Description

[0001] related application [0001] This application is filed as a non-provisional patent application claiming priority and any other benefit to U.S. Provisional Patent Application No. 60 / 898,542, filed January 31, 2007, under 35 U.S.C. § 119(e), the entirety of which is adopted by References are included here. technical field [0002] The present invention relates generally to spools and, more particularly, to spools having low contact points for mounting the spool in a valve body. Background technique [0003] Typically, for a plumbing fixture (eg, faucet, tub spout, shower head), the valve body conveys water flowing from a main water source to a desired destination (eg, sink, tub, washbasin). The valve body usually has two water inlet passages through which cold water and hot water from the main water source can flow respectively. The valve body also has a water outlet passage through which cold water, hot water, or a mixture of cold and hot water can be discharged to ...

Problems solved by technology

[0018] However, taller mounting lugs 146 have several disadvantages

For example, the taller mounting lug 146 results in less freedom in the design of the plumbing fixture for receiving the spool 200

In addition, taller mounting lugs 146 result in increased cost because the height of the sidewall 150 of the valve body 140 is typically at least as high as the height of the mounting lugs 140
