  • Patent number: 8535024
    Abstract: A downhole pump has a barrel and plunger. The barrel has a first one-way valve and the plunger has a second done-way valve. The plunger reciprocates with respect to the barrel. The plunger has a first end which has a tapered leading edge. Ports are adjacent to the leading edge. The ports communicate with a passage in the plunger. A sucker rod string coupling is located at the plunger first end. The sucker rod string coupling is coupled to walls located between the ports. The end of the sucker rod string coupling that is coupled to the plunger is tapered so that fluid can flow out of the ports. The sucker rod string coupling and the plunger first end form an integral member that couples to the remainder of the plunger.
