A drive for driving a displacer in a cryogenic refrigerator includes a rotatable cam having a cam surface. The cam is rotatable about a pivot point with a cam follower contacting the cam surface. Rotational motion of the cam is converted into reciprocating motion of the cam follower. A displacer rod is coupled between the cam follower and the displacer for transferring the reciprocating motion of the cam follower to the displacer for driving the displacer.
