ABSTRACT:
A novel pressurized fluid delivery system which has a single fluid inlet block for each plunger of a pump assembly and with an individual fluid inlet manifold and an individual fluid discharge manifold coupled by a valve body assembly to the fluid cylinder block. The three individual units, the fluid inlet manifold, the fluid outlet or discharge manifold, and the fluid cylinder block, are small in size and weight when compared to the single large fluid cylinder block of the prior art and thus are much less expensive to manufacture and are easier to handle. The novel valve assembly is less expensive to manufacture, has a lower restriction to fluid flow than prior art comparable valves and requires less suction feed pressure than the prior art valves.
