Abstract

Device for pressure regulation of a hydraulic pump for pumping a hydraulic medium under pressure, comprising delivery-quantity regulation; a piston unit including first biasing element; a piston member; a first surface on the piston member to be biased by a first biasing force of the hydraulic medium in a first direction; a second surface on the piston member engaged by the first biasing element to be biased by a second biasing force in a second direction, opposite to the first direction; second biasing element to bias the piston member in addition to the hydraulic medium and the first biasing element, thus influencing the pressure of the hydraulic medium.
