摘要： The invention relates to an orbital pump for pumping a fluid, wherein the pump comprises at least one pump control system, a motor that can be controlled by the pump control system, a rotor shaft (10) for fluid transport, and a rotor sensor for detecting an absolute angle of rotation of the rotor shaft (40), the rotor sensor is connected to the pump control system and designed to transmit the angle of rotation of the rotor shaft (40) to the pump control system, and the pump control system is designed to rotationally control the rotor shaft (40) by means of the motor until the rotor shaft (40) is in a pre-determined angle of rotation position.

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： A pump device for pumping a liquid, has a hydraulics housing (12), in which a pump ring (14) with a contact surface (46), a pump ring support (16) and an eccentric (18), which can be driven by a shaft (20), are accommodated. The hydraulics housing (12) has an annular portion (22) and a first and a second lateral section (24, 26), the two lateral sections (24, 26) being arranged opposite each other. The pump ring (14) is mounted between the two lateral sections (24, 26) of the hydraulics housing (12) at least in some portions. The profile of the contact surface (46) has a contour with a curvature that changes at least in portions, and specifically in such a way that the curvature increases at least in some portions towards the ends of the contact surface (46).

摘要： The invention relates to a pump device for pumping a liquid having a hydraulics housing (12), in which a pump ring (14), a pump ring support (16), and an eccentric (18) are accommodated, which eccentric is to be driven by a shaft (20), which defines an axial and a radial direction, wherein the pump ring (14) has a first axial side (45) and a second axial side (47), wherein the hydraulics housing (12) comprises an annular portion (22) and a first and a second lateral section (24, 26), wherein the two lateral sections (24, 26) are arranged opposite each other, wherein the pump ring (14) is arranged, at least in some portions, between the two lateral sections (24, 26) of the hydraulics housing (12), and wherein on the first axial side (45) and the second axial side (47), the profile of the pump ring (14) in each case follows a contour with an S-formed curve (32) with a convex section (34) and a concave section (36), wherein the convex section (34) lies further outwards in a radial direction of the shaft (20) in comparison with the concave section (36).

摘要： A motor housing (2) has a shaft section to receive a motor shaft (4) and a motor section to receive motor electronics (5) and motor windings (6). The shaft section and the motor section are separated from each other in a sealed manner by a separating pot (7) arranged in the motor housing (2). A metal ball bearing pot (8) with a ball bearing (9) is arranged in the separating pot. The ball bearing pot (8) lies indirectly against a motor housing section that is connected to the outer surroundings, via the separating pot (7). Thus, the motor housing functions as a cooling body. Accordingly, heat generated by the ball bearing (9) during operation is dissipated onto the motor housing and the outer surroundings, via the ball bearing pot (8) and the separating pot (7).

摘要： A pump device (10) for pumping a fluid, having a hydraulic enclosure (12) that comprises an annular section, a pump ring (14) that is deformable and which defines an annular pump chamber at least in certain regions, a pump ring carrier (16) that is solidly connected to the pump ring (14), a first connector and a second connector, which first connector and which second connector are in fluid communication with the pump chamber, wherein the pump device (10) is set up in such a way that at least one measure influences a parking position of an eccentric (18) such that said parking position is preferred in the region of a clamping member (114), the measure being selected from: a) at least one recess in the hydraulic housing, which recess locally widens the chamber for the pump ring (14) in the axial direction, b) a geometry of the pump ring carrier (16), in which the pump ring carrier (16) has an enlarged diameter on its inner side facing the eccentric (18) in the angular region of the clamping member (114), and c) a geometric configuration of the pump ring (14), which, in the non-installed state of the pump ring (14), provides in one region at least a reduced strength of the pump ring (14), said region being in the clamping member region in the installed state of the pump ring (14), resulting in a reduced axial pressing action of the pump ring (14) in the clamping member region.
