    摘要： A valve apparatus (10) comprises a housing (12) defining a flow path (14), a valve seat (42) located within the housing (12) around a periphery of the flow path (14), a carriage member (16) located within the housing (12), a cutting arrangement (28) mounted on the carriage member (16), and a valve member (32) mounted on the carriage member (16) via a connection assembly (34) which permits relative movement between the valve member (32) and the carriage member (16). The carriage member (16) is moveable from a first position towards a second position to drive the cutting arrangement (28) across the flow path (14) and to move the valve member (32) into a position in which relative movement between the valve member (32) and the carriage member (16) permits the valve member (32) to sealingly engage and disengage the valve seat (42) to control flow along the flow path (14).

    摘要： A check valve assembly (100, 200) is provided for subsea applications. The check valve assembly comprises a housing (102, 202), having an inlet port (106, 206) and an outlet port (108, 208) forming an internal fluid passageway through the housing;, a valve member (112, 212), moveable within the internal fluid passageway between a first position, where fluid flow through the internal fluid passageway is prevented, and a second position, where fluid flow through the internal fluid passageway is permitted; a biasing member (110, 210), adapted to urge the valve member into the first position at a predetermined cracking force, and a pressure interface (116, 216). The pressure interface operatively links the valve member and an external fluid of a region exterior of the check valve assembly so as to provide a supplemental force, proportional to the ambient pressure of the external fluid, adapted to urge the valve member towards the first position.

    摘要： A magnetic holding brake (1) having at least one turning brake member (4) allocatable to a rotatable part (2) of an actuator (3) and a fixed brake member (6) allocatable to a torque-proof part (5) of the actuator (3). The turning brake member (4) and the fixed brake member (6) each at least have one permanent magnet (7, 8) of different polarity. The permanent magnets are lying opposite to each other in a pre-defined relative position of the turning brake member (4) and the fixed brake member (6) under exertion of a braking or holding torque. In this manner, the possibility exists that a holding in the so-called “fail as is”-mode is more easily and reliably and at the same time cost-efficiently achievable without wear or further energy demand.

    摘要： A selectively operable downhole valve for use with core sampling apparatus, the valve comprising a throughbore through which a first body may pass, and an obstructing member which is capable of selectively obturating the throughbore, the obstructing member being arranged to open or close the throughbore by movement of the first body with respect to the valve. A core sample of the formation may then be obtained and retrieved from the bore under pressure since the valve seals the bore downhole. Retrieving the sample under pressure maintains the integrity of the core sample so that subsequent analysis of the sample will more closely reflect the true characteristics of the formation.
