  • Publication number: 20150184757
    Abstract: 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.

  • Patent number: 8800962
    Abstract: A valve assembly is provided. The valve assembly includes a valve housing and a harbor provided at a lower portion of the valve housing. The valve housing has an internal bore for receiving a valve control cartridge, and the harbor has a first recess suitable for receiving a water supply tube, and a second recess suitable for receiving a second water tube, wherein the harbor also has a slot. The valve assembly further includes the water supply tube mounted in the first recess, the second water tube mounted in the second recess, and a retainer clip positioned in the slot with that clip simultaneously engaging both tubes. The retainer clip comprises a first leg and a second leg connected by a waist to define there between a retaining area, and at least the first leg has formed thereon a notch adjacent a heel of the leg.

  • Patent number: 8297305
    Abstract: A valve assembly is disclosed providing a disk valve, a retaining clip configuration, and a bonnet nut. The disk valve comprises a moveable disk having a pair of recesses that is rotatable relative to a stationary disk to regulate the flow of a fluid through two ports in communication with the disks. The retaining clip configuration comprises a hose clip engaging a retaining segment on a valve housing and two hoses to connect the two hoses to two ports on the valve housing. The bonnet nut provides a tactile resistance to an applied torque when a portion of the valve cartridge assembly is rotated in relation to the valve housing.

  • Patent number: 8079381
    Abstract: A handle assembly is disclosed that is suitable for mounting a valve housing that has a valve stem to a support. In one form, the handle assembly includes a handle, an escutcheon, a bonnet, a recess, and a flexible snap ring. The handle is operationally linked to the valve stem of the valve housing for controlling movement of the valve stem. The escutcheon is positionable on a first side of the support adjacent the handle. The bonnet is linked to the valve housing. The recess is formed in one of the bonnet and escutcheon. The flexible snap member mounted to the other of the bonnet and escutcheon and suitable to snap into the recess when the bonnet and escutcheon are telescoped together, while thereafter permitting relative rotation of the bonnet and escutcheon.

  • Patent number: 7396283
    Abstract: A ball assembly (118) for a tripot-style joint includes an annular outer ball (124) having a central axis (L) extending therethrough and a depression (182) formed therein. A plurality of needle rollers (122) is positioned along an interior of the outer ball (124). A needle roller retainer (140) is provided for retaining the needle rollers (122) within the outer ball (124) during operation of the ball assembly (118). The retainer (140) has a base portion (142) axially opposed to an end portion (121) of the needle roller (122), and a flange portion (144) extending from the base portion (142) into the depression (182), the flange portion (144) of the retainer (140) being resiliently pivotable within the depression (182) in response to application of an axial load to the retainer (140). In a particular embodiment, an inner ball (120) is positioned in the interior of the outer ball (124f), and a series of resilient tabs (148f) extends from the base portion (142f) of the retainer (140f).
