Patentanspruch:Claim: Hydraulischer Wagenheber nach Patent 630 407, dadurch gekennzeichnet, daß der Kolbenkanal durch eine hinter der Druckfläche beginnende, in der Längsrichtung des Kolbens verlaufende AusnehmungHydraulic jack according to Patent 630 407, characterized in that the Piston channel through a longitudinal direction beginning behind the pressure surface of the piston extending recess (25) des Kolbens gebildet ist, welche bei tiefstem Kolbenstand eine Erweiterung(25) of the piston is formed, which is an extension at the lowest piston level (26) des Zylinders mit dem Ölbehälter (4) verbindet und so den Ölrücklauf ermöglicht. (26) of the cylinder connects to the oil tank (4) and thus enables the oil return. Hierzu 1 Blatt Zeichnungen1 sheet of drawings
