Description

Reservoir with built-in pump, for liquid fuel stove Domestic heating by liquid fuel stoves is becoming more and more essential; it became necessary to remedy certain inconveniences resulting in particular from the fuel loading of these stoves.

One could indeed observe the inconvenience of transferring the liquid into a portable container, more or less well suited to the opening of the reservoir and of filling this reservoir several times a day.

In addition to the fact that handling the full containers could be troublesome for the housewives, it was added that, very save, a few drops of fuel oil fell nearby, dirtying the stove or the apartment, but also spreading an unpleasant odor.

The object of the present invention is to provide a reservoir with an incorporated pump, for a liquid fuel stove, which brings considerable advantages to the users and overcomes the disadvantages mentioned above, and which is intended especially for home use.

This reservoir comprises a casing having, on the top, an opening allowing the introduction of a pump fixed under a plate, which closes said opening after the installation of the pump inside the casing, characterized by the fact that the pump is arranged in the casing so as to be submerged in the liquid fuel and comprises a removable operating lever capable of being actuated from outside the casing.

The shape and capacity of this tank can be adapted to each stove model.

The appended drawings represent schematically, and by way of example, one embodiment of the object of the invention. fig. 1 is a perspective view of a parallelepipedic tank 1 with the front face open to show the pump located within the tank shell.

This pump is fixed to a Plate 2 closing off an opening for passage of the pump, located on the top, this removable Plate being fixed by screws.

The pump comprises a suction (or supply) pipe 3, bent at the top to be connected with a liquid fuel inlet pipe and which, on the other side, descends vertically into the casing of the tank. hope. This pipe is integral with two pump bodies 4, with which it communicates via the base; it is traversed by RTI ID="0001.0271" WI="4" HE="4" LX="1759" LY="1713"> an axis 5 of round section, which supports a balance beam 6 Door by the end of the axis 5 which pivots in a sealed bearing 5a, balance on which are embdt6es the rods 7 of the pistons B.

A sleeve 9 is welded to the rocker arm 6, just opposite the axle 5. This sleeve is intended to receive a removable maneuvering lever 10, which is introduced when it is ready, through a slot 11. In order to avoid the 6manations of fuel oil, this light 11 is normally closed & by a small Plate 12 folding down.

It is therefore sufficient to maneuver the lever 10 from right to left (and vice versa) to cause the alternating movement of the balance 6 and the pistons B.

The pump therefore operates at two times, in a continuous manner, since its Body is double. A level gauge 13, of a known model, indicates the end of the filling operation; an removes the first lavier 10 and an folds the Plate 12 once this Operation is completed. fig. 2 shows, sectional view at the level of the axis 5, the articulation of the balance wheel 6 and the position of the sleeve 9.

fig. 3 is a cross-sectional view, showing, from one side only, the detail of the pump supply (the two sides being similar). It is obvious that the tube 3 could be slightly offset, in order to allow the two pump bodies to be brought closer together, if the shape of the reservoir required it.

The liquid arriving via pipe 3 (direction of the arrows) enters via the base of this pipe into the pump body 4, passes through a valve 14, then a bucket 15, passes over the piston 8 and enters the reservoir.

We understand the advantage of the reservoir described, which lies both in the speed and in the ease of maneuvering, avoiding any movement, any carrying and any aging.

The reservoir described therefore forms a removable whole that adapts instantly, according to its shapes and dimensions, to all liquid fuel stoves.

It is obvious that the model of pump which has just been described could be replaced by any other model of pump with manual control, immersed, which can fulfill the same role.

Such a tank could, for example, supply several stoves.

Claims (3)

CLAIM Reservoir with built-in pump, for a liquid fuel stove, comprising a casing present on the top; an opening allowing the introduction of a pump fixed under a plate, which closes off said opening after the installation of the pump inside the casing, characterized in that the pump is arranged in the casing so as to be immersed in the liquid fuel and comprises a removable operating lever capable of being actuated from outside the casing. 1. Reservoir according to claim, characterized in that the pump comprises two pump bodies, integral with a suction pipe intended to be connected to a supply pipe and with which these pump bodies communicate by the base. 2. Tank according to claim and sub-claim 1, characterized in that the suction pipe is traversed by an axis arranged in a sealed bearing and integral with a rocker arm and a sleeve intended to receive the lever of removable lever, and by the fact that the ends of the rocker arm support the rods of two pistons, the alternating movements of the rocker arm caused by the operation of the lever actuating the pistons so that the liquid entering through the base into the pump bodies is driven into the tank shell with each upward movement of a piston. 3. Tank according to claim and sub-claims 1 and 2, characterized in that the casing has a slot capable of being closed by a closing plate and through which the lever penetrates into the casing when it is introduced into the sleeve, this opening being of sufficient length to allow the to-and-fro movement of the lever.
