Publication number: 20190145397Abstract: In at least one illustrative embodiment, a diaphragm pump may comprise a sleeve formed to include (i) a bore extending along a longitudinal axis and (ii) a sleeve port that opens to the bore, and a spool supported in the bore of the sleeve and formed to include a spool port, the spool being configured to move with a diaphragm during at least a portion of a stroke of the diaphragm such that the spool slides relative to the sleeve and, when the diaphragm reaches a turndown position that is between first and second end-of-stroke positions, the spool port aligns with the sleeve port to cause a pilot signal to be supplied to a cut-off valve. At least one of the sleeve and the spool may be rotatable about the longitudinal axis to adjust a location of the turndown position relative to the first and second end-of-stroke positions.Type: ApplicationFiled: January 8, 2019Publication date: May 16, 2019Applicant: Ingersoll-Rand CompanyInventors: Jevawn Sebastian Roberts, Michael Brace Orndorff

Patent number: 9752566Abstract: Diaphragm pumps, and pre-charging systems for use with such pumps, are disclosed. The diaphragm pump includes a first diaphragm that separates a cavity into a motive fluid chamber and a pumped media chamber, a charge chamber having a controlled volume, wherein the controlled volume is adjustable to vary a controlled mass of compressed fluid capable of being stored in the charge chamber, and one or more valves configured to (i) fluidly couple the motive fluid chamber to an exhaust chamber during a first stroke period, (ii) fluidly couple the charge chamber to a compressed fluid inlet during at least a portion of the first stroke period, and (iii) fluidly couple the charge chamber to the motive fluid chamber during a second stroke period.Type: GrantFiled: June 26, 2014Date of Patent: September 5, 2017Assignee: Ingersoll-Rand CompanyInventors: Jevawn Sebastian Roberts, Michael Brace Orndorff

Patent number: 9316218Abstract: One or more techniques and/or systems are disclosed for increasing compressed air efficiency in a pump that utilizes an air efficiency device in order to optimize the amount of a compressed air in the pump. The air efficiency device may allow for controlling the operation of the air operated diaphragm pump by reducing the flow of compressed air supplied to the pump as the pump moves between first and second diaphragm positions. A sensor may be used to monitor velocity of the diaphragm assemblies. In turn, full position feedback is possible so that the pump self-adjusts to determine the optimum, or close to optimum, turndown point of the diaphragm assemblies. As such, air savings are achieved by minimizing the amount of required compressed air.Type: GrantFiled: August 8, 2014Date of Patent: April 19, 2016Assignee: Warren Rupp, Inc.Inventors: Mark D.

Publication number: 20150004006Abstract: Illustrative embodiments of diaphragm pumps with chamber crossventing, and methods of operating such pumps, are disclosed. In at least one illustrative embodiment, a method of operating a diaphragm pump may comprise communicating compressed fluid from a compressed fluid inlet to a first motive fluid chamber to cause first and second diaphragms to move to a first end-of-stroke position, communicating compressed fluid from the first motive fluid chamber to a second motive fluid chamber while the first and second diaphragms are in the first end-of-stroke position, communicating compressed fluid from the compressed fluid inlet to the second motive fluid chamber to cause the first and second diaphragms to move to a second end-of-stroke position, and communicating compressed fluid from the second motive fluid chamber to the first motive fluid chamber while the first and second diaphragms are in the second end-of-stroke position.Type: ApplicationFiled: June 26, 2014Publication date: January 1, 2015Inventors: Jevawn Sebastian Roberts, Michael Brace Orndorff
