Definitions
- the invention relates to a coolant and / or lubricant delivery device with one that can be driven by a drive Pump for lubricating oil delivery or cooling water circulation in Internal combustion engines.
- the pump is for the lubricating oil delivery usually one integrated in the oil pan Gear pump while the water pump is on the outside of the Engine blocks is attached. Both pumps are driven each via one driven by the internal combustion engine Chain or a V-belt. So both pumps are permanently connected to the internal combustion engine thus during the operation of the internal combustion engine continuously driven what a corresponding Energy expenditure required.
- the object of the invention is therefore the lubrication and / or cooling water circulation in internal combustion engines to make it more energy-efficient.
- This object is achieved in that the An electric motor is driven by a sensing element Generating a controlled variable in the internal combustion engine is provided and that the electric motor is dependent can be controlled by the controlled variable by means of a control.
- pumps of this type can thus be used either temporarily shut down or only operated as such be that with correspondingly reduced performance work to predetermined operating parameters, such as cooling water temperature or a minimum oil throughput.
- predetermined operating parameters such as cooling water temperature or a minimum oil throughput.
- It is preferably used as a pump drive motor low-voltage DC motor, especially a 12th Volts or a 24 volt motor use.
- the sensor is on Temperature sensor, the temperature changes due to friction determined and temperature-dependent signatures to the Control device transmitted.
- Such sensors are especially in the area of critical storage areas, e.g. Crank bearing shells, cylinder liners or the like intended.
- the pump intended for cooling or lubrication is designed as a vane pump, can by Actuator for regulating the liquid to be pumped too the angular position or the height of the pump blades can be changed his.
