Pump

Abstract

Abstract PURPOSE: To pump out a liquid fuel at a fixed quantity and stop automatically by a method wherein a slender pipe along a suction pipe is dropped by a necessary size according to a scale, and the air in a container is allowed to flow in only from a lower end of the slender pipe when the liquid level has dropped in a pump with which to subdivide the liquid fuel for stove. CONSTITUTION: One or more hard slender pipes 10a, 10b different in length which are arranged along a suction pipe 5 are connected at the top or around into a pumping unit A provided with a discharge hose 3 on its top and having the suction pipe 5 connected at the bottom, which are slidable airthightly to move ventically, and an upper end projecting from the pumping unit A is closed to form a knob 11. A small hole 13 is then formed in a wall 1 in the middle of these slender pipes 10a, 10b, and a scale 14 for liquid quantity to suck is given upwardly from the small hole 13. The small hole 13 can be closed with a through hole wall 12 below the pumping unit A at a position where the knob 11 comes in contact with the pumping unit A. COPYRIGHT: (C)1981,JPO&Japio
