Abstract
1282435 Pistons; fluid bearings W A KATES Co 23 Oct 1969 [29 Oct 1968] 51989/69 Headings F2A and F2T Means for centering and minimizing friction between a cylindrical member (e.g. piston or shaft) operating with clearance in a bore in an outer member as a result of fluid flow through the clearance comprises an annular recess in one of the members which opens into the clearance and is in communication with the adjacent fluid pressure space by restricted flow means in addition to the clearance. A control piston 10, Fig. 1, operates with clearance 15 in a cylinder 12, the recess 17 being in communication with the higher pressure space 13 by means of radial holes 21, or alternatively, axial holes or grooves. The bottom end of the piston may be provided with a similar recess instead of, or as well as, the one at the top end in communication with the low pressure space 14. The shaft journal 210, Fig. 4, operates with a clearance 215 in an outer member 212, the recess 217 communicating with the pressure space by means of axial holes 221.
