Abstract
252,438. Stern, W. J. Feb. 23, 1925. Fixed-abutment type. - In a rotary pump with sliding rocking-vanes rotating about a fixed centric lay shaft, one end of the lay shaft has an eccentric provided with a ball bearing which engages the rotor to support, the lay shaft. The bearing may be internal or external to the eccentric, and the other end of the lay shaft may be similarly supported. The vanes may be fitted with thrust members as described in Specification 244,181. The lay shaft o is carried by a stub shaft l and has an eccentric disc p for a ball bearing r, the inner race being fixed upon a stub k of the rotor shaft g. The shaft o carries bearings s for a sleeve u provided with separate rings v to which are secured the thrust members x of the vanes i. One of the vanes may be fixed to the sleeve. The vanes j are riveted to a channel. bar 2 expanded at intervals to engage dovetail recesses in appropriate rings v which may be counterbalanced. The end disc d<1> of the rotor e is carried by a bearing n around the stub shaft l. In a modification or a smaller machine, the vanes are secured to central arcuate blocks retained by sleeves mounted on the lay shaft. The lay shaft o may be straight and the stub shaft l dispensed with, and the disc d<1> is then carried by an eccentric bearing around the lay shaft. Each ring v may be provided with a ball bearing around the lay shaft. The trunnions blocks i may be mounted in ball bearings in the rotor and may have end recesses for thrust balls, and they may carry ball bearings for the vanes.
