Patent ID: 10344648

Abstract:
A pump for conveying liquid includes a pump housing with an inlet and an outlet. An eccentric mounted at the housing rotates about an axis relative to the housing. A deformable element is disposed between the housing and the eccentric. A delivery duct from the inlet to the outlet is formed by the deformable element and a circumferential housing surface. The deformable element is pressed in sections against the housing by the eccentric to form a displaceable seal of the delivery duct and a closed pump volume in the delivery duct, which can be displaced along the delivery duct from the inlet to the outlet by a movement of the eccentric to convey liquid. A channel cross-section of the delivery duct is limited by the circumferential surface, a set-back duct surface of the deformable element and a contact seal between the circumferential surface and the deformable element.
