1. A device for controlling the lubrication of a work vehicle, which device includes:

  • a tank (1) for storing a lubricant (12);

    a number of delivery points (8a-g), at which lubricant is supplied to the tools of the work vehicle or other parts that need to be lubricated;

    a distribution block (5) including a number of branching points (6a-g) that are all connected to a delivery point (8a-g);

    a pump (2) for pumping lubricant from the tank (1) to the distribution block (5) and on to the delivery points (8a-g);

    a control system (3), for controlling the supply of lubricant,wherein the device also includes;

    a detector (4) that detects when a volume of lubricant that corresponds to a pump cycle is delivered from the pump and sends a signal with this information to the control system (3),a timer (11) that measures time intervals that correspond to a certain duration of time and is adjusted to, for each time interval, send a signal to the control system (3) that indicates that a time interval has elapsed, wherein the control system, based on the signals from the detector (4) and the timer (11), regulates the pump to deliver a certain number of pump cycles per time interval to the delivery points (8a-g).
