<p>The hydropump, and especially a gear pump, has a pressure chamber (1), a suction chamber (2), and at least one displacement component (3) which is driven to switch between the pressure chamber and suction chamber so that hydraulic medium is pumped from the suction chamber into the pressure chamber. From the pressure chamber which is shut-off pressure tight in relation to the suction chamber, a backflow connection (4) carrying hydraulic medium, provided preferably in the pressure build-up section and with a predetermined flow passage, leads to the suction chamber.</p> |
