摘要： The invention relates to a pump device comprising an impeller (10a; 10c), which is mounted to rotate about a rotational axis (11a; 11b; 11c) in order to convey a pumpable medium, an inlet housing (12a), which opens out into a priming region (13a) upstream of the impeller (10a; 10c), and comprising a flow guiding element (14a; 14b), which is arranged at least partially inside the priming region (13a) and which is designed to guide the medium flowing towards the impeller (10a; 10c). According to the invention, the at least one flow guiding element (14a; 4b; 14c, 15c) is designed at least partially as an annular segment.

摘要： A fluid pump (10) includes an inlet (34) for introducing fluid into the fluid pump (10); an outlet (52) for discharging the fluid from the fluid pump (10); a motor (20) having an armature (54) which rotates about an axis (24) such that the armature (54) is supported at one end (46) by a first bearing (44) and at second end (90) by a second bearing (88), the motor (20) also having a stator (59) which circumferentially surrounds the armature (54) such that a fluid passage (65) is defined radially between the armature (54) and stator (59) through which the fluid flows from the inlet (34) to the outlet (52); a pumping arrangement (28) which is rotated by the armature (54) and which pumps the fluid from the inlet (34) to the outlet (52); a flow impedance member (98) extending axially in the fluid passage (65) which impedes circumferential flow of the fluid within the fluid passage (65), thereby generating a pressure gradient circumferentially within the fluid passage (65) which applies a lateral force (F L ) to the armature (54).

摘要： The invention relates to a turbine engine including two rotatable shafts (3, 4) and a lubrication unit comprising at least one pump (30) which comprises a casing (44) inside of which a rotor (42) is mounted and driven by one of said shafts, the pump casing being rotated by the other of said shafts such that the actuation of the pump depends on the difference between rotational speeds of the shafts, characterised in that the shafts are a drive shaft (3) and a fan shaft (4) respectively, the fan shaft being driven by the drive shaft by means of a reduction gear (10) which is lubricated by the lubrication unit, and in that the reduction gear is annular and the pump (30) passes axially therethrough.

摘要： The invention relates to a circulating pump, comprising a delivery element (40) for delivering a delivery liquid, and an electric motor (22) which has a stator (24) and a rotor (26), between which a gap (76) is formed, wherein the rotor comprises a shaft (36) which can be rotated about a rotational axis (38) and to which the delivery element is connected fixedly so as to rotate with it, and wherein the circulating pump has a radial plain bearing (52) for mounting the shaft, which radial plain bearing (52) is liquid-lubricated with the delivery liquid at a lubricating region (58). In order to provide a circulating pump of this type, by way of which more reliable operation is made possible, it is proposed according to the invention that the circulating pump comprises a sealing device (92) which suppresses a fluidic connection between the lubricating region and the gap between the stator and the rotor.
