  • Patent number: 11947370
    Abstract: A fluid flow device that can measure and control a flow of a fluid is described. Various procedures, including measuring, controlling, balancing, or calibration procedures can leverage differential pressure measurement. These differential pressure measurements can be measured across the fluid flow device such that a first pressure measurement is taken upstream of the fluid flow device while a second pressure measurement is taken downstream of the fluid flow device. Moreover, one or more of the various pressure measurements, and in particular the downstream pressure measurement, can be performed at stagnation zone where the flow has stagnated. Such can provide significant amplification and/or turndown capabilities.

  • Patent number: 11920686
    Abstract: A driving tool includes a chamber to store compressed air and a relief valve in communication with the chamber. The relief valve includes an inflow channel communicating with the chamber and an outflow channel with a larger diameter formed at a downstream side of the inflow channel.

  • Patent number: 11885200
    Abstract: An electro-hydraulic control system for actuating a control valve includes a control module. The control module is coupled to the surface via at least one hydraulic line and two electrical power lines. The control module uses one of the hydraulic lines as a “supply” line and the other line as a “return” line if included. Each hydraulic line of the at least one hydraulic lines can be used as an “open” line or a “close” line to open or close the control valve. The control module includes two normally closed (NC) solenoid valves (SOVs) that are coupled to the electrical power lines and can be controlled from the surface to open or close. The opening or closing of the NC SOVs in cooperation with hydraulic pressure on a “supply” line of the hydraulic lines operates (i.e., closes or opens) the control valve.
