Abstract

565,805. Radial cylinder pumps. VICKERS-ARMSTRONGS, Ltd., HOLDEN, W. C., and NAYLOR, J. C. June 25, 1942, No. 8741. [Class 102 (i)] [Also in Group XXVI] In an eccentrically-driven radial cylinder hydraulic pump, the eccentric 18 slides over one or more plane surfaces at right angles to the axis of the driving shaft 4 by making that part 17 of the shaft of square, rectangular, or like cross-sectional shape, rollers or like antifrictional bearings being interposed between the plane surfaces on the shaft and the adjacent surfaces of the eccentric or of segmentalshaped blocks carried thereby. The eccentric may be operated against the action of coil springs 23, located within the shaft 4 or annular members carried thereby, by means of a ram 25 acted upon by the pressure fluid in the pump. The ram 25 may be hollow or of the differential type, and is supplied with pressure fluid by a hollow spring-pressed floating ram 30 located within the driving shaft 4 and connected to the pump delivery 12. The shaft 4 also carries a rotor 8 for circulating the fluid to and from a tank when the pump is stalled, and a selfseating valve 9 as described in Specification 503,148. The pistons 2 may be of the kind described in Specification 565,334. Fig. 7 shows a modification in which the eccentricoperating. ram comprises two parts 25 of different diameter, the larger being adjustable by a screw 41 in a projection 42 on the eccentric 18, access to this screw, and to screws for adjusting the springs 23, being given by means of a sight opening 40a.
