摘要： Positive drive valve actuating mechanisms useable to operate a valve of a reciprocating compressor for oil and gas industry and related methods are provided. The valve actuating mechanism includes a driver configured to perform a rotating motion and a follower connected to a mobile part of the valve and to the driver. The follower is configured to transform the rotating motion of the driver into a reciprocating motion to open the valve and to close the valve, respectively.

摘要： A double suction impeller is disclosed. In at least one embodiment, the impeller is configured for centrifugal pumps and hydraulic power recovery turbines. The impeller's flow-path arrangement comprises inter-blade channels, intersecting each other at the impeller's outer diameter and defining a variable cross section shape, so that the equivalent number of blades is at least doubled with respect to a conventional configuration obtained by the coupling of two single suction impellers and an improved control over the velocity of the flow within the inter-blade channels is achieved.

摘要： An apparatus (10; 110; 310) for conveying a tool (12; 112; 312) into and/or from a well installation (W) comprises a conveying arrangement (16; 116; 316) configured for coupling to a housing (14; 114; 314) for receiving the tool to be conveyed (12; 112; 312). The conveying arrangement (16; 116; 316) includes an actuator arrangement (28; 128; 328) configurable between a retracted configuration and an extended configuration. The apparatus (10; 110; 310) is configured for location on a wellhead (WH) of the well installation (W), movement of the actuator arrangement (28; 128; 328) between the retracted configuration and the extended configuration moving the tool to be conveyed (12; 112; 312) into and/or from the housing (14; 114; 314) and thus into and/or from the well installation (W).
