Patent number: 10203705Abstract: A pressure regulator has a pressure chamber connected to an inlet flow area which receives liquid flow. As liquid flows into a forward chamber of the pressure chamber, pressure is exerted on the forward face of the piston, which in turn causes the piston to slide longitudinally through the pressure chamber. An internal passageway through the piston fluidically connects the forward pressure chamber and rear pressure chamber such that as the piston slides into the rear pressure chamber pressure increases at the rear pressure chamber, which in turn forces the piston to move forwardly, thus regulating flow out of the pressure chamber. A hand wheel is configured to turn a movable plate located inside the pressure chamber, with the movable plate configured to impede the piston from moving rearwardly. Pressure sensors and vents with a pressurized air source may be used to keep the pressure within a desired range.Type: GrantFiled: April 21, 2017Date of Patent: February 12, 2019Inventor: Carroll G. Rowe

Patent number: 10107406Abstract: A valve assembly includes a valve body defining a main flow pathway (28) and a bypass channel (52) for bypassing the main flow pathway. A ball (20) is located in the main flow pathway and is moveable between an open position and a closed position. When the ball is in the open position, an open pathway through the ball fluidly completes the main flow pathway to provide an ordinary flow, and when the ball is in the closed position the ball blocks the main flow pathway. A pressure relief feature (50) is disposed in the bypass channel (52), and the valve body further defines a pressure relief passage (62) comprising a clearance between an outer surface of the ball (20) and the valve body. The pressure relief feature (50) permits a relief flow from the bypass channel (52) through the pressure relief passage (62) around the ball (20), and to the outlet (24) to relieve excess pressure in the connecting inlet piping (22).Type: GrantFiled: December 15, 2015Date of Patent: October 23, 2018Assignee: Parker-Hannifin CorporationInventor: Craig Obermark
