A fuel supply device includes a pump unit with a fuel pump that has a rotary body rotating about a rotary shaft and a load receiving portion, configured to receive the load of the pump unit. A connecting portion is provided for connecting the pump unit to the load receiving portion such that the pump unit is suspended by the load receiving portion. The connecting portion is disposed so as to extend across a virtual plane which is perpendicular to the rotary shaft for the rotary body of the fuel pump and passes through the center of gravity of the pump unit.

A non-occluding intravascular pump comprises a shroud providing an inlet for incoming blood flow and an outlet for outgoing blood flow, wherein the shroud is a cylindrical housing; an impeller positioned within shroud, wherein a central axis of the shroud and impeller are shared; a motor coupled to the impeller, wherein the motor rotates the impeller to causes blood to be drawn through the inlet and output to the outlet, and the motor is centrally disposed and shares the central axis with the shroud and the impeller; and a plurality of pillars coupling the motor to the shroud, wherein the pillars secure the shroud in close proximity to the impeller. Various design features of the pump may be optimized to reduce hemolysis, such as, but not limited to, inlet length, impeller design, pillar angle, and outlet design.

A fan assembly comprises a fan and a movable fan support. The fan has a motor and a fan blade drivable by the motor to move air in an airflow direction through an opening. The movable fan support is configured to movably support at least the fan. The fan support is mountable adjacent the opening on a first side and comprises extension members extendable from an operating position on the first side of the opening to an access position on a second side of the opening opposite the first side. In the access position, the extension members extend through the opening from the first side to the second side to support the motor and fan blade on the second of the opening for access.

An apparatus for cleaning nets underwater formed from a propeller housing with a centrally disposed axis with a plurality of blades extending therefrom. An outer perimeter ring secured to an outer tip of each blade with a plurality of knuckles secured to the outer perimeter ring. Each knuckle including a curved surface constructed and arranged to be forcefully presented to the aquaculture net upon rotation of said blades for removal of growth by impact and shaking of the aquaculture net. An elastomeric hub prevents spike loads.

Example implementations relate to a method and system for pumping fluid with a pump assembly to cool waste-heat producing system of an apparatus. The pump assembly includes a first housing, a rotor assembly, a stator assembly, a second housing, an outlet connection port coupled to the second housing, and a guide vane insert. The first housing includes a first bore and first inlet guide vanes (IGVs) coupled to inlet of the first bore. The rotor assembly including an impeller, is disposed in the first bore. The stator assembly including a coil, is mounted around a portion of the first housing. The second housing has a second bore fluidically coupled to the first bore, and first outlet guide vanes (OGVs) coupled at an entrance of the second bore. The guide vane insert including second OGVs, is disposed within the outlet connection port and fluidically coupled to outlet of the second bore.

A pump assembly can pump fluid with a single moving part, where the single moving part is free floating, inline within a sealed fluid path. The pump includes a stator core having a cylindrical shape with an opening through it. The stator includes electromagnetic coils arranged around a lateral surface of the stator core extending away from the center of the stator core. The pump assembly includes an impeller to spin within the cylindrical opening of the stator in response to selective charging of the electromagnetic coils. The impeller includes a cylindrical body having blades that align with the electromagnetic coils to create a magnetic flux path between selected coils through the impeller in response to selective charging of the electromagnetic coils.

Blood pump assemblies and methods of manufacturing and operating blood pump assemblies are provided. The blood pump assembly includes a pump and an impeller blade rotatably coupled to the pump. The blood pump assembly also includes a pump housing component sized for passage through a body lumen and coupled to the pump. The pump housing component includes a peripheral wall extending about a rotation axis of the impeller blade. The peripheral wall includes an inner peripheral wall surface and an outer peripheral wall surface. The peripheral wall also includes one or more blood exhaust apertures. Each blood exhaust aperture in the one or more blood exhaust apertures is defined by an inner aperture edge and an outer aperture edge. Each inner aperture edge is chamfered between the inner peripheral wall surface and the outer peripheral wall surface.

The catheter device comprises a drive shaft connected to a motor, and a rotor mounted on the drive shaft at the distal end section. The rotor has a frame structure which is formed by a screw-like boundary frame and rotor struts extending radially inwards from the boundary frame. The rotor struts are fastened to the drive shaft by their ends opposite the boundary frame. Between the boundary frame and the drive shaft extends an elastic covering. The frame structure is made of an elastic material such that, after forced compression, the rotor unfolds automatically.
