Claim 1
Independent Claim
214 words
A two-part metal housing for a rotary ball valve mechanism comprising a sheet metal main body part, including a first generally cylindrical portion, a second enlarged portion for enveloping the ball mechanism including a generally cylindrical wall and a radial shoulder interconnecting said cylindrical wall and said first portion, the junction of said shoulder and said first portion producing a seat support for the ball mechanism, and a third annular flange portion radially extending from said second portion and curled over to engage the mating section of the other part of the valve housing in which the metal grain is continuous and is aligned with the contour of said main body through all of its portions; and a sheet metal closure part, including a first generally cylindrical section, and a second flange section radially extending from said first section closing one end of said second portion of said main body part and extending into the curled flange of said third portion for completing the valve housing and producing a second seat support for the ball mechanism, in which the metal grain is continuous and is aligned with the contour of said closure part through all of its sections and an aperture in said second enlarged portion for a stem of the rotary ball mechanism.
