Flow channeling structure

A rotary pump for delivering a fluid, the rotary pump comprising:

• (a) a pump housing having a low-pressure inlet and a high-pressure outlet for the fluid to be delivered;
• and
• (b) a delivery rotor arranged such that it is rotatable about a rotational axis in the pump housing and comprising
• (c) multiple delivery means which are distributed over the circumference of the delivery rotor for delivering the fluid from the low-pressure inlet to the high-pressure outlet, wherein
• (d) when the delivery rotor rotates, the radial and axial outer edges of the delivery means define a delivery region of the rotary pump, and
• (e) the rotary pump comprises a flow channeling structure which protrudes axially into the low-pressure inlet in relation to the rotational axis and is designed to influence the fluid flowing in the low-pressure inlet, wherein
• (f) the flow channeling structure is arranged along an axial region which does not overlap with an axial extent of the delivery region and is arranged along a radial region which overlaps with a radial extent of the delivery region, wherein
• (g) the flow channeling structure comprises an incident flow edge which is spaced apart from the delivery region in the radial direction and arranged substantially parallel to the rotational axis, such that the fluid flowing in the low-pressure inlet flows onto the incident flow edge from a radial and/or tangential direction in relation to the rotational axis.
