Publication number: 20100313971Abstract: A pressure regulator comprising a housing having an inlet port and an outlet port, a linearly sliding member for selectively covering a section of a passage between the inlet port and the outlet port, a diaphragm interconnected to the linearly sliding member to slide the linearly sliding member in reaction to pressure levels in the housing, and a valve seat located in the passage between the inlet port and the outlet port. The linearly sliding member includes a sealing disc for preventing fluid flow past the valve seat. The valve seat is located closer to the outlet port than to the inlet port.Type: ApplicationFiled: April 1, 2010Publication date: December 16, 2010Inventors: J. Reese Moore, Robert Clifton Jones, JR., Brian Keith Yutzy, Thomas V. Lozito, Charles M. Olds, Angelica Wright

Patent number: 7328718Abstract: A pressure regulator (10) includes a changeover regulator (12) with plural inlets (16, 18). Inside the regulator, each inlet has a closure member (62) connected to a diaphragm (100) for control of the closure members (62) in response to pressure inside the regulator (12). Biasing members (56) are stabilized in position by either an apertured plate (102), a cup (104) or both. A changeover handle (19) depresses one spring (56) or the other to bias one closure member (62) open to admit gas from the associated inlet (16 or 18).Type: GrantFiled: December 9, 2003Date of Patent: February 12, 2008Assignee: S.H. Leggitt CompanyInventors: Charles M. Olds, Edward R. Lee

Publication number: 20070272313Abstract: A two-stage pressure regulator comprising a regulator housing comprising a bonnet, a first regulator body having a top connected to the bonnet and a bottom connected to a second regulator body. The regulator housing has an inlet, a first flow path, a second flow path and an outlet. The regulator housing has a first regulating cavity formed between the first regulating body and the second regulating body and a second regulating cavity formed between the bonnet and the first regulating body. A first diaphragm is in the first regulating cavity and a second diaphragm is in the second regulating cavity. A first regulating assembly is operatively connected to the first diaphragm for preventing fluid flow through the first flow path and a second regulating assembly is operatively connected to the second diaphragm for preventing fluid flow through the second flow path.Type: ApplicationFiled: May 22, 2007Publication date: November 29, 2007Inventor: Charles M. Olds

Patent number: 7261119Abstract: A pressure regulator comprising a housing, a pivoting lever selectively covering a passage between an inlet port and an outlet port of the housing, a diaphragm interconnected to the lever to rotate the lever in reaction to pressure levels in the housing, and a closure member abutting the pivoting lever and covering the passage to prevent fluid flow through the passage. The pressure regulator can have the closure member not being directly connected to the lever, a stabilizer element frictionally abutting a pivot pin as the lever rotates to thereby stabilize movement of the lever, an adjustment member that translates rotational movement of an adjustment cap into compression or decompression of a biasing element without applying a rotational force to the biasing element, and/or the cap including a tab configured to be selectively inserted at least one slot on the housing to prevent rotation of the adjustment cap.Type: GrantFiled: February 1, 2005Date of Patent: August 28, 2007Assignee: S.H. Leggitt CompanyInventor: Charles M. Olds

Patent number: 6971403Abstract: A pressure regulator having a housing with an inlet port and an outlet port. A plug is located within the housing and dividing the housing into an upper chamber and a lower chamber, with the upper and lower chamber being connected by a vent. The plug includes a fluid path between the inlet port and the bore. A yoke is adapted selectively close the fluid path in the plug. A diaphragm is located in the upper chamber and is connected to the yoke. A biasing member biases the yoke to open the fluid path through the plug. The diaphragm is configured to move the yoke to open the fluid path when pressure in the lower chamber and vented to the upper chamber through the vent is above a predetermined amount. The pressure regulator can also include a second biasing member used to positively close the fluid path through the plug.Type: GrantFiled: March 10, 2003Date of Patent: December 6, 2005Assignee: S. H. Leggitt CompanyInventors: Paul W. Heald, Christopher G. Turney, Loftus A. Fitzwater, III, Mark E. Hood, Charles M. Olds, Brian K. Yutzy

Publication number: 20040007270Abstract: A pressure regulator comprising a housing, a pivoting lever, a diaphragm and a stabilizer element. The housing has an inlet port and an outlet port. The pivoting lever selectively covers a section of a passage between the inlet port and the outlet port. The diaphragm is interconnected to the pivoting lever to rotate the lever in reaction to pressure levels in the housing. The stabilizer element is movable with the pivoting lever. The stabilizer element frictionally abuts a portion of the housing as the pivoting lever rotates to thereby stabilize movement of the pivoting lever.Type: ApplicationFiled: February 27, 2003Publication date: January 15, 2004Inventor: Charles M.

Patent number: 5996617Abstract: A two stage gas pressure regulator with a body housing having a gas inlet and a gas outlet, and a common interior wall dividing the body housing into two chambers forming two pressure reducing stages. Respective intersecting fluid passageways through the common interior wall communicate the first stage to the second stage and provide a gauge pressure tap on the body housing, the intersecting passageways meeting at an intersection point within the common interior wall. Respective diaphragms are provided for each stage, and a cover has a vent venting the volume defined between the cover and the second stage diaphragm. A small passageway is provided in a common cover wall between the two stages, the small passageway being sized to suitably vent both cover portions above the respective diaphragms through the vent while eliminating overpressurization of the second stage in the event of pressure regulating failure of the first stage.Type: GrantFiled: April 2, 1998Date of Patent: December 7, 1999Assignee: Fisher Controls Internationals Inc.Inventors: Charles M.
