摘要： A regenerative fluid machine having guide vanes on a flow channel wall is disclosed. The regenerative fluid machine includes a circular plate-shaped impeller having a plurality of vanes radially formed on an outer circumference thereof at regular intervals, casings in which the impeller is housed, and flow channels, each of which has a suction hole and a discharge hole in opposite ends thereof, and which are circumferentially disposed within the casings so as to face the vanes. The plurality of guide vanes having an inclined angle (θ) with respect to a radial direction protrude from the flow channel wall in a rotational direction of the impeller so that a relative inflow angle (β) of the fluid introduced into the impeller grooves is increased and thus an absolute inflow angle (α) is decreased.

摘要： A fuel pump, including a driven impeller, which rotates in a pump housing and on the two sides comprises guide blades that each delimit a ring of blade chambers, and further including partial ring-shaped channels, which are arranged on both sides in the region of the guide blades in the pump housing and which form delivery chambers with the blade chambers for delivering fuel, wherein an inlet channel leads into the one delivery chamber and the other delivery chamber leads into an outlet channel, and mutually opposing blade chambers are connected to each other. The cross-sectional surface of the partial ring-shaped channel arranged on the inlet side decreases toward the end of the partial ring-shaped channel to zero. The region in which the cross-sectional surface decreases extends over an angular region of more than 45°.

摘要： The present invention provides a pump comprising a regenerative pumping mechanism having a generally disc-shaped rotor mounted on an axial shaft for rotation relative to a stator. The rotor has first and second surfaces each having a series of shaped recesses formed in concentric circles thereon, and a stator channel formed in a surface of the stator which faces one of the rotor's first or second surfaces. Each of the concentric circles is aligned with a portion of a stator channel so as to form a section of a gas flow path extending between an inlet and an outlet of the pump, and the rotor divides the section of flow path into sub-sections such that gas can flow towards the outlet simultaneously along any sub-section, channel or rotor side. As a result, the gas being pumped flows in a parallel fashion along both surfaces of the rotor. Thus, this configuration can provide a pumping mechanism where gas pressures on either side of the rotor can be substantially equal or balanced.

摘要： A pump has a main body. An assembling part is formed in the main body and has an assembling chamber. A mounting part is formed in the assembling chamber and has a discharging chamber. An influent hole and an effluent hole are respectively defined through an inner surface of the discharging chamber. A storage hole is defined through the assembling chamber and communicates with the effluent hole. A mounting cover is mounted on the mounting part. A motor is mounted on the main body. An impeller is located in the discharging chamber and connected with the motor. A covering assembly is mounted on the assembling part and has a storage chamber that communicates with the storage hole. When working fluid passes through the effluent hole, some of the working fluid enters the storage chamber via the storage hole, eliminating the need to additionally process the mounting cover.

摘要： In a pressurizing centrifugal pump, tips of blades are arranged at a level lower than that of an outer circumferential surface of a blade plate by a level difference provided from the outer circumferential surface toward a central position of the blade plate. The outer circumferential surface of the blade plate is arranged close to an inner circumferential wall of a case to form a fluid control space for controlling movement of the fluid toward a rear side of the blades. A fluid passage space for promoting passage of a foreign substance in the fluid is formed between the inner circumferential wall and the tips of the blades.
