摘要：
An electro hydraulically adjustable pump has an adjustment member which is adjustable by at least one adjustment piston, a control valve which acts upon the at least one adjusting piston, a servo amplifier which triggers the control valve and which is supplied with an actual value of a pump adjustment and an actual value of a control valve adjustment, and an element which produces an additional pulse-shape adjusting signal as a function of an angle of rotation of the pump so as to control the control valve through the servo amplifier by the additional pulse-shaped adjustment signal.
