    Abstract: A device for double-acting hydraulic systems with a slave cylinder (1) and a master cylinder (72) whose piston (76) can be moved to a position, wherein fluid can flow both ways between a master cylinder space (73, 74) and a reservoir (92) for hydraulic fluid. For each slave cylinder space the slave cylinder (1) has a vent nipple boring (12, 22) with an internal section (16, 26), i.e. a section located near the cylinder space (2), which is in the form of a seat. A first end section (41, 51) of a vent nipple (40, 50) with a through-going nipple channel (60) can abut sealingly against the seat and thereby close the nipple boring (12, 22) when the nipples (40, 50) are screwed completely into the nipple borings (12, 22). The hydraulic system can be connected to an evacuation device. An external section (19, 29) of the nipple borings (12, 22) is arranged to slidably and sealingly abut against the second end section (44, 54) of the nipples (40, 50) both when the first end section (41, 51) of these closes and opens the nipple boring (12, 22). A connecting channel (35) provides communication between the nipple borings (12, 22). Furthermore the nipple channel (60) cooperates with a device (63) which prevents fluid flow from the second end section of the nipple towards the first.

    Abstract: Der hydaulische Servo-Aktuator schliesst eine Kolbenstange (3) ein und darauf zwei in Tandem angeordnete Kolben (K1, K2), die beide in je einem gesonderten Hydraulikzylinder (Z1, Z2) verschiebbar gelagert sind. Es sind zwei separate redundante Hydraulikkreise (1, 2) gebildet, die mit dem hydraulischen Systemdruck arbeiten, gespiesen von einer zugeordneten Hydraulikpumpe. Durch Absenken und Anheben des Druckes in einer Steuerleitung (P1S, P2S) durch je ein Steuerventil (SV1, SV2) auf einer der Kolbenseiten ist in der Folge die Kolbenstange (3) aus- und einfahrbar. Dadurch ist ein am Ende der Kolbenstange (3) angelenkter Aktionshebel (26), der ausserdem an einem weiteren Schwenkpunkt (27) am Servo-Aktuator angelenkt ist, hin und her schwenkbar.

    Abstract: Applicable in installations that comprise a reaction bar (1) located above an actuator (4), and both attached to a first piece (2) and to a second piece (3) for producing the relative displacement between the first piece (2) and the second piece (3). It also comprises two supports (6) which are fixed to the reaction bar (1) and which, by means of some vertical arms (7), support two horizontal bars (8) which are located facing and parallel to the lateral sides of the actuator. It includes a cable (9), located around each one of the horizontal parallel bars (8), whose ends are fixed to the lateral sides of the actuator (4) so that, when disconnection takes place of the actuator from the first piece (2) or second piece (3), said actuator (4) is kept retained by means of the safety device.
