ABSTRACT:
A connection between a drive member and a driven member comprises a first nickel titanium alloy wire interconnecting the drive member and a rigid link and a second nickel titanium alloy wire connecting the rigid link and the drive member. Such a wire, when properly heat treated, has a high tensile and also a high compressive strength while at the same time the wire will bend readily if there is misalignment between the longitudinal movements of the drive and driven members. Thus the assembly functions as a two-ball joint drive line similar to that used in automobiles. A preferred usage is in driving the plunger of a syringe in a dosage metering system from a moving machine element where the syringe bore and direction of movement of the machine element may be slightly out of alignment. Wear of the syringe seals is reduced.
