摘要： A two-stage gear pump has a pump section. The pump section has an internal space (51,52) that is located adjacent to a driven gear and about a cylindrical surface of the driven shaft. A discharge section of a first gear train is connected to a suction section of a second gear train with a communication passage (43). The internal space is connected to the communication passage with a pressure introduction passage (67,72). The pressure of the communication passage is introduced to the internal space by the pressure introduction passage, so that the pressure atmosphere of the internal space is an intermediate pressure atmosphere of the suction pressure and the discharge pressure of the pump section.

摘要： A fuel supplying system includes a tank (11) and a pump unit (12), which transfers fluid from the tank (11). The pump unit (12) includes a first pump (P1), a second pump (P2), and a drive source (M) . The first pump (P1) and the second pump (P2) are driven by the common drive source (M). The first pump (P1), the second pump (P2), and the drive source (M) are structured as one unit. This reduces the size and simplifies the structure of the fuel supplying system.

摘要： A variable displacement type gear pump has gear chambers, one of which is a specific gear chamber. A suction passage (35,36,37) is formed in the housing so as to communicate with suction-side spaces (31,33). An outlet passage (41) communicates with discharge-side spaces (32,34). A return passage (50) returns the fluid discharged to the discharge-side space of the specific gear chamber to the suction passage. The return passage communicates with the suction passage at a confluence portion located upstream side of the suction-side space. An opening and closing valve (51) opens the return passage in a small displacement operational state. A check valve (45) is located between the discharge-side space of the specific gear chamber and the outlet passage for preventing the fluid discharged from the gear chamber other than the specific gear chamber from flowing into the discharge-side space of the specific gear chamber in the small displacement operational state.
摘要翻译：可变排量式齿轮泵具有齿轮室，其中之一是特定齿轮室。吸入通道（35,36,37）形成在壳体中，以与吸入侧空间（31,33）连通。出口通道（41）与排出侧空间（32,34）连通。返回通道（50）将排出到特定齿轮室的排出侧空间的流体返回到吸入通道。返回通道在位于吸入侧空间上游侧的汇合部分处与吸入通道连通。打开和关闭阀（51）在小排量操作状态下打开返回通道。止回阀（45）位于特定齿轮室的排出侧空间和出口通道之间，用于防止从特定齿轮室以外的齿轮室排出的流体流入特定齿轮的排出侧空间室位于小排量运行状态。

摘要： A pump exerts pressure on fluid that has higher saturation pressure than atmospheric pressure at room temperature in a fluid reserving chamber in a fluid tank. The pump is located near the fluid tank. The pump has a housing and a heat generating mechanism. The housing defines a pump chamber, a motor chamber and a communication passage between the pump chamber and the motor chamber and includes at least one introducing port for introducing the fluid from the fluid reserving chamber into the housing and a bleeding port located above the introducing port for returning the fluid from the housing to the fluid reserving chamber. The heat generating mechanism is located in the housing. The fluid circulates into the housing through the introducing port and out of the housing through the bleeding port for substantially reducing the temperature in the housing.

摘要： A multistage gear pump for pressurizing fluid includes a housing, a drive shaft and a gear assembly. The drive shaft is rotatably supported in the housing. The gear assembly is disposed in the housing. The gear assembly includes at least first and second gear trains. Each train has a pair of drive and driven gears that are engaged with each other. The drive gear is provided on the drive shaft and followed by the driven gear. The first gear train and the second gear train are arranged so that fluid sequentially passes therethrough as the drive shaft rotates. A theoretical discharge capacity of the first gear train is larger than that of the second gear train.
