Abstract (en)
[origin: EP0600381A1] A hydraulic actuating unit comprising a control member (11) formed by a first tubular member (19) defining a pair of cavities (38, 48) accommodating slidably respectively a second member (14) and a third member (43); the third member (43) incorporates a non-return valve communicating with a chamber (34), formed between the first member (19) and the second member (14), and with a supply duct (60) for hydraulic fluid, and is movable under the pressure of the hydraulic fluid and against the action of resilient means (44) from a rest position, in which it connects said chamber (34) with an outlet opening (37, 39) of the first member (19), into a second operating position in which said chamber (34) is isolated from the outlet opening (37, 39). <IMAGE>
