ABSTRACT:
The invention proposes a hydraulic support element (1) whose high-pressure chamber (10) is kept substantially free of air bubbles and oil foam. This is realized through a deflecting sleeve (15a) in combination with two vent bores (16) situated diametrically opposite each other on the inner peripheral surface (17) of the pressure piston (5).
