| description | A production plunger is disclosed that will automatically reciprocate in the production string of a producing oil well that is also producing some gas. The plunger includes a body having a passageway that allows fluid to bypass the packer cups carried by the body. A valve in the passageway is held open by a bellows filled with air under pressure. The valve is closed by the pressure of the liquid accumulated above the plunger at which time, the gas produced by the well will lift the plunger and the liquid above it to the surface. |
