ABSTRACT:
A gas expansion engine in a refrigerating cycle is disclosed and, in particular, a gas expansion engine is provided which includes a cylinder and piston to define a variable-capacity expansion chamber therebetween. The piston is reciprocably inserted into the cylinder and is coupled to a motion conversion mechanism through a piston rod. One ball-and-socket joint is provided at at least one of a location between the piston rod and the piston and a location between the piston rod and the motion conversion mechanism. A ball-and-socket joint comprises a first member having a spherical convex surface section, a second member having a spherically concave surface section fitted into the spherically convex surface section of the first member and providing a joint boundary area with the first member, a slide mechanism for slidably moving the first member or second member in a direction perpendicular to the axis of the piston in accordance with an outer force, and an elastic member for providing a pressure contact force on an area between the spherically convex surface section and the spherically concave surface section.
