摘要： A valve (200) for controlling the flow of hydraulic fluid to a hydraulic motor (214) is disclosed. The valve (200) includes a sleeve (209) and a spool (212). The sleeve (209) includes a first fluid flow port (201) for receiving hydraulic fluid from the supply line (223); a second fluid flow port (202) for supplying hydraulic fluid to a second valve (213); a third fluid flow port (203) for receiving hydraulic fluid from a first control line (220a); a fourth fluid flow port (204) for receiving hydraulic fluid from a second control line (220b); and a fifth fluid flow port (205) in fluid communication with the return line (224). The valve (200) is arranged to be actuated to move the spool (212) between a first position and a second position. When the spool (212) is in the second position, the fifth fluid flow port (205) is in fluid communication with the second, third and fourth fluid flow ports (202, 203, 204) and the first fluid flow port (201) is closed by the spool (212).

摘要： A Stability and Control Augmentation System ("SCAS") module includes a SCAS actuator (610). The SCAS actuator (610) has a substantially cylindrical hydraulic chamber having a first and second regions (620, 625). A piston (630) is arranged for linear motion in first and second directions along an axis of the hydraulic chamber. The SCAS module (600) also includes a valve system (635) for controlling a flow of a hydraulic fluid into the hydraulic chamber. The valve system (635) has: at least one supply line (672) arranged to provide a first fluid flow path to the first region (620) of the hydraulic chamber and/or a second fluid flow path to the second region (625) of the hydraulic chamber, and a moveable valve member (660) arranged to have a position between a first and second positions.

摘要： A valve assembly 100 for an anti-ice system of an aircraft. The valve assembly 100 comprises: a valve body 110; a first piston 120; and a regulating piston 140. The valve body 110 defines a valve inlet 112, a valve outlet 114, a fluid passage between the valve inlet 112 and the valve outlet 114, and a core portion 116 defining a first chamber 112 by cooperation with the first piston 120 and a regulating chamber 142 by cooperation with the regulating piston 140. The first piston 120 is moveable between a first position and a second position, and the regulating piston 140 is movable between a first position and a second position. The first piston 120 overlaps the regulating piston 140 when the first piston 120 is its first position and the regulating piston 140 is in its second position.

摘要： An apparatus (100) for regulating a torque limiter, comprising a resilient member (130) configured to exert a force on one or more components of the torque limiter, wherein the force exerted by the resilient member (130) adjusts a torque limit of the torque limiter in use, a movable abutment (180) configured to contact the resilient member (130) and translatable in an axial direction to vary the force exerted by the resilient member (130), a nut (170) rotatable about the axis and configured to contact the movable abutment (180) such that a given rotational position of the nut (170) corresponds to a given axial position of the movable abutment (180), and an anti-rotation member (160) configured to move between first and second positions. In the first position the anti-rotation member (160) prevents rotational movement of the nut (170) and, in turn, prevents axial movement of the movable abutment (180), and in the second position the anti-rotation member (160) does not prevent rotational movement of the nut (170) and permits rotation of the nut (170) and, in turn, axial movement of the movable abutment (180) to vary the force exerted by the resilient member (130).
