Abstract
A displacement type fluid machine has a sliding contact portion between a cylinder 4 and a displacer 5 made into a predetermined section, and the cylinder and the displacer so contoured that when they are made concentric, the normal distance in the sliding contact section between the cylinder contour and the displacer contour may be smaller than that of the remaining section, thereby to decrease the radial gap to lower the internal leakage of the working fluid and to improve the performance and the reliability.
