摘要： A fuel feed apparatus including a sub-tank is received in a fuel tank having multiple tank sections. Multiple jet pumps respectively transfers fuel received in the tank sections into the sub-tank. Therefore, even if a fuel amount received in a single tank section decreases, fuel can be steadily supplied from another tank section. Intermediately pressurized fuel in a fuel pump is supplied to the jet pumps, so that fuel can be steadily supplied to the jet pumps regardless of fuel consumption amount in an engine. Fuel is drawn from an upstream side of a pressure regulator, and supplied to the jet pump. The pressure regulator has an urging unit, and controls fuel pressure without using a diaphragm. Therefore, the pressure regulator is simplified and downsized.
摘要翻译：包括副罐的燃料供给装置被容纳在具有多个罐部的燃料箱中。多个喷射泵分别将在罐部分中接收的燃料转移到副罐中。因此，即使在单个箱部中接收到的燃料量减少，也可以从另一箱部稳定地供给燃料。燃料泵中的中间加压燃料被供应到喷射泵，使得燃料可以稳定地供应到喷射泵，而不管发动机中的燃料消耗量如何。燃料从压力调节器的上游侧抽出，供给到喷射泵。压力调节器具有推动单元，并且不使用隔膜来控制燃料压力。因此，压力调节器被简化和小型化。

摘要： A fuel pressure regulator for use in internal combustion engines. The fuel pressure regulator includes a valve seat and a vale body disposed downstream of the valve seat and is designed to move the valve body away from the valve seat through the pressure of fuel applied directly to the valve body. This eliminates the need for a diaphragm and results in a simplified structure of the fuel pressure regulator.
摘要翻译：用于内燃机的燃油压力调节器。燃料压力调节器包括阀座和设置在阀座下游的阀体，并且设计成通过直接施加到阀体的燃料的压力将阀体移动离开阀座。这样就不再需要隔膜并且导致燃油压力调节器的简化结构。
