Patent ID: 10294937

Abstract:
A pump for conveying liquid includes a pump housing having an inlet, an outlet, an inner circumferential surface and a geometric axis. An eccentric in the housing is rotatable about the geometric axis relative to the housing. A deformable element is disposed between the inner circumferential housing surface and the eccentric. A delivery duct from the inlet to the outlet is formed by the deformable element and the inner circumferential housing surface. The deformable element is pressed against the housing by the eccentric in sections so that a displaceable seal of the duct and a closed pump volume in the duct are formed and are displaceable to convey the liquid along the duct from the inlet to the outlet by rotation of the eccentric. A receptacle, accommodating an edge region of the deformable element, is formed by the inner circumferential housing surface and a counter bracket.
