US Patent:

7108116, Sep 19, 2006

Filed:

May 5, 2004

Appl. No.:

10/839379

Inventors:

Samuel R. Wynn - Marietta OH, US

Assignee:

Electronic Design for Industry, Inc. - Marietta OH

International Classification:

F16D 19/00

US Classification:

192 99S, 74 2, 192 83

Abstract:

A clutch actuating apparatus for engaging a clutch on an engine, such as an engine that drives an oil or gas well pump. The clutch actuator includes a first prime mover for rotating a clutch operating shaft in one direction toward a clutch-engaging position, but which unseats from driving the shaft after the shaft reaches the break over point and before engaging the clutch to prevent clutch damage. A second prime mover rotates the clutch operating shaft in the opposite direction toward a clutch-disengaging position, and unseats from driving the shaft after the break over point.

Appl. No.:

7/831107

Inventors:

Samuel R. Wynn - Marietta OH

International Classification:

E21B 4312
E21B 4706

US Classification:

166 53

Abstract:

Apparatus is disclosed for automatically operating a gas and oil producing well of the plunger lift type, including a comparator for comparing casing and tubing pressures, a device for opening the gas delivery valve when the difference between casing and tubing pressure is less than a selected minimum value, a device for closing the gas discharge valve when casing pressure falls below a selected casing bleed value, an arrival sensor switch for initially closing the fluid discharge valve when the plunger reaches the upper end of the tubing, and a device for reopening the fluid discharge valve at the end of a given downtime period in the event that the level of oil in the tubing produces a pressure difference greater than the given minimum differential value, and the casing pressure is greater than lift pressure. The gas discharge valve is closed if the pressure difference exceeds a selected maximum value, or if the casing pressure falls below a selected casing bleed value. The fluid discharge valve is closed if tubing pressure exceeds a maximum safe value.
