Portable liquid measuring and dispensing device

摘要

Portable liquid measuring and dispensing device comprising a main reservoir for containing oil and to which a chamber is connected for metering a predetermined quantity of oil, this chamber being solid with the main reservoir and having a visual indicator showing the quantity of liquid contained in the chamber. The device includes a liquid moving assembly solid with the reservoir and the chamber, this assembly being formed of a rotary pump brought into rotation by a D.C. motor connected to a power source including a polarity inverter switch having a pair of buttons, each actuatable to cause rotation of the pump in one of its two directions of rotation. A piping installation operatively connects the reservoir, the pump, the chamber and the dispenser to allow movement of the liquid restrictively from the reservoir through the pump to the chamber when one of the buttons is actuated and the pump rotates in one of the directions, and to allow movement of the liquid restrictively from the chamber through the pump to the dispenser when the other one of the buttons is actuated and the pump rotates in the other direction.
