Definitions

  • the invention relates to a rotary pump with an adjustable delivery volume.
  • the rotary pump includes a pump housing with a low pressure inlet and a high pressure outlet.
  • a delivery rotor which can be rotated about an axis of rotation is arranged inside the pump housing.
  • the delivery rotor has a plurality of delivery means in order to deliver a fluid to be delivered from the low-pressure inlet to the high-pressure outlet.
  • the conveying means distributed over the circumference of the conveying rotor can in particular be radially movable in relation to the axis of rotation of the conveying rotor.
  • an adjusting element that can be moved in a translatory manner is arranged in the pump housing.
  • the actuating element preferably limits the movement of the conveying means radially outwards with an inner lateral surface.
  • control element is 10 in figure 4 shown in a plan view.
  • Figure 5 and Figure 6 show the in figure 4 marked sections of the actuating element 10.
  • the specific structure of the actuating element 10 reference is made to the above statements.
