Abstract

A multi-piston pump includes a housing defining a first plurality of N bores therein, where N is the number of bores in the first plurality. The first plurality of N bores is offset from one another. The housing defines a second plurality of N bores therein. The second plurality of N bores is offset from one another. Each bore of the second plurality of N bores is offset from a corresponding bore of the first plurality of N bores. A non-stepped piston is disposed in each of said bores for reciprocal movement along a longitudinal axis therein. The pistons in the first plurality of N bores are operable to induce fluid flow in hydraulic fluid. The pistons in the second plurality
