Abstract:
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.

Claim (Index 1):
A bypass plunger, comprising: a monolithic hollow plunger body and valve cage having first and second ends; the valve cage forming the second end and including at least one flow port; a dart valve reciprocatingly disposed within the valve cage and having a valve head connected to a valve stem; and at least one plug located within a respective one of the at least one flow port and configured to reduce or prevent flow through the respective flow port;\n wherein the valve head includes a sealing face located on an end of the valve head that is opposite the valve stem and configured to seat against a valve seat of the valve cage.
