Patent number: 9915367Abstract: A valve assembly includes a valve housing having an internal generally cup-shaped bore, a valve control cartridge inserted into the bore and having a rotatable control stem extending upwardly therefrom, and a bonnet nut having a through-bore. The bonnet nut is threaded to the valve housing such that the control stem extends through the through-bore. Flexible fingers are provided along the through-bore to control a level of resistance to a rotation of the rotatable control stem. The stem is positioned to frictionally engage the flexible fingers as the stem is rotated.Type: GrantFiled: September 21, 2016Date of Patent: March 13, 2018Assignee: KOHLER CO.Inventors: David H.

Patent number: 9874287Abstract: A service valve for a valve body includes a base rotatable between an open orientation and a closed orientation relative to the valve body. When the base is in the open orientation, the service valve allows fluid flow into the valve body through the service valve. When the base is in the closed orientation, the service valve blocks the fluid flow into the valve body through the service valve. The service valve further includes a tab extending from the base. The tab prevents removal of a cover from the valve body when the base is in the open orientation.Type: GrantFiled: June 2, 2015Date of Patent: January 23, 2018Assignee: KOHLER CO.Inventors: Douglas J. Brouwer, Michael W. Smith, Michael A. Niver, Chad J. Cochart

Patent number: 9816637Abstract: A testing cap for a valve body includes a base configured to releasably attach to the valve body and to cover an opening in the valve body. The opening is configured to receive a valve cartridge and the base covers the opening in place of the valve cartridge. The testing cap includes a structure extending from the base. The structure is configured to be oriented relative to the valve body in a first orientation and a second orientation. The structure allows fluid to enter the valve body through an inlet port in the valve body and exit the valve body through an outlet port in the valve body when the structure is oriented in the first orientation. The structure covers at least one of the inlet port and the outlet port when the structure is oriented in the second orientation, thereby preventing fluid flow through the valve body.Type: GrantFiled: June 2, 2015Date of Patent: November 14, 2017Assignee: KOHLER CO.Inventors: Douglas J. Brouwer, Michael W. Smith, Michael A. Niver, Chad J. Cochart

Patent number: 9657874Abstract: A coupling system for interconnecting a tube to a valve body is provided. The valve body has a body portion and a nipple extending from the body portion, and the nipple has a threaded external surface and an internal wall defining a bore. The coupling system further includes an adapter having opposing first and second ends, a nut defining a hole through which the first end passes, and a compression fitting located between the nipple, the adapter, and the nut such that when the nut is tightened onto the nipple, the compression fitting inhibits removal of the adapter from the valve body. The adapter defines a passageway extending from the first end to the second end, wherein the first end is received in the bore and the second end is configured to couple to the tube. The nut has an internally threaded surface configured to engage the threaded external surface.Type: GrantFiled: April 24, 2015Date of Patent: May 23, 2017Assignee: KOHLER CO.Inventors: Douglas J.

Patent number: 9334971Abstract: A universal valve body includes a front face having a circular opening for receiving a valve cartridge, a rear face, a frustoconical side wall connecting the front face to the rear face, and a first inlet port and a first outlet port obliquely disposed in the frustoconical side wall. A cap for the valve body includes a base and a structure extending from the base. The structure extending from the base may block at least one of the inlet port or outlet port in the valve body. A service valve for a valve body includes a base rotatable between an open orientation and a closed orientation relative to the valve body and a tab extending from the base. When the base is in the open orientation, the tab prevents removal of a cover from the valve body.Type: GrantFiled: March 13, 2013Date of Patent: May 10, 2016Assignee: KOHLER CO.Inventors: Douglas J.

Patent number: 9182045Abstract: A diverter cartridge for a fluid mixing valve includes an inlet adapter having a first inlet port, a second inlet port, a first outlet port and a second outlet port. The cartridge further includes a diverter plate having a first inlet channel and a second inlet channel. The diverter plate is rotatable relative to the inlet adapter between a first end position, a second end position, and a neutral position between the first and second end positions. Rotation of the diverter plate from the neutral position toward the first end position increases a volume flow rate through the cartridge and diverts the fluid to the first outlet port. Rotation of the diverter plate from the neutral position toward the second end position increases a volume flow rate through the cartridge and diverts the fluid to the second outlet port.Type: GrantFiled: March 13, 2013Date of Patent: November 10, 2015Assignee: KOHLER CO.Inventors: Douglas J.
