The invention is an improved valve mechanism for controlling the flow in conduit to be used in combination with an adjustable valve. The adjustable valve includes a T-shaped valve body having a first bore extending therethrough and a second bore adjacent to the first bore. The adjustable valve also includes a stem having an inner end and an axially outer end which extends through one of the ends of the first bore and a device for forming a seal between the first bore and the stem. The valve mechanism includes a cylindrically shaped sealing member having a bore axially aligned with the first bore of the valve body and being disposed within the first bore adjacent to the end thereof oppositely disposed from the stem. The sealing member has a cylindrical inner sidewall and a truncated-conical outer sidewall adjacent to its top portion and a cylindrical outer sidewall adjacent to its bottom portion. The valve mechanism also includes a cylindrically shaped valve member which is adapted to slideably engage around the outer cylindrical sidewall of the sealing member and which is mechanically coupled to the stem so that its inner sidewall may travel along and adjacent to the outer sidewall of the sealing member.

An improved valve mechanism for controlling the flow in a conduit to be used in combination with an adjustable valve which includes: a. a valve body having a first bore with a first open end and a second open end extending therethrough, the valve also having a second bore with a first open end and a second open end adjacent to and perpendicular to the first bore, the second bore has its transverse axis axially aligned with the radius of the first bore, the first open end of the second bore functions as an inlet and is mechanically coupled to the conduit and the second open end of the first bore functions as an outlet and is mechanically coupled to the conduit; b. a stem having an inner end and an axially outer end which extends through the first open end of the first bore; and c. a device forming a seal between the first open end of the first bore and the stem, said improved valve mechanism comprising: a. a cylindrical sealing member having a bore axially aligned with the first bore of the valve body, said cylindrical sealing member being slideably engaged within the first bore of the valve body adjacent to the second open end thereof, said cylindrical sealing member having a cylindrical inner sidewall and a truncated-conical outer sidewall adjacent to its top portion and a cylindrical outer sidewall adjacent to its bottom portion; b. a cylindrical valve member which is adapted to slideably engage around said outer cylindrical sidewall of said sealing member, which is mechanically coupled to the stem so that its inner sidewall may travel adjacent to and along said outer sidewall of said sealing member, whereby the flow travels between said truncated-conical outer sidewall of said cylindrical sealing member and said inner sidewall of said cylindrical valve member in order that the flow may impinge upon itself; and c. sealing means for forming a seal between said sealing member and the first bore of the valve body, wherein said sealing means is a compressible and resilient member which is mechanically pressed against the inner sidewall of the first bore of the valve body when said cylindrical valve member presses down against the top of said cylindrical sealing member in order to mechanically set said sealing means thereby providing a tight seal.
