Publication number: 20190085536Abstract: An improved expansion tank is provided for at least temporarily storing a pumped liquid under pressure, the expansion tank comprising a thin walled outer shell formed of two substantially hemispherical domes joined together, either directly or at the two ends of a central, substantially cylindrical section, and a flexible diaphragm located internally of the tank and secured to the inner surface of the shell of the tank to divide the internal volume of the tank into a fluid-tight section holding a gas under pressure and a fluid-tight section for holding an aqueous liquid under pressure. The improvement comprising diaphragm coupling ring formed as a discrete part of the diaphragm tank that can be fabricated independent of the domes and any cylinder. The diaphragm coupling ring provides a robust, leak-proof seal with the diaphragm, so that it can be connected onto an inner surface of an expansion tank in a separate, secondary operation.Type: ApplicationFiled: March 30, 2017Publication date: March 21, 2019Applicant: FLEXCON INDUSTRIES, INC.Inventors: Thomas W. Wideman, Lucas Murphy, Travis Bergmiller, Robert Lombari, Gretchen Sharfman, Nelson Sharfman, Michael Kennedy

Patent number: 7108015Abstract: An in-line expansion tank. As fluid traverses a pipe within the tank, it may pass into and displace a diaphragm disposed outside of the pipe if the fluid pressure is greater than a tank pressure pushing the diaphragm against the pipe. When the fluid pressure decreases, the fluid passes from the diaphragm back into the pipe.Type: GrantFiled: July 24, 2003Date of Patent: September 19, 2006Assignee: Flexcon IndustriesInventors: Robert Lombari, Wei-Chiao Lo

Patent number: 7052243Abstract: A pressure maintenance assembly for a domestic water well system. The assembly comprises a pressure maintenance valve having an inlet side and an outlet side, a pressure tank in fluidic communication with the outlet side, and a calibrated bypass. When the valve is closed, the calibrated bypass provides fluidic communication between the inlet side and the outlet side. The size of the calibrated bypass and the pressure tank are adapted and constructed to permit a flow rate between the inlet side and the outlet side that will fill the pressure tank in a time interval less than twice the time required to pump a volume of water that will dissipate heat generated by the pump when it is turned on.Type: GrantFiled: September 7, 2004Date of Patent: May 30, 2006Assignee: Flexcon IndustriesInventors: Gerard Duggan, Robert Lombari, David van Houten

Publication number: 20050051223Abstract: A tubular expansion tank. Fluid may pass into and displace a diaphragm disposed outside of a pipe within the tank if the fluid pressure is greater than a tank pressure pushing the diaphragm against the pipe. When the fluid pressure decreases, the fluid passes from the diaphragm back into the pipe and out of the tank.Type: ApplicationFiled: September 9, 2003Publication date: March 10, 2005Inventors: Robert Lombari, Wei-Chiao Lo

Patent number: 6305416Abstract: Hydraulic actuator. An actuator body includes an inlet, an outlet, a port communicating with a pre-charged diaphragm tank, and a port communicating with a pressure switch. The actuator body includes a movable member which, in a first position, closes the inlet port and provides fluidic communication with the pressure switch port while allowing pressure equalization between the inlet and an interior of the actuator body. In a second position, the movable body opens the inlet port and seals the pressure switch port. A spring is disposed within the actuator body to urge the movable member toward the first position. The invention eliminates the need for multiple springs as shown in one prior art design and eliminates the need for reliance on a hydrostatic force differential to move the movable member.Type: GrantFiled: March 24, 2000Date of Patent: October 23, 2001Assignee: Flexcon IndustriesInventors: Fred Snel, Stefan Beekhuis, Wolf Joerg, Robert Lombari

Patent number: 6264247Abstract: A full flow water connector assembly has a connector with prongs of a certain length that are separated by notches. The end of the connector with the prongs is passed through an opening in a diaphragm and the prongs protrude through respective slots in a diffuser/retainer member. The prongs are then bent so as to press the diffuser/retainer member so as to secure the diaphragm and hold the connector assembly together. The diffuser/retainer member has segments between the slots, the segments contacting the notches when the diffuser/retainer member is pressed sufficiently far. The length of the prongs beyond the notches limits the maximum amount of compression that the diffuser/retainer member can exert against the diaphragm material, thereby minimizing the chance of cracking and subsequent failure of the diaphragm material.Type: GrantFiled: June 25, 1998Date of Patent: July 24, 2001Assignee: Flexcon Industries, Inc.Inventors: Robert Lombari, Wolf Joerg, Fred Snel
