Telescopic auto-locking support for load - comprises chamber joined to reservoir of fluid by pipe equipped with interruption part movable between open, closed positions which allows communication

摘要

The support comprises a jack body (1) in which a piston (2) is mounted slidably and defines a chamber (3) of variable volume. One of the elements is fixed to the load and the other is also fixed. The chamber (3) is joined to a reservoir (5) of fluid by a pipe (4) equipped with an interruption part (7) movable between an open and closed position and when open establishes communication of the chamber (3) with the reservoir (5). The movable part overcomes two conflicting forces, in open and closed positions. USE/ADVANTAGE - Allows adjustment to keep load level. Load tables.
