摘要： [PROBLEMS] To solve the problems of a conventional pressurizing centrifugal pump that an inner peripheral wall, the edge of an outlet, blades, etc. are damaged when a foreign substance is included into a subject fluid and that intense cavitation and a big noise such as a draining sound occurring at the tips of the blades and lowering of pump performance are caused by moving of the fluid through a small gap between the inner peripheral wall and the tips of the blades. [MEANS FOR SOLVING PROBLEMS] In the pressurizing centrifugal pump, the tip of a blade (12) is formed to be low by providing a level difference (36) in the direction of the center from the outer periphery of a blade plate (14) to make the outer periphery of the blade plate (14) close to the inner peripheral wall (11) of a case (4) to form a fluid control space (h) for controlling moving of the fluid to the rear side of the blade and to form a fluid passage space (H) accelerating the passage of the foreign substance (X) included in the fluid between the inner peripheral wall (11) and the tip of the blade (12).

摘要： The invention relates to a delivery pump that is configured as a side channel pump. In said pump, a running wheel (2) is held on a shaft (3) in such a way that it can pivot in a limited manner about an axis that runs transversally to the shaft (3). This allows the running wheel (2) to adapt to the tolerances of a housing (1), thus preventing the running wheel (2) from abrading on the housing (1). The noise level of the delivery pump is therefore negligible.

摘要： Fuel pump (10) may comprise a casing (18) and a substantially disc-shaped impeller (20) which is rotatably disposed within the casing (18). A first group of concavities (21a) may be formed in a lower face of the impeller (20). A second group of concavities (20a) may be formed in an upper face of the impeller (20). A first groove (30) may be formed in the inner face of the casing (18) opposite the upper face of the impeller (20). The first groove (30) is formed in a region opposite the first group of concavities (21a) and extending from an upstream end to a downstream end. A second groove (24) may be formed in the inner face of the casing opposite the lower face of the impeller (20). The second groove (24) is formed in a region opposite the second group of concavities (20a) and extending from an upstream end to a downstream end. Preferably, the depth of the first and second groups of concavities and the depth of the first and second grooves are adjusted such that the flow of fuel flowing through the first group of concavities (21a) and the first groove (30) is greater than the flow of fuel flowing through the second group of concavities (20a) and the second groove (24).

摘要： A fuel pump has a housing (18) defining a cavity (28). A rotor (32) of an electric motor (30) is carried in the cavity (28) for rotation about a drive axis (37). An annular pump impeller (34) is supported in the cavity (28) separate from the rotor (32) and is driven by the rotor (32) for rotation about the drive axis (37).
