Abstract
Abstract A retrofittable electric valve operating mechanism is provided which can be attached to an existing manual valve configuration while still allowing the manual feature of the valve to be utilized in two different manners. The configuration includes features which allow for certain misalignment of elements lying along the drive path, and can be installed without disturbing the existing plumbing associated with the valve.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
159 words
An apparatus for providing remote control of an otherwise manually operated valve with an existing handle including a hole, said valve providing selective flow to or from a plumbing member, said apparatus comprising: a drive unit itself comprising an electric motor; a handle engaging member attached to and rotatably driven by said drive unit, said handle engaging member including at least one elongate tong; and a substantially rigid framework configured to substantially rigidly interconnect said drive unit relative to said plumbing member, said framework including a drive unit mounting member configured to allow said drive unit to be moved along an axis between two positions, a first position in which said tong does not pass though said hole, and a second position in which said tong does pass through said hole, said drive unit configured to rotated said handle engaging member while in said second position such that said tong engages said handle and causes rotation of said handle.
Claim 2
Independent Claim
159 words
An apparatus for providing remote control of an otherwise manually operated valve with an existing handle including a hole, said valve providing selective flow to or from a plumbing member, said apparatus comprising: a drive unit itself comprising an electric motor; a handle engaging member attached to and rotatably driven by said drive unit, said handle engaging member including at least one elongate tong; and a substantially rigid framework configured to substantially rigidly interconnect said drive unit relative to said plumbing member, said framework including a drive unit mounting member configured to allow said drive unit to be moved along an axis between two positions, a first position in which said tong does not pass though said hole, and a second position in which said tong does pass through said hole, said drive unit configured to rotated said handle engaging member while in said second position such that said tong engages said handle and causes rotation of said handle.
Claim 3
Dependent Claim
22 words
The apparatus as claimed in claim 1, wherein said tong is substantially parallel to the rotational axis of the handle engaging member.
Claim 4
Independent Claim
132 words
An apparatus for providing remote control of an otherwise manually operated valve having a valve handle rotatable about a rotational handle axis, said apparatus comprising: a drive unit itself comprising an electric motor having a rotational output about a rotational drive axis; a sliding universal interconnection intermediate said drive member and said valve handle configured to accommodate misalignment of said rotational handle axis and said rotational handle axis; and a substantially rigid framework configured to substantially rigidly interconnect said drive unit relative to said plumbing member, said framework including a drive unit mounting member configured to allow said drive unit to be moved along an axis between two positions, a first position in which said sliding universal interconnection is disengaged, and a second position in which said sliding universal interconnection is engaged.
Claim 5
Independent Claim
132 words
An apparatus for providing remote control of an otherwise manually operated valve having a valve handle rotatable about a rotational handle axis, said apparatus comprising: a drive unit itself comprising an electric motor having a rotational output about a rotational drive axis; a sliding universal interconnection intermediate said drive member and said valve handle configured to accommodate misalignment of said rotational handle axis and said rotational handle axis; and a substantially rigid framework configured to substantially rigidly interconnect said drive unit relative to said plumbing member, said framework including a drive unit mounting member configured to allow said drive unit to be moved along an axis between two positions, a first position in which said sliding universal interconnection is disengaged, and a second position in which said sliding universal interconnection is engaged.
Claim 6
Dependent Claim
18 words
The apparatus as claimed in claim 3, wherein said sliding universal interconnection is provided by a pin/hole engagement.
