Patent ID: 8813705

Claim:
A hydraulic support element comprising: a housing, having a bore, a first bottom face, and a passage for a hydraulic means; a pressure piston, located within the bore and including, an interior jacket, a head projecting from the housing, a second bottom face, and an aperture in communication with the passage; a return valve; a reservoir directly in front of the return valve; a high pressure chamber, for the hydraulic means, extending between the first and second bottom faces, which can be sealed by the return valve; a deflecting sheath for the hydraulic means: which tightly contacts the interior jacket of the pressure piston axially below the aperture; which extends to the proximity of the head of the pressure piston; and, including: an edge furthest from the high pressure chamber; and, at least one perforation: connected to the edge; interrupting the edge; and, axially extending from the edge in a first direction, the first direction from the deflecting sheath toward the high pressure chamber; and, including a portion aligned with the aperture in a second direction orthogonal to the first direction; and, a rising line for the hydraulic means, formed between the deflecting sheath and the interior jacket, which starts at the aperture and extends in an area of the head into the reservoir, wherein high pressure can be provided from the reservoir via the hydraulic means.
