Abstract
An arrangement for regulating supply flow and limiting supply pressure of an adjustable pump, has a flow regulating valve, a control spring and a throttling element for controlling the flow regulating valve and arranged so that a primary pressure takes place upstream and a secondary pressure takes place downstream of the throttling element so as to form a pressure differential, an adjusting member operative for adjusting the pump and controllable by the throttling element, a servo element operative for forming communication with a pressureless space in the event when the supply pressure exceeds a predetermined value so that the pump is adjusted back to a smaller supply, as second throttling element arranged to bring the secondary pressure to the flow regulating valve, and a third throttling element arranged to vary the secondary pressure, connected in series with the servo valve, and first operating when the latter is open.
