Patent ID: 7651428

Claim:
A device for actuating a reciprocating recovery means for recovery of underground fluid, comprising: an input component, where said input component is configured for receiving and engaging a driving mechanism; one or more lobes, where a lobe is adjacently positioned with respect to said input component, where each lobe is axially aligned, but centrally offset, from said input component and an output component, and each lobe being rotationally coupled with said input component so that each lobe and said input component share the same rotational speed; one or more driver discs, said driver discs being engaged with said input component through a corresponding lobe, wherein each disc is centrally, axially aligned about a corresponding lobe, where each disc moves about said input component in eccentric fashion with reduced speed, responding to rotational force applied to said input component by said driving mechanism via said corresponding lobes; one or more take off members, said take off members engaged with a corresponding driver disc such that each rotates about said input components with the same speed, where each take off member is centrally, axially aligned with said output component and rotationally coupled with such so that each take off member and said output component share the same reduced rotational velocity; a housing; where said housing substantially covers said input component, said output component, said lobes, said driver discs, and said take off members, where said housing is engaged with said take off members and said driver discs such that each may freely rotate within said housing, and where said housing is configured to remain fixed with respect to the surrounding environment of said device.
