摘要： A ball valve is produced, which has a valve housing 10 and a ball 20. A pair of mirror-symmetrical housing halves 12, 14 are jointed together along a single weld line. The housing halves are jointed together by welding in a manner to enclose the ball previously provided with a through bore and a pair of recessed portions. The through bore 22 of the ball is arranged to be in conformity with the weld line. Holes 42, 50 for respectively mounting a pair of stem assemblies are formed by machining respectively in those portions of the valve housing opposed respectively to open opposite ends of the through bore. The centers of the holes are in alignment with the operational centerline of the ball valve. The ball is turned by an angle of 90 degrees, thereby bringing the through bore of the ball into alignment with openings 12A, 14A of the valve housing, and the recessed portions 26, 28 of the ball are brought into alignment with the holes, respectively. Next, the pair of stem assemblies 60, 68 are attached to the both holes, respectively, and stems are fitted in the both recessed portions, respectively, and the pair of stems are welded circumferentially to peripheral edge portions of the holes, respectively.

摘要： A valve stem installation system includes a robotic arm for moving a valve stem insertion device around the lip of wheel. The system also includes a pair of valve stem aperture sensors positioned on the robotic arm adjacent the valve stem insertion device and moveable around the lip of the wheel. The sensors can be positioned on opposite sides of the valve stem insertion device. When the first sensor locates the valve stem aperture, movement of the robotic arm can be slowed. When the second sensor locates the valve stem aperture, movement of the robotic arm can be stopped. The conveyor unit can include an identification station to sense the configuration of the wheel. A controller can select the appropriate valve stem to insert in the valve stem aperture in response to the sensed configuration of the wheel.

摘要： A method for producing longitudinally welded helically corrugated metal tubing, wherein a metal strip pulled from a strip supply is formed into tubing with a longitudinal slit, the longitudinal slit is sealed by welding and the corrugation is produced by a corrugation tool that is supported eccentrically and at an angle to the tubing axis, is freely rotatable in a rotationally driven corrugator head, and rolls off the surface of the tubing. The metal strip as well as the uncorrugated metal tubing are advanced by a feed device that is provided between the welding point and the corrugation unit. A second feed device (8) engages the corrugated tubing (7) directly behind the corrugation unit (6), and the feed rate of the second feed device is slower than the forward feed rate of the corrugated tubing (7) which results from the pitch of the corrugator disk and the rotational speed of the corrugator head.

摘要： A valve stem seal assembly includes a retainer with one or more built-in sprues, a cavity at one end, an annular flange on the opposite end, and a cylindrical interior passageway therebetween. The built-in sprues extend from the bottom surface of the cavity to the annular flange. The valve stem seal assembly also includes a jacket made of an elastomeric material integrally bonded to the retainer. When the valve stem seal assembly is fitted atop the valve guide, a gap is formed between the bottom surface of the cavity of the retainer and the top surface of the valve guide to accommodate manufacturing tolerances in the height of the valve guide. The jacket is integrally bonded to the retainer by introducing material into the cavity, through the built-in sprues, and out of the bottom of the annular flange. One preferred method of manufacturing the valve stem seal assembly provides placing the retainer atop a tool plate that contains a circumferential groove, positioning the retainer to properly receive an elastomeric material, pouring the elastomeric material through the built-in sprues forming the jacket and curing the elastomeric material until the jacket is bonded with the retainer. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

摘要： An improved method for partially assembling a fuel injector comprising the steps of providing a fixture for receiving a guide disk having a guide opening and a valve seat having a ball seat; inserting the guide disk and valve seat into the fixture; providing a locating tool including a locating ball; extending the locating ball through the guide opening and seating the ball into the ball seat to displace the guide disk and valve seat into coaxial alignment with the locating tool, thereby aligning the opening of the guide disk with the ball seat of the valve seat; loading the valve seat and guide disk axially against a receiving surface of the fixture; welding the valve seat to the guide disk to form a coaxially-aligned valve seat and guide disk sub-assembly; removing the sub-assembly from the fixture; inserting the sub-assembly into a recess in a fuel injector valve body; and crimping an edge of the recess to retain the sub-assembly in the recess. The sub-assembly may be tested for coaxiality of the valve seat and guide disk or may be otherwise qualified as desired prior to insertion into the fuel injector valve body.
