Abstract

824,152. Reciprocating pumps. GIANNELLI, G. Jan. 21, 1958, No. 1989/58. Class 102(1). The eccentric of a radial cylinder pump is automatically controlled by the load on the pump to vary the stroke of the pistons. The eccentric 15 is connected by a pin 17 to a yoke 13a secured to the drive shaft 13 which has a surface engagable with a fixed stop 19 secured to the eccentric and defining the maximum eccentricity and another surface engaged by a spring loaded member 21 slidable in a guide 20 carried by the eccentric 15. As the load in the pump increases the spring loading is overcome and the eccentricity is decreased. In a modification the spring and member 21 is replaced by a piston hydraulically connected to an external spring. In a further embodiment two eccentrics of opposite eccentricity operate pistons disposed in parallel radial planes.
