A fuel accumulator for the fuel tank of petrol driven saws, garden tools or outboard engines which are likely to be tipped and temporarily starved of petrol consists of a porous stable material, preferably sintered polyethylene or bronze with a pore size of 70 microns in case of petrol, which encloses an inner cylinder from which the fuel is pumped to the engine. The fuel accumulator inside the fuel tank has an outer tubular casing (2) with a flat bottom (3) and an inner tubular wall (4), all made of porous material,pref. sintered polyethylene. The pore size should be chosen to suit the type of fuel, i.e. 70 microns for petrol, so that it acts as a self-sucking filter. A flat cover (5) divides an outer chamber (7) from the inner chamber (8) which is joined by a hose on the nipple (6) to the engine. A cylindrical weight (9) e.g. a rolled-up metal strip, holds the accumulator at the fuel tank bottom. A vent hole (10) of e.g. 0.8 mm dia. ensures a rapid filling. |
