Patent ID: 7296486

Claim:
A hydraulic motor drive sensor adapter, comprising: a. a motor body, further comprising a central channel disposed at least partially through an internal portion of the motor body, the central channel defining a central longitudinal axis; b. a disk valve rotatably mounted within a pre-determined portion of the motor body and in fluid communication with the central channel, the disk valve further comprising: i. a central port substantially aligned with the central channel; and ii. an outer port disposed about an outer circumference of the disk valve; c. a main shaft rotatably mounted at least partially within the central channel, the main shaft further comprising: i. a central axis which is not concentric with the central longitudinal axis; ii. an upper end loosely disposed at least partially within the central port such that movement of the upper end within the central port is limited in a predetermined plane; iii. a drive shaft receptacle positioned at the upper end; and iv. a lower end; d. a socket housing rotatably positioned about a constant axis within the motor body, the socket housing further comprising: i. a top surface; and ii. an internal chamber; e. a drive shaft, disposed within an upper portion of the central channel, the drive shaft further comprising: i. a lower region loosely mounted in the shaft receptacle such that movement of the lower region of the drive shaft within the shaft receptacle is limited in a predetermined plane; and ii. an upper region disposed opposite the lower region and loosely mounted within the internal chamber such that movement of the upper region of the drive shaft within the internal chamber is limited in a predetermined plane; and f. a magnet mounted on the top surface of the socket housing above the upper region of the drive shaft.
