Abstract:
1. An apparatus for actuating a valve, comprising: an input member, said input member being configured for receiving and engaging a driving mechanism; an output member, said output member being configured for receiving and engaging a valve stem; a lobe member, said lobe member positioned with respect to said input member such that the axis of said lobe member is parallel to, but centrally offset from the axis of said input member, wherein said lobe member is rotationally coupled with said input member such that said lobe member and said input member share the same rotational velocity and torque; a driver disc, wherein said driver disc is engaged with said input member through said lobe member, wherein said driver disc is axially aligned with said lobe member, wherein said driver disc moves about said input member in eccentric fashion at reduced speed with respect to said input member as a response to rotational force applied to said input member by said driving mechanism; a transferring member, said transferring member being engaged with said driver disc such that said transferring member rotates about said input member, said transferring member being axially aligned with and rotationally coupled to said output member such that said transferring member and said output member share the same rotational velocity and torque; and a stationary housing member, wherein said stationary housing member substantially covers said input member, said output member, said lobe member, said driver disc, and said transferring member, wherein said stationary housing member engages said driver disc, said stationary housing member being configured to remain fixed with respect to the surrounding environment of said apparatus.
