  • Patent number: 9989166
    Abstract: Embodiments provide systems and methods for an actuating system for inflating an inflatable structure in which a pressurized fluid piston is coupled directly to the valve an inflatable structure. The coupling of actuator to valve is such that the pairing will remain rigid and secure until the deliberate act of operating the actuator. When the actuator is operated, the actuator displaces a translating chock. This activation simultaneously (a) decouples the valve from actuator, allowing the inflatable to deploy without impedance and (b) activates the inflation of the structure via the valve.

  • Patent number: 9958083
    Abstract: The force limited valve actuator operates on light-duty valves. The actuator includes signal controlled motor which drives a two piece threaded screw-nut drive. The nut connected to the motor and the screw connected to the valve stem. The nut has a spring loaded actuation surface/plate. The nut body has a positional indicator stem used as a valve-motor control. Operationally, the screw-nut-set moves between first, second and third positions. First: actuation plate at neutral and valve-stem at valve OPEN stop (example). Second: screw protrudes outboard of nut and valve-stem at CLOSE stop and actuation plate at neutral. Third: plate moves away from valve-stem (beyond neutral) while stem at CLOSE which third movement is a force sensor. First, second and third positions are all one way screw rotation. Force limited on stem by damper-shock absorber action. The positional indicator effects ON-OFF valve control.

    Abstract: A normally open non-electric valve includes a flow path through an apertured valve seat . . . cavity isolated from the flow path is sealingly closed off adjacent the valve seat by a flexible diaphragm. The diaphragm is sufficiently flexible to be pushed and held away from the valve seat by fluid flowing in the flow path. When it is desired to close the valve, a pressure medium is introduced into the cavity so as to force the diaphragm against the valve seat and interrupt the fluid flow in the flow path. The normally open valve can inexpensively be converted from an inexpensive electric solenoid valve by removing the plunger, spring and coil from the electric valve, closing off the plunger cavity with a flexible diaphragm, and selectably introducing a pressure medium into the cavity when it is desired to close the valve.

  • Publication number: 20120161043
    Abstract: A method of preventing a mass flow controller from participating in crosstalk in an array of mass flow controllers is described. The method includes sensing and providing a signal indicative of a fluid pressure inside of a mass flow controller with a pressure sensor contained within the mass flow controller, determining a response of a control valve to a rapid pressure perturbation at the inlet of the mass flow controller using the signal indicative of the fluid pressure to avoid overcompensation for the rapid pressure perturbation, and adjusting a control valve contained within the mass flow controller downstream of the pressure sensor, based on the determined response, so that the mass flow controller avoids overcompensating for the rapid pressure perturbation. The pressure sensor is positioned such that the pressure sensor is sensitive to rapid pressure perturbations at the inlet of the mass flow controller.

  • Patent number: 7856333
    Abstract: The disclosure relates to a method for commissioning pneumatically operated actuators that are controlled by a positioner. To determine the drive type, a constant flow of pneumatic fluid is applied to the actuator during commissioning while a drive-specific characteristic curve of the fed back position is recorded over time. Then the measured characteristic curve is compared with a given specimen characteristic curve. The drive type is inferred from the level of difference or agreement between the drive-specific characteristic curve and the specimen characteristic curve.
