摘要： A centrifugal separator for separating oil, the centrifugal separator comprising a centrifuge housing, a drive housing, a separating rotor, a shaft, a first bearing, a second bearing and a drive. A drive chamber is formed in the drive housing and a separating chamber is formed in the centrifuge housing. A partition wall is formed between the drive chamber and the separating chamber, and the partition wall comprises an opening. The shaft extends through the opening of the partition wall into the separating chamber and into the drive chamber, and the separating rotor is connected to the shaft for conjoint rotation and is arranged in the separating chamber. The drive is arranged in the drive chamber and drives the shaft, and the drive is in the form of an electric motor which drives the shaft directly in such a way that the shaft forms a motor shaft of the electric motor.

摘要： The invention relates to a pump device for pumping a liquid, comprising a hydraulics housing (12, 212), in which a pump ring (14, 214), a pump ring support (16, 216) and an eccentric (18), which can be driven by a shaft (20), are accommodated. The hydraulics housing (12, 212) has an annular portion (22, 222) and a first and a second lateral section (24, 26, 224), the two lateral sections (24, 26,224) being arranged opposite each other. The pump ring (14, 214) is mounted between the two lateral sections (24, 26, 224) of the hydraulics housing (12, 212) at least in some portions. On a side facing away from the pump ring support (16, 216), two first projections (28, 228), which run in the axial direction of the shaft (20), are each in contact with one of the two lateral sections (24, 26, 224).

摘要： The invention relates to a pump device for pumping a fluid, comprising a hydraulic housing (2), a pump ring support (5) which is arranged in the hydraulic housing (2), an elastic pump ring (3) which is arranged between the pump ring support (5) and the hydraulic housing (2) in the radial direction (RR), and a separating chamber pin (4), wherein the pump ring (3) can be pressed in the radial direction (RR) against an inner wall surface of the hydraulic housing (2) by means of the separating chamber pin (4) in order to produce an at least local seal on the hydraulic housing (2), and wherein the hydraulic housing (2) has a radial offset section (6), along which an offset element that is formed on the separating chamber pin (4) or a separate offset element that interacts with the separating chamber pin can be introduced in the axial direction (AR) and thus offsets the separating chamber pin (4) and the pump ring (3) in the radial direction.
