provided to connect or disconnect the temperature control opening (26) to atmospheric pressure, and the temperature control valve (30) is provided with a valve plunger (32) being axially shiftable and blocking or leaving open a fluid passage (39), and with a first bimetal actuator sheet (35; 42) directly actuating the valve plunger (32) and having a first switching temperature TS1 so that the valve plunger (32) is in its open position if the lubricant temperature T is above the first switching temperature TS1.</p> |
