Abstract (en)
An automatic device for topping up the liquid in a container (C), particularly for topping up lubricating oil in the sump of an internal combustion engine, includes a sensor cylinder (10), an actuator cylinder (24), and programmed operating means (42, 48, 44) for moving the pistons (14, 22) of the sensor and actuator cylinders (10, 24). The presence or absence of liquid in the chamber (12) of the sensor cylinder (10) prevents or enables the sliding of the pistons (14, 22) so that the piston (22) of the actuator cylinder (24) supplies to the container (C) a quantity of liquid which is correlated with the level of the liquid in the container (C). <IMAGE>
