Abstract
A regulatable pump, in particular a vane pump, is provided with a rotor, with a rotor body and with at least one guide ring and with a cam ring. The eccentricity of the cam ring can be adjusted by means of a regulating piston, a journal of the cam ring lying between a spring-pretensioning means and the regulating piston. At maximum eccentricity, the cam ring bears on the outside by means of a bearing part of its circumferential wall against a bearing surface on the inside of the housing.
