Abstract
A control valve assembly for the rotary or linear actuation of control valves using contactless technology and the use of direct integration of electronic componentry into a lead frame interconnection assembly includes a contactless motor, a control valve in mechanical communication with the contactless motor through a gear system, and a lead frame interconnection assembly having electronic componentry relevant to the contactless motor and the control valve integrally formed therein. The contactless motor includes a commutator magnet disposed on a rotor shaft thereof. The commutator magnet is in magnetic communication with at least two commutator chips integrally formed with the lead frame interconnection assembly. The control valve includes a throttle element disposed in a throttle bore, an output shaft depending from the throttle element, and at least one position sensing magnet disposed on an end of the output shaft distal from the throttle element. The position sensing magnet is in magnetic communication with at least one position sensor integrally formed with the lead frame interconnection assembly. The throttle element may be a throttle plate rotatably positioned within the throttle bore, or it may be a linearly translatable device.
