Abstract
A multistage compressor has a yoke with a cross slider and roller bearings pressed against the sides of the cross slider by spring forces to enable the cross slider to slide smoothly within the yoke. The spring forces are generated by springs disposed between the yoke and a liner plate that urges the roller bearings against the cross slider. By this construction, the yoke and cross slider are not damaged during operation of the compressor even if the dimensions of the members change due to thermal expansion.
