摘要： A bypass plunger includes a unitary or one-piece hollow body-and-valve cage, which retains a dart valve within the valve cage portion of the hollow body using a threaded retaining nut that is secured to the hollow body by crimple detents. A series of helical grooves surround the central portion of the outer surface of the hollow body of the plunger to control spin during descent. A canted-coil-spring disposed within the retaining nut functions as a clutch. The valve cage includes ports that may be configured to control flow through the plunger during ascent.

摘要： A bypass plunger includes a unibody, or one-piece hollow body and valve cage, retains a dart valve within the valve cage portion using a threaded retaining nut secured by crimple detents, and includes sealable flow parts. A series of helical grooves surround the central portion of the outer surface of the hollow body of the plunger to control spin during descent. A canted-coil-spring disposed within the retaining nut functions as a clutch. The valve cage includes ports that may be configured to control flow through the plunger during descent. Other embodiments include clutch assemblies using canted-coil springs with split bobbins, and surfaced valve stems surfaced.

摘要： A bypass plunger formed as an integral one-piece hollow body-and-valve cage unit retains a dart valve within a valve cage section of the hollow body with a threaded retaining nut that may be secured by crimple means. A boundary zone, defined along the plunger body, where the integral valve cage section adjoins the plunger body, is configured with a uniform outer diameter to maximize the plunger body wall thickness and durability of the one-piece bypass plunger. The valve cage may have flow ports configured with ramps at an angle with the longitudinal axis to control flow through the flow ports during descent of the bypass plunger. A clutch assembly using garter springs with split bobbins may be disposed within the valve cage portion of the one-piece bypass plunger.

摘要： An improved latch structure for a two piece ball and sleeve bypass plunger comprises a single retaining ring installed in a groove formed in the inside diameter of the sleeve portion of the bypass plunger. The cross section profiles of the groove and the associated retaining ring are smaller in the radial direction. The depth of the groove in the sleeve is substantially reduced to provide increased wall thickness and robustness of the sleeve along the diameter of the sleeve, thereby extending the useful life of the bypass plunger.

摘要： A minimum parts bypass plunger includes a main shaft or pushrod extending through a hollow plunger body that incorporates flow passages formed in the adjacent surfaces of the pushrod or the internal bore of the plunger body. The pushrod is retained within the plunger body by respective head and tail pieces or caps that are locked to the plunger body by 360 degree crimps around the head and tail pieces. A one piece clutch is supported in the head piece. The pushrod, has an integral valve head that closes the flow passages when seated against a seat in the plunger body.

摘要： A method for locking an internally threaded end piece such as a head piece, a tail piece, an end or sealing nut to a mandrel for a down hole tool to obviate the need for pins, set screws, and the like, to provide a more robust assembly. In two embodiments the threaded end piece is locked to the mandrel in a swaging operation.

摘要： A dart valve assembly includes a dart valve and a clutch that restrains the movement of the dart valve within the bore of a dart valve cage or plunger body between a closed and an open position. The clutch includes a clutch bobbin formed of a synthetic material, and both the inside diameter of the clutch bobbin and the outside diameter of the dart valve stem of the dart valve assembly are configured with a sequence of alternating ridges and grooves to improve clutch action through reduced friction.

摘要： A unitary wellhead flow block lubricator assembly includes a unitary body and flow passageways that extend through the unitary body. Various openings on the exterior of the unitary body allow flow control devices to be mounted in the flow passageways to control the flow of fluid though the flow passageways. One or more of the control devices could be mountable in two or more orientations that alter the way in which the flow control device controls flow through one or more passageways in the unitary body. One or more choke mechanisms may also be mounted on the unitary body. The choke mechanisms may allow an operator to selectively adjust a flow of fluid through one or more of the passageways in the unitary body.
