Abstract
A pump for conveying a liquid has a housing and a shaft rotatably supported in the housing. An eccentric drive is arranged in the housing. At least one drive element is provided and is configured to be driven by the eccentric drive. The shaft is configured to adjust the eccentricity of the eccentric drive. The drive element is configured to be adjusted according to the eccentricity of the eccentric drive by a translatory movement in a direction transverse to the shaft.
