Abstract
Abstract An improvement in a method of forming a multi-way valve porting block for a mixing valve having a control head and respective conduits for hot water, cold water and controlled water characterized by the steps of: cutting off a predetermined thickness of a metallic bar stock having the desired cross sectional shape with a plurality of arms extending radially outwardly at 90* angles from a central point to form a solid block of the desired shape; and, thereafter, forming by machining respective large bores and smaller apertures in the respective conduits. The bar stock may have a Tee-shaped cross section or a cross-shaped cross section for respective three-way and four-way valve porting blocks, such as for tub alone or both tub and shower. Also disclosed are specific approaches to forming an aspirating passageway and aperture in the arm that will be connected with the tub or the like to prevent water from undesirably flowing upwardly and out of a shower, as well as the respective types of machining operations and preferred structural forms.

A method of forming a four-way valve porting block for a mixing valve having a control head and respective conduits for, respectively, hot and cold water from a source and controlled water to one of a tub and shower comprising the steps of: a. cutting off a predetermined thickness of a four-way metallic bar stock having a cross sectional shape in the form of a cross with two laterally extending arms and two aligned perpendicular arms extending normal to said laterally extending arms to form a solid cross shaped block with four respective arms; b. forming by machining a first large bore in each of said four arms for conformingly and sealingly receiving respective large conduits carrying the respective waters; c. forming by machining a first smaller bore extending longitudinally of said two perpendicular arms and communicating with the respective first large bores formed therewithin; one arm being adapted for connection with conduit leading to a shower and the other arm being adapted for connection with conduit leading to a tub; d. forming by machining two smaller apertures extending laterally throUgh one side wall of said cross shaped block and communicating, respectively, with each of said first large bores in said laterally extending arms; said smaller apertures being adapted for being connected with smaller conduits to the control head; and e. forming an aspirating passageway extending through said side wall and in communication with said first large bore in said other arm, of said two perpendicular arms, for being installed pointing downwardly and connected with said conduit leading to said tub; said aspirating passageway being adapted for being connected with a smaller conduit from the control head and terminating in an aspirating aperture near the center of said first large bore of said other arm, said aspirating passageway being formed by drilling two intersecting third and fourth bores.
