Throttle position sensor adapted to maintain a fixed position relative to a shaft centerline

A device for determining the position of a rotatable member, comprising:

• means for causing a magnetic field to rotate with said rotatable member, said rotatable member being rotatable relative to a housing structure;
• a magnetically sensitive device disposed in a carrier assembly within effective range of said causing means to sense a magnitude of said magnetic field in a predetermined direction, said carrier assembly having a portion shaped to receive said rotatable member in rotatable and sliding association therein, said magnetically sensitive device having an output for providing a signal representative of the effective strength of said magnetic field imposed on said magnetically sensitive device;
• pivot means, attached to said housing structure and to said carrier assembly, for permitting said carrier assemble to rotate about a point on said housing structure;
• and
• means, in contact with said carrier assembly, for urging said carrier assembly against said rotatable member.

A device for determining the position of a rotatable member, comprising:

• a magnet attached to said rotatable member;
• a magnetically sensitive device;
• a carrier assembly having a portion shaped to receive said rotatable member in sliding contact therewith, said rotatable member being rotatable relative to said carrier assembly, said magnetically sensitive device being disposed within said carrier assembly, said portion being disposed in contact with said rotatable member, said rotatable member being attached in rotating association to a housing structure;
• a pivot arm attached in rotating association with said carrier assembly and with said housing structure;
• and
• a resilient member attached to said carrier assembly and to said housing structure to urge said carrier assembly against said rotatable member.
