摘要： An actuator release mechanism comprising: a longitudinal sleeve (6) movable along an axis between a lock position and a release position; drive means for causing the longitudinal sleeve to move along the axis; and bias means (3) to bias the longitudinal sleeve to the lock position; wherein the drive means comprises: a rotary solenoid (1) having a first direction of rotation and a second direction of rotation; a toggle member (4) having a toggle shaft (401) connected to and rotatable with the rotary solenoid, and a toggle head (402) in engagement with the longitudinal sleeve by means of at least one pin (5) extending radially inwards from the longitudinal sleeve and a helical guide rail (7) provided on a radially outer surface of the toggle head, the longitudinal sleeve being mounted around the toggle head, such that rotation of the solenoid causes rotation of the toggle member and the guide rails which causes the pin(s) to ride along the guide rail to rotate the sleeve and cause axial movement of the sleeve relative to the toggle member.

摘要： A toggle release mechanism (100) comprises a base element (102), a toggle element (104) and an actuating rod (142). The toggle element (104) is rotatably mounted at a first end (112) to the base element (102) about a first axis (114) for rotation between a first, locking position and a second, release position. The actuating rod (142) has a central portion (144) extending through the toggle element (104) and first and second end portions (146, 148) projecting on opposed sides thereof for engagement with actuators (154) arranged on opposed sides of the release mechanism (100). The actuating rod (142) further comprises a mounting flange (156) projecting therefrom at a boundary between the central portion (144) and a first end portion (146). The mounting flange (156) has a first hole (158) therein for receiving a first fastener (160). A surface (162) of the toggle element (104) facing the mounting flange (156) has a bore (164) formed therein for receiving the first fastener (160). The mechanism further comprises a mounting element (166) slidably received on the second end (148) of the actuating rod (142). The mounting element (166) has a bore (168) for receiving the second end (148) of the actuator rod (142) and a second hole (170) for receiving a second fastener (176). A surface (174) of the toggle element (104) facing the mounting element (166) having a second bore (176) formed therein for receiving the second fastener (172).

摘要： An actuator release mechanism comprising an axially moveable member such as a piston 39 biased in a first axial position by a bias spring 49 and driven to a second axial position by an actuation means such as a solenoid 41 arranged in substantially the same axis as the axially moveable member.

摘要： A locking mechanism comprising a linkage assembly (6) comprising:
a first link (6a) and a second link (6b) joined at a pivot point (110);
a linkage assembly spring (5) to bias the linkage assembly (6) into a first, locked, position;
a rotational rod (1) having a cam (120) formed thereon with a cam surface in engagement with the linkage assembly in the region of the pivot point (110);
a solenoid assembly (3) arranged, in a first mode, to rotate the rotational rod (1) such that the cam (120) acts as a stop against the linkage assembly (6) at the pivot point (110) in a locked position, and, in a second mode to rotate the rotational rod (1) such that the cam surface presses against the linkage assembly sufficiently (6) to overcome the linkage assembly spring (5) and to force the linkage assembly (6) into a second, unlocked position.

摘要： A check valve (2) comprises an annular housing defining a generally circular opening (8). A plurality of radially extending arms (10) extend across the circular opening (6) from the centre (12) of the valve housing (4) to respective nodes (14) at the periphery of the valve housing (4). A plurality of cross arms (16) extend between circumferentially adjacent nodes (14), thereby dividing the circular opening (6) into a plurality of primary, generally triangular radially inner openings (18) and a plurality of secondary, generally segment shaped radially outer openings (20). A plurality of primary, generally triangular flapper elements (22) close the primary openings (18) and a plurality of secondary, generally segment shaped flapper elements close the secondary openings (20). Respective mounting posts (26) are arranged at a respective node (14) and a respective hinge pin (28) is mounted between respective circumferentially adjacent mounting posts (26). A primary flapper element (22) and a secondary flapper element (24) are hingedly mounted to each hinge pin (28) for pivoting between a closed position in which they close their respective primary and secondary openings (18, 20) and an open position in which they permit flow through their respective primary and secondary openings (18, 20).
