Patent number: 11692636Abstract: The present disclosure relates to a hydrostatically adjustable flow control valve. In one embodiment, the valve includes a fixed sleeve that slidably receives a spool. A spring biases the spool relative to the fixed sleeve. A primary orifice is used to deliver fluid to the interior area of the fixed sleeve and spool. A control device is used to selectively vary the rate at which fluid drains from the interior area. Draining the fluid results in the spool being received within the interior of the fixed sleeve. The movement of the spool opens flow ports within the sleeve. This, in turn, allows fluid to exit the valve. Conversely, the control device can be set to prevent fluid drainage. This results in the spool extending from interior of the fixed sleeve, the closure of the flow ports, and the sealing of the valve.Type: GrantFiled: November 20, 2020Date of Patent: July 4, 2023Assignee: FLOW DYNAMICS, LLCInventor: Jeffrey Alan Chalfin

Patent number: 11105343Abstract: The present invention relates in general to the field of fluid reaction surfaces, and more specifically, to a fluid-foil impeller and method of use. One aspect of the fluid-foil impeller utilizes a plurality of fluid-foil discs that may be of uniform and/or variable thickness and configured to rotate rapidly in series to produce propulsion. Each fluid-foil disc comprises a leading edge, a trailing edge, a chord and a fixed pitch. The fluid-foil impeller may further include a standard or Venturi shroud that is designed to encompass the plurality of fluid-foil discs. The plurality of fluid-foil discs are configured to act in cooperation with the shroud to reduce losses incurred from turbulence and the conversion of mechanical work to fluid movement. Fluid may be acted upon by the plurality of fluid-foil discs and/or shroud, singly or in an array.Type: GrantFiled: December 16, 2019Date of Patent: August 31, 2021Assignee: Smith Flow Dynamics, LLCInventors: Robert J. Kosmicki, Perry D. Smith, Jacob B. Smith, Julianne S. Smith

Patent number: 11016512Abstract: Disclosed is a system and valve assembly that can be used to promote the laminar flow of a variety of fluids and gases. In one embodiment, the valve assembly can be used to remove entrained water bubbles from a water supply. This, in turn, increases the density of water running through an associated water meter. This ensures that the water meter is not inaccurately including entrained air as metered water. The result is more accurate water readings and reduced utility bills. The assembly can be externally adjusted using an adjustment tool so as to increase or decrease the tension on an interior spring which, in turn, increases or decreases the rate at which the interior block oscillates.Type: GrantFiled: May 8, 2018Date of Patent: May 25, 2021Assignee: Flow Dynamics, LLCInventor: Jeffrey Alan Chalfin

Patent number: 10544569Abstract: A system and valve assembly that is adapted to increase the efficiency of an upstream water meter. By way of the valve assembly entrained water bubbles can be removed from a water supply. This, in turn, increases the density of the water running through the water meter. This ensures that the water meter is not inaccurately including entrained air as metered water. The result is more accurate water readings and reduced utility bills. The assembly can be externally adjusted using an adjustment tool so as to increase or decrease the tension on an interior spring which, in turn, increases or decreases the rate at which the interior block oscillates.Type: GrantFiled: April 25, 2017Date of Patent: January 28, 2020Assignee: Flow Dynamics, LLCInventor: Jeffrey Alan Chalfin

Publication number: 20160131380Abstract: A method, a method for designing a system, and a system for creating substantially continuous circulation within a volume to be managed using one or more devices that are neither HVAC-based nor duct-based. The method includes one or more devices continuously drawing air, continuously processing air, and continuously pushing air through at least three exit zones. The method for designing a system includes determining the approximate volume of the facility or the approximate volume of air to be managed within the facility, determining the location of objects with an impact on air flow or temperature of the facility, and determining the number, type, and preferred locations of the one or more devices to install in the facility. The system includes one or more devices continuously drawing air, continuously processing air, and continuously pushing air through at least three exit zones.Type: ApplicationFiled: November 6, 2015Publication date: May 12, 2016Applicant: INTERNAL AIR FLOW DYNAMICS, LLCInventors: Roy H. Price, Albert E. Fiorini, Mark A. Price

Patent number: 8460443Abstract: A portable dust collector comprises a rectangular box-shaped housing containing a rectangular box shaped filter chamber having a dust collection volume in a lower portion thereof and providing plenums for operative gas circulation in a compact environment. The filter chamber shares a portion of the floor with the housing and has a pair of internal parallel sidewalls spaced inwardly from the outside sidewalls of the housing. The internal sidewalls define a plurality of filter chamber dirty gas inlets located just under an apertured cell plate from which the filters hang. The system is provided with a pulse jet cleaning system located in the clean air plenum above the cell plate.Type: GrantFiled: October 27, 2009Date of Patent: June 11, 2013Assignee: Jet Flow Dynamics, LLCInventor: Michael W.
