ABSTRACT:
A pump system for high pressure hydraulic applications. A series of longitudinally spaced single acting pumps are sequentially actuated by rolling heavy weights that are moved about an endless upright track assembly by gravity assisted by operation of a prime mover. The track assembly includes an elongated inclined ramp, a horizontal base, and a relatively steep return arranged in a triangular supporting structure for an endless conveyor. The conveyor mounts a plurality of longitudinally spaced weight assemblies, which are arranged transversely between supporting endless chains. A series of pumps are mounted on the frame in fixed positions with their single acting actuators in the path of elements moved in unison with the conveyor. The pumps are preferably spaced apart a distance substantially less than the spacing between the weight assemblies and the spacing between adjacent weight assemblies is preferably not an even multiple of the spacing between the pump mechanisms.
