摘要： A fuel tank arrangement for a tractor which stores its fuel in an auxiliary tank and a main tank that are spaced apart in the tractor. The tractor's engine receives its supply of fuel from a fuel pump after it has passed through a primary fuel filter. The fuel tank arrangement incorporates a first line fluidly connecting the main tank to the fuel pump. The arrangement also utilizes a main vent to connect the forwardmost portion of the upper section of the main tank to the atmosphere, and an auxiliary vent to connect the rearwardmost portion of the upper section of the auxiliary tank to the atmosphere. The next element of the arrangement is a supply system which requires all of the fuel to pass through the main tank to reach the fuel pump. The supply system fluidly connects the bottom section of the auxiliary tank with the forwardmost portion of the top section of the main tank through a second line. The second line includes a mechanism to pump fuel from the auxiliary tank to the main tank until the fuel in the main tank reaches a first predetermined volume. The second line also has a filtering element position between the pumping mechanism and the auxiliary tank to remove foreign matter from the fuel before it passes through the pumping mechanism. The last element of the arrangement is a dual purpose connector which is fluidly connected to the second line between the main tank and the pumping mechanism. This connector is also fluidly connected to the rearwardmost portion of the upper section of the auxiliary tank. In this position the connector vents the second line to the atmosphere when a vacuum occurs in the second line, while preventing the fuel flow from the pumping mechanism from entering the auxiliary tank.
摘要翻译：一种用于拖拉机的燃料箱装置，其将燃料储存在辅助箱中，并且在拖拉机中间隔开主油箱。拖拉机的发动机在通过主燃料过滤器之后从燃油泵接收燃料供应。燃料箱装置包括将主油箱流体地连接到燃料泵的第一管路。该装置还利用主通风口将主箱上部的最前部与大气连接起来，辅助通风口将辅助箱的上部的最后部分连接到大气。该装置的下一个要素是供应系统，其需要所有的燃料通过主罐以到达燃料泵。供应系统通过第二条流线将辅助油箱的底部与主油箱顶部的最前部分连接。第二行包括将燃料从辅助罐泵送到主油箱的机构，直到主油箱中的燃料达到第一预定体积。第二线还具有在泵送机构和辅助箱之间的过滤元件位置，以在其通过泵送机构之前从燃料中除去异物。该装置的最后一个要素是两用连接器，其流体地连接到主罐和泵送机构之间的第二管线。该连接器还流体地连接到辅助箱的上部的最后部分。在这个位置上，当在第二线中发生真空时，连接器将第二线路排放到大气中，同时防止来自泵送机构的燃料流进入辅助箱。
