Publication number: 20240019056Abstract: A clamp for sanitary pumps includes a tensioning assembly mounted on a ring. The tensioning assembly includes an adjustment assembly that interfaces with first and second brackets disposed at first and second ends of the ring. The adjustment assembly includes a nut that interfaces with a rod at a threaded interface. A head is disposed at an end of the rod opposite the nut and interfaces with the second bracket. The nut and rod are coaxial and an orientation of a common adjustment axis can be changed by pivoting the adjustment assembly relative to the first bracket, to maintain concentricity between the nut and rod.Type: ApplicationFiled: November 29, 2021Publication date: January 18, 2024Inventors: Mark S.

Patent number: 11292710Abstract: A fluid management system includes a fluid management controller and a fluid dispenser. The controller authorizes control of the one or more fluid management components over a wireless interface. A dispensing meter can be activated by an authentication device. The fluid meter includes a cartridge valve with a valve cartridge and a valve stem. The cartridge valve guides the valve stem and provides the only sealing surface for the dynamic seals and control seal disposed on the valve stem. The handheld meter dispenses through a nozzle, which includes an overmolded stem tip that generates a laminar fluid flow as the fluid exits the nozzle. The handheld fluid meter includes circuitry configured to invert the orientation of a visual output provided by a display of the handheld fluid meter to facilitate installation of the handheld fluid meter for use in an oil bar application.Type: GrantFiled: October 11, 2019Date of Patent: April 5, 2022Assignee: Graco Minnesota Inc.Inventors: Benjamin J.

Patent number: 10801667Abstract: A system for harvesting energy from a lubrication event includes a fluid pump, a fluid injector, an energy harvesting device, a wireless transmitter, and a controller unit. The fluid injector receives fluid from the fluid pump. The fluid injector is connected to the energy harvesting device, which is configured to produce electrical energy in response to a firing of the fluid injector. Electrical energy produced by the energy harvesting device powers the wireless transmitter, which is configured to transmit a wireless signal. The wireless signal indicates that the fluid injector fired. The wireless signal is received by the controller unit, which controls the fluid pump.Type: GrantFiled: April 27, 2016Date of Patent: October 13, 2020Assignee: Graco Minnesota Inc.Inventors: Benjamin J.

Patent number: 10781971Abstract: An autofill shutoff valve includes a valve body mounted to a lubricant reservoir and secured to a fill tube extending into the reservoir. The autofill shutoff valve has a valve stem extending through the valve body and into the lubricant reservoir. The valve stem is actuated by a plate disposed within the reservoir from a first position, wherein lubricant flows from a lubricant inlet to a lubricant outlet through the valve body, to a second position, wherein the valve stem blocks the flow of lubricant through the valve body. The autofill shutoff valve provides lubricant directly to the reservoir, thereby eliminating external plumbing and the autofill shutoff valve also prevents overfill of the reservoir by cutting off the flow when the reservoir is full.Type: GrantFiled: April 22, 2016Date of Patent: September 22, 2020Assignee: Graco Minnesota Inc.Inventors: John C. Holman, Mike V. Atkinson, Brandon T. Gustafson, Benjamin J. Paar

Patent number: 10731791Abstract: A centerfill assembly for a lubricant reservoir includes a hollow tube for receiving lubricant from the top of the reservoir and loading the lubricant into the reservoir near the bottom of the reservoir. Loading the lubricant near the bottom of the reservoir introduces lubricant near where the stirring paddles mix the lubricant and near where the lubricant is loaded to the lubricant pump. Adding the lubricant near where the pumps load and near the stirring paddles helps to eliminate air pockets in the lubricant. In addition, having the centerfill rod minimizes exterior plumbing and allows for the mounting of valves on the fill line.Type: GrantFiled: April 22, 2016Date of Patent: August 4, 2020Assignee: Graco Minnesota Inc.Inventors: John C. Holman, Benjamin J. Paar, Mike V. Atkinson, Brandon T. Gustafson

Patent number: 10589979Abstract: A fluid management controller includes a processor, a wireless interface, and a memory. The wireless interface is configured to communicate between the processor and one or more fluid management components. The processor is configured to authorize control of the one or more fluid management components over the wireless interface. The memory is encoded with instructions that, when executed by the processor, cause the processor to provide dispense authorizations to the one or more fluid management components and record fluid dispense information from the one or more fluid management components in the memory.Type: GrantFiled: March 22, 2018Date of Patent: March 17, 2020Assignee: Graco Minnesota Inc.Inventors: Benjamin J. Paar, Bradley G. Kahler, Chad G. Igo, Gregory D. Sieckert
