Adjustable flow-synchronization return valve for hydraulic pressure balancing

A flow-synchronization return (FSR) valve consisting of:

• a base comprising an inner threaded ring;
• a valve element consisting of a bolt, wherein the bolt comprises:
• a) a threaded portion;
• b) a shank portion with no threads;
• and
• c) a bolt head comprising a first surface;
• and
• a body comprising:
• a) a second surface;
• and
• at least one restriction gap stop;
• wherein the flow rate of a fluid through the FSR valve is based, in part, on a separation distance between the first surface and the second surface;
• and
• wherein the threaded portion is configured to engage the threaded ring when the first surface and the second surface are not in contact, and the threaded portion is configured to disengage the threaded ring when the first surface and the second surface are in contact, wherein the flow rate of the fluid through the FSR valve can be synchronized with one or more additional FSR valves.

A flow-synchronization return (FSR) valve comprising:

• a base comprising a threaded ring;
• a valve element comprising:
• a) a threaded shaft configured to engage the threaded ring;
• and
• b) a first surface;
• a body comprising:
• a) a second surface characterized by a conical shape;
• and
• b) at least one restriction gap stop protruding from the second surface;
• and
• a housing, wherein the body is configured to swivel within the housing;
• wherein the flow rate of a fluid through the FSR valve is based, in part, on the separation distance between the first surface and the second surface;
• and
• wherein the at least one restriction gap stop is configured to prevent the first surface from contacting the second surface and to direct water through the valve and out of the valve in a direction perpendicular to the body, wherein the flow rate of the fluid through the FSR valve can be synchronized with one or more additional FSR valves.

A flow-synchronization return (FSR) valve consisting of:

• a base comprising:
• a) an inner threaded ring;
• b) an outer ring;
• and
• c) a plurality of spokes connecting the inner threaded ring to the outer ring;
• a valve element consisting of a bolt, wherein the bolt comprises:
• a) a threaded shaft configured to engage the threaded ring;
• and
• b) a bolt head comprising a first surface;
• and
• a body comprising:
• a) a second surface;
• and
• at least one restriction gap stop;
• wherein the flow rate of a fluid through the FSR valve is based, in part, on a separation distance between the first surface and the second surface;
• and
• wherein the at least one restriction gap stop is configured to prevent the first surface from contacting the second surface;
• wherein the at least one restriction gap stop is integral to, and protrudes from, the first surface;
• wherein the flow rate of the fluid through the FSR valve can be synchronized with one or more additional FSR valves.
