ABSTRACT:
A gear mechanism, of the Moineau type, having an outer gear member with a helical inner surface. The motor also has a helical inner gear member within the outer member. A resilient sleeve is located between the inner and outer gear members, and has helical inner and outer surfaces. The inner gear member has one less helical thread than the inner surface of the resilient sleeve. The outer surface of the resilient sleeve is similar to, but rotationally offset from, the inner surface of the resilient sleeve.
