ABSTRACT:
A fluid transducer including a reciprocatory piston member and a rotary member, and a drive mechanism for converting reciprocation of the piston member into rotation of said rotary member, or vice versa. The drive mechanism includes a first elliptical member rotatable with said rotary member and a second elliptical member rotatably mounted within said transducer and arranged for reciprocation with said piston member. The elliptical members are retained in engagement, and rotate in unison as said piston member reciprocates with respect to said rotary member to transmit motion between said piston and rotary members.
