  • Patent number: 10928813
    Abstract: A pressure-type flow rate control device includes a restriction part, a control valve disposed upstream of the restriction part, an upstream pressure sensor, a downstream pressure sensor, and a controller that diagnoses flow rate control by using pressure drop data on a flow passage between the control valve and the restriction part and reference pressure drop data, wherein a close command is issued to the control valve and a shutoff valve provided downstream of the downstream pressure sensor, and the controller determines whether a predetermined critical expansion condition is satisfied by using outputs of the upstream pressure sensor and the downstream pressure sensor after the control valve is closed, and diagnoses flow rate control by using the pressure drop data acquired during a period in which the predetermined critical expansion condition is satisfied.

  • Patent number: 10677373
    Abstract: The disclosure discloses a servo-valve that controls a fluid discharged from a discharge port of a nozzle by displacing the nozzle and drives an actuator. The servo-valve includes a receiver that includes an inflow surface provided with a first inflow port and a second inflow port into which the fluid discharged from the discharge port flows. The nozzle includes a force generation portion that includes an end surface provided with the discharge port and an outer circumferential surface formed in the periphery of the end surface. When the nozzle is displaced from a neutral position toward the first inflow port, the fluid inside the second inflow port is blown out toward the nozzle. The force generation portion collides with the fluid blown out from the second inflow port and causes an assisting force in a direction matching a nozzle displacement direction toward the first inflow port. The nozzle easily moves by the assisting force generated in the force generation portion and thus a response speed is improved.

  • Patent number: 10526195
    Abstract: In an example, a method of supplying fuel to a fuel tank of a vehicle includes supplying, via a fuel line, fuel to a fuel tank of a vehicle at an initial rate of fuel flow. The act of supplying the fuel causes an electrostatic charge to accumulate on a surface of the fuel in the fuel tank. The method also includes determining a level of ionization of an air medium in the fuel tank, and determining an increased rate of fuel flow based on a difference between the determined level of ionization and a baseline level of ionization. The electrostatic charge accumulated on the surface of the fuel dissipates at an increased rate when the determined level of ionization of the air medium is higher than the baseline level of ionization. The method further includes supplying the fuel to the fuel tank at the increased rate of fuel flow.

  • Patent number: 10180058
    Abstract: An telemetry module includes a valve assembly having a gate defining gate valve flow ports and a valve seat defining valve seat flow ports. A first solenoid assembly is arranged on a first side of the valve assembly and includes a first valve train engageable with the gate and a first push solenoid operatively coupled to the first valve train to move the gate in a first direction. A second solenoid assembly is arranged on a second side of the valve assembly and includes a second valve train engageable with the gate and a second push solenoid operatively coupled to the second valve train to move the gate in a second direction opposite the first direction. Moving the gate in the first direction with the first solenoid increases flow through the gate and alternately moving the gate in the second direction with the second solenoid decreases flow through the gate.

  • Patent number: 10139216
    Abstract: An online method for reconfiguring pressure and position sensors in a hydraulic system is disclosed. In one step, a sensor drift condition, a recalibration request, or an unisolated fault condition is detected. In another step, a system pressure sensor or another sensor, such as a load-sense pressure sensor, is verified as a trusted master reference sensor. Another step includes measuring and recording a first pressure reading at the master reference sensor and first voltage readings associated with first, second, third, and fourth pressure slave sensors at a first pump pressure set point. Another step includes, repeating the previous step at a second pump pressure set point. A new gain and offset for each of the first, second, third, and fourth pressure sensors can be calculated based on a comparison of the recoded first and second pressure readings and the recorded first and second voltage readings.

  • Patent number: 10103017
    Abstract: The invention relates to the preparation of samples on mass spectrometric sample supports with dispensing of liquids, and particularly to devices and methods to clean the dispenser. During dispensing of hundreds of samples, solved material may crystallize over time as deposit at the capillary tip of the dispenser, which impedes the vertical detachment of the drop in the medium and long run. Therefore, frequently cleaning the capillary tip is essential for a robust operation of the preparation device. The invention proposes to automatically clean the dispenser tip by creating a drop of washing fluid, such as pure solvent, fully enclosing the dispenser tip. The washing fluid is fed through a channel outside the central dispenser capillary to a location slightly above the capillary tip. The size of the hanging drop of washing fluid is photometrically regulated and monitored to prevent it from falling off prematurely.
