The new type restrictor of hydrostatic bearing has many good and useful restrictive performances： ①According to the analysis in this paper, the restrictive parameter index must be preserved b≥3.② When extra load forced on the bearing fluid pocket, the pocket pressure is increased by the additional load at once. At this time, the pocket pressure is applied to the end area of valve also. Therefore, the valve will be changed along axis by the increased fluid pressure. The incremental value of restrictive parameter will be increased at the same time. As a result, the new type restrictor will be supplied with more fluid flow. The bearing clearance may maintain nearly constant. ③There are three new types of restrictors： new type variable clearance slide valve, new type clearance sheat and new type variable diameter capillary. It has advantages, such as simple construction, low cost and smaller volume.
