c. GRUNWALD. PUMPING APPARATUS. APPLICATION FILED. APR. I8. l9!!- Patented June 27,1916.
' through an overflow.

cans GRUN'WALD, or BREDENEY, GERMANY.
PUMFING- APPARATUS.
T 0 all whom it may concern Be it known that I, CARL GRUXWALD, a. subject of the Emperor of Germany, and residing at 116 Essenerstrasse, Bredeney, Germany, have invented certain new and useful Improvements in Pui'nping Apparatus, of which the following is a specification. x
This invention relates to that class of fuel pumping apparatus for internal combustion engines in which a constant quantity of fuel, corresponding to the maximum requirement of the fuel pump, is conveyed continuously by means of a special supplying pump to the suction chamber of the fuel pinup, and the fuel supplied in excess flows away again. Hitherto it has only been possible to'carry out this method of fuel supply, when the highest level of the fuel in the storage reservoir lay lower than the point of overflow in the suction chamber of the fuel pump.
' ow the object of this invention is to pro vide a fuel pumping apparatus which shall enable the aforesaid method of supplying the fuel to be carried out in any position of the storage reservoir.
- A constructional example of the invention is shown in the-drawing, in Which Figure 1 shows diagrammatically partly in section and partly in elevation, those parts of a. fuel pumping apparatus constructed according to this invention and with which this invention deals, and Fig. 2 shows in a sectional view and to a larger scale the special arrangement of a detail.
A is the cylinder of an internal combuslion engine into which the fuel is sprayed, the fuel valve 11 of which communicates with the fuel pump B, of well known construction, through the pipe C.
D is the compressed air vessel for the air for spraying in the fuel.
The suction chamber 1) of the fuel pump communicates through a fuel supply pipe. in X i-iii a supplying pump F, which is constructed in the form of a rotary or fan pump and the supply pipe G of which is connected to a chamber 71 of an overflow ieservoir H. The suction chamber 7) of the fuel pump B is a so directly connected to the overflow reservoir H by an overflow pipe .i. The chamber 15, of the overflow reservoii H is connected by means of a supply pipe K, to the fuel storage reservoir L.
Specification of Letters Patent.
Patented June 27, 1916.
Application filed April 18, 1911. Serial No. 621,963.
In the overflow reservoir H is arranged a. float M, 'see Fig. 2, which is positively connected by a two-armed lever N to the spindle 0 of a double acting valve. The valve disk of this valve which is located in the chamber h rests upon the mouth 1: of the pipe K, which is made in the form of a valve seat, when the floatM is in its highest position. \Vhen the float M is in its lowest position the valve disk 0 closes, with the upper surface of its disk, the passage it? between the chamber h and the reservoir H the lower end of the passage h? being formed with a valve seat.
In the description of the action of the apparatus, it'will be assumed that the overflow reservoir H is empty. Under-these circumstances the float assumes, under the action of its own weight, its lowest position, while the valve 0 0 assumes its highest position in which it lies against its upper seat 71 When the supplying pump F is set in operation itv draws continuousl a constant quantity of fuel, corre'spon ing to the maximum requirement of the 091 .pump B, from the storage reservoir L through the pipe K, chamber h and pipe G, and forces it through the pipe E'to the suction chamber 79 of the fuel jimp B, the suction valve 12 of which is acted on by the governor of the engine (not shown) in the usual way, for the purpose of regulating the supply of fuel to thefuel valve a to correspond to the load on the engine. When the fuel pump B driwsless fuel from its suction chamber 1) than the supplying pump F supplies thereto, the excess'of fuel flows through the overflow pipe J into the. overflow reservoir H. When the level of the fuel in the overflow reservoir H has reacheda certain height due to the continuously less consumption of fuel by the engine, the further supply of fuel through the pipe J the supplying pump now continues to take the 110 reservoir L and the overflowreservoir H, is
therefore automatically regulated by the double acting valve according to the level of the fuel in the overflowflreservoir-H.
The above described arrangement enables the fuel st orage reservoir L to be arranged at any desired pointyi. 6., higher than the fuel pump B or below it, or', as is shown in the drawing, to be so arranged that the level of the fuel in the storage reservoirmay be higher when the reservoir is full, and on the other hand lower as it gradually becomes empty, than the point of overflow in the suction chamber of the fuel pump.
I claim:
A 'fuel pumping apparatus for'internal combustion engines, comprising a fuel storage tank, an overflow reservoir, a supply pump running with a constant speed, a feed pump having a suction chamber, a fuel valve adjacent to the cylinder of the engine,
a source of compressed air communicating with said fuel valve and adapted to mix fuel and air and to spray the mixture into said cylinder; a feed pipe between the valve and the suction chamber, a supply pipe from said supply pump to the suction chamber, a supply pipe from said overflow reservoir to the supply pump, a supply pipe from said storage tank to the overflow reservoir, an overflow pipe ,from the suction chamber of the feed pump to said overflow reservoir and regulating means [for cutting off the supply from said storage tank, comprising a float in said overflow reservoir,
and a double acting supplvvalve actuated by said float and adapted to leave open one or the other or. both the outlet from the storage tank and the outlet from the over- 45 flow reservoir. 5
The foregoing specification signed at Barmen, Germany, this 31st day of March, 1911. a
