20130061932, Mar 14, 2013

Filed:

Sep 9, 2011

Appl. No.:

13/229029

Inventors:

Jason E. Rosner - Southington CT, US

International Classification:

F15D 1/00

US Classification:

137 1, 1374875

Abstract:

A hydraulic system, including fluid flow generated by a primary pump and a secondary pump, utilizes a regulator control assembly to control fluid flow from each of the primary and secondary pumps such that a desired fluid flow and pressure is maintained at the outlet for varying actuator demands. The regulator control assembly controls the transition from using only the primary pump, to using both the primary and secondary pumps to provide a desired fluid flow and pressure through the outlet to the actuator.

Abstract:

A modular multi-pump system is provided. The modular multi-pump system may comprise a plurality of modular pump systems. A modular pump system may comprise a pump, at least one backpressure orifice, a pressure regulating valve (PRV), and a mix valve. The pump may receive and pump a fluid through the modular multi-pump system. The at least one backpressure orifice may set a desired fluid output pressure for the fluid flow. The pressure regulating valve may maintain modular pump system fluid output pressure in response to being in a balanced position, and may initiate fluid flow transition to the next modular pump system in response to being in a transition position. The mix valve may prevent fluid flow from the next modular pump system in response to being in a first position, and enable fluid flow from the next modular pump system in response to being in a second position.
