Patent number: 11420220Abstract: A mixing module includes two inlets, an integrator, and a valve member. The integrator has two chambers each having a near end and a far end, and the valve member is movable between two positions. One of the inlets is connected to the near end of one of the chambers and the other inlet is connected to the near end of the other chamber when the valve is in one position. When the valve is in the other position, one of the inlets is disconnected from the chambers and the near ends of the chambers are connected.Type: GrantFiled: May 20, 2019Date of Patent: August 23, 2022Assignee: Graco Minnesota Inc.Inventors: John R. Ingebrand, Stanley G. Karwoski

Patent number: 10914304Abstract: A pneumatic timing valve includes a spool and seal system having a first seal cartridge and a spool. The first seal cartridge has an annular body with radial ports. The spool is positioned within the first seal cartridge and movable between a first and second position. The spool has a central bore and radial ports that intersect the central bore. The radial ports of the spool complement the radial ports of the seal cartridge. The seal cartridge radial ports, the spool radial ports, and the central bore of the spool define fluid flow passages.Type: GrantFiled: April 28, 2016Date of Patent: February 9, 2021Assignee: Graco Minnesota Inc.Inventors: Jacob K.
