Abstract (en)
1. Ram, particularly micro-ram, comprising a substantially cylindrical, hollow body (4) in which is movably mounted a piston (5) dividing the internal space of the said body (4) into two chambers of variable volume (6, 7) each of them being provided with a port (8) for fluid supply or fluid exhaust of the chamber (6 or 7), and a support device (2) of supplementary elements (3, 42), if necessary indicating a parameter of the ram functioning, such as bars (17) fixed on the external surface of the body (4), characterized in that the fixing means (20, 20') of the support device (2) are mounted in the feeding ports (8) and are formed by members likely to be introduced each one, notably screwed, in a feeding port (8), each member (20, 20') passed by a channel allowing the inlet of the forced fluid to the interior of the ram.
