A fluid transducer including a reciprocatory piston member and a drive mechanism for converting reciprocation of the piston member into rotation of a rotary member coupled to the mechanism, or vice versa. The drive mechanism includes a first elliptical member centrally mounted within said transducer and a second elliptical member rotatably mounted in engagement with said first member and arranged for reciprocation with said piston member. As said piston member reciprocates said second member rotates with respect to said first member to transmit motion between said piston and said rotary member coupled to the drive mechanism.
