摘要： A fluid flow actuated valve for controlling the fluid flow in a cooling conduit in an aircraft gas turbine engine, comprises a support structure adapted to be mounted within the conduit and at least one flap member pivotally mounted to the support structure. The at least one flap member is pivotable between a first position for a minimum fluid flow and a second position for a maximum fluid flow. A torsion spring is attached to the at least one flap member to urge the same to pivot against a fluid pressure differential, from the first position to the second position when the fluid pressure differential is smaller than a predetermined level.

摘要： A dual plate check valve has flaps (6) mounted on one or more hinge pins (7). The ends of the hinge pins (7) are received in sockets in inserts (12), which inserts (12) are receivable in open-sided recesses (13) formed in the annular valve housing (1) and are held in place by a keeper (14) located in a generally radially outwardly extending slot (15) formed in that housing (1). Where a single hinge pin (7) is used in a vertical orientation to support both flaps (6), a cylindrical bearing member may be supported by a lower one of said inserts (12) to extend through a lower hinge lug (21) of the first flap and partially through a lower hinge lug (20) of the second flap, thereby to support the lower hinge lug of the second flap independently of the first flap.

摘要： A check valve 12 includes a circular check valve flange 20 that circumscribes a central axis and defines an outer perimeter of the check valve 12. The check valve also includes a first tab 22 that extends radially outward from the check valve flange and has a first circumferential width and a first radial length. The check valve also includes a second tab 24 that extends radially outward from the check valve flange and has a second circumferential width and a second radial length. The first circumferential width is different than the second circumferential width and the first radial length is greater than the second radial length. The first tab 22 and the second tab 24 of the check valve are disposed about the check valve flange 20 at an angle other than 180 degrees apart.

摘要： The present invention relates to a dual plate check valve assembly (30) for controlling the direction of flow in a piping system. The dual plate check valve comprises a disc assembly (120) arranged inside a valve body comprising two or more disc members (12a, 12b) adapted to engage with a valve seat to control the flow through a valve bore of the valve body. Further, the disc assembly is displaceable arranged inside the valve body in a transverse direction in relation to the direction of flow, and the dual plate check valve assembly comprises a rising stem mechanism (4) configured to transversally displace the disc assembly between a lowered position and a raised position wherein the disc assembly is lifted at least partially clear of the valve bore to achieve free flow through the valve bore in both directions.

摘要： A check valve in which a stop pin assembly (6) is situated so as to prevent the movement of a flapper (4) beyond a predetermined position. In a preferred embodiment the check valve has two flappers with the stop pin assembly situated there between to prevent either one of them from pivoting beyond an essentially vertical position. The stop pin assembly is configured such that it can be inserted and locked in place when the check valve is inserted within a valve body that contains the check valve. The stop pin assembly can comprise three elements including a central portion and first and second end portions, although the stop pin assembly could instead comprise a single element. The stop pin assembly is inserted between two holders (5) and in a preferred embodiment is rotatable to a locking position where it is affixed in place by fasteners.
