Abstract
A latching solenoid has a first inductive coil for selectively positioning a member at a preselected location where it is locked against longitudinal movement by a mechanical latching means. The latching means includes a plunger moveable within a bore and positionable within a bifurcated end portion of the member. Inserting the plunger into the member radially expands the bifurcated end portion, capturing the end portion between the plunger and bore wall. A second inductive coil selectively withdraws the plunger from the bifurcated end portion, releasing the member from the latched position. Each of the coils is required to be energized only momentarily, thereby avoiding problems associated with constantly energized solenoids (e.g. heat dissipation, life expectancy, size, etc.).
