Claims (3)

Patent specification 274 113) has for the division of the patent claims: capacity to at least two containers, which to secure the desired slope in a higher 1. Arrangement for receiving and distributing the stored operating container and one or more Divide the fuel supply on tractors, especially 5 lower storage containers. The latter is Agricultural tractors, with two separate fuel tanks with the operating tank through a line, each of which has a separate delivery, into which a three-way valve and a hand pump Approach line with one each of the reflux is built into it. In addition, the storage container is through Tank blocking, arranged in a common block a direct overflow with the operating tank Non-return valve tied to the only Mo- io so that when the storage container is filled, suction line is connected, causing liquid to flow through the overflow into the operating tank characterized in that the two power rises. With this known arrangement, a Substance tanks (5 and 6) in a known manner in overflow of the tank not avoided with certainty at different heights on the vehicle (1). are arranged and the block (11) a compensation 15 Finally, it is also already known and contains extraction chamber (18) to which the (British patent 827 765), three fuel tanks common suction line (16), a return line in series to be arranged, in each of which a submersible pump combined with an electric (10) of the fuel delivery system and the de-motor is installed. The ventilation line (17) of the lower-lying fuel pressure lines of two of the fuel tanks (S) are connected. 20 built pumps lead to a shuttle valve to which 2. Arrangement according to claim 1, characterized in that a pressure line is connected, which is shown in an alternation, that the two check valves (14 valve opens to which on the one hand the pressure line of the and 15) and the equalization and extraction chamber in the third tank built-in pump and other- (18) receiving block (11) deeper than the two sides of a pressure line leading to the carburetor-fuel tanks (5 and 6) is arranged. 25 is closed. Apart from the great construction effort 3. Arrangement according to claim 1 and 2, characterized here is a device to a characterized that only the supply lying power continuous fuel flow to the carburetor safety tank (5) to deliver a level indicator (20) regardless of whether the one is or is ordering. whose fuel tank is empty or not. 30 In the further known device (USA.- Patent specification 2 973 121), from which the invention is based, two fuel tanks are provided in the The invention relates to an arrangement for a pump is also installed, the pressure absorption and distribution of the fuel supply on lines lead to a reversing valve, which via tractors, in particular agricultural tractors, with 35 another pressure line with the carburetor in two separate fuel tanks, each of which is above bindui.g. Both tanks have a slight incline a separate extraction line, each with one opposite the associated pump, so that even when the tank is backflowing into the tank, the non-return valve, which blocks the engine and is located in a common different position of the vehicle, is still supplied with fuel.
only engine suction line is connected. 40 It is the object of the invention to provide an arrangement of To further develop a known fuel or lubricant tank, as described in more detail at the outset, (USA.-Patent 2 320 913) is through longitudinal and that an extremely good utilization of the Transverse walls divided into ten cells or chambers, space for the accommodation of the force in each chamber, namely close to the floor, results in a stock of material, without the space available for the Check valve is built in, which is deteriorated all via lines 45 drivers. At the same time, and further check valves built into this ensure that regardless of the inclination are connected to each other and with a standpipe. of the vehicle in relation to a horizontal plane The tank is hereby a reliable supply of fuel from the lockable Inlet filled from above, with the filling material opening through fuel tanks to the fuel feed pump poured into all chambers. It is taken from 5 ° is guaranteed. This object is according to the invention the tank content from the standpipe, at the lowest point of which has been solved by opening the two fuel tanks Place a pressure line leading to the engine, screwed on in a manner known per se at different heights is. For this arrangement, a relative support is arranged on the vehicle and the block one agile construction effort required. Contains compensation and removal chamber to which the It is also known (US Pat. No. 1,358,783), 55 common suction line, a return line of a motor vehicle with a main tank arranged behind the driver's seat and the vent line and a fuel tank located in front of the driver's seat connected to the lower seat Equip reserve tank, whereby are. In contrast to the latter described last, from the main tank via a line with a known device, a pre-installed shut-off valve is filled in this way and created over a direction in which, as a result of the non-return extraction line with a built-in shut-off valve with valves, the fuel return into a tank, when the one line leading to the carburetor is filled in connection with the other tank, is interrupted, with one standing. Same operation is made by the manual shut-off of the reserve when the fuel level tanks there is the danger that when there is insufficient as a result of a tank vehicle inclination to be higher control undesirable idling portfolios reserve _"5 comes as that of the other. If the level is equal, tanks can enter. an even emptying of both fuel tanks. Another device that has become known also allows the provided compensation and Liquid containers in vehicles (Swiss extraction chamber that the inflowed fuel from
