摘要： An electric pump drive motor three-phase stator assembly (1) includes three sets of stator segments (Si,j), configured in a ring about a stator axis (R). Each set includes n≥2 stator segments arranged in an n-fold rotational symmetry about the stator axis. Each stator segment includes a coil (3) having a first coil wire end and a second coil wire end. A plurality of 3n−3 connection wires (Wi,k) connect coils of a respective set of stator segments in series. A first and a second interposed stator segment are arranged in circumferential direction between the two connected coils of the respective set of stator segments. 3n−5 of the connection wires span across the first interposed stator segment at a distance (r1) to the stator axis and across the second interposed stator segment at a second distance (r2) to the stator axis (R). The second distance is larger than the first distance.

摘要： A valve system (13), connectable to a pump system (1), includes a pump assembly (3) connectable to a pipe (5), wherein the valve system (13) includes a valve (15) including a pipe section (39), of the pipe (5), that defines a primary flow direction (19), and a valve opening (41) in the pipe section, a valve seat (43) and a valve body (45). The valve opening (41), the valve seat (43) and the valve body (45) define a common valve axis (47) extending transversely to the primary flow direction. An operating element (49), arranged at the pipe section opposite the valve opening, is configured to control the valve body for operating in a check-valve mode to open the valve opening upon a fluid flow from the valve opening towards the valve body and for operating in a shut off-valve to close the valve opening for any fluid flow direction.
