Self-adjusting earth-boring tools and related systems
First Claim
1. An earth-boring tool, comprising:
- a movable component; and
an additive manufacturing formed flow control device in fluid communication with the movable component and configured to control a flowrate of the fluid through the additive manufacturing formed flow control device, wherein the additive manufacturing formed flow control device is configured to control a movement of the movable component via the flowrate of the fluid through the additive manufacturing formed flow control device, wherein the additive manufacturing formed flow control device comprises a body including at least one nonlinear fluid passage defined by at least partially superimposed gaps in adjacent layers of material of the body.

Abstract
An earth-boring tool includes a movable component and an additive manufacturing formed flow control device in fluid communication with the movable component and configured to control a flowrate of the hydraulic fluid through the additive manufacturing formed flow control device, wherein the additive manufacturing formed flow control device is configured to control a movement of the movable component via the flowrate of hydraulic fluid through the additive manufacturing formed flow control device. An earth-boring tool includes an additive manufacturing formed flow control device in fluid communication with one or more components of the earth-boring tool and configured to provide a cooling fluid to the one or more components of the earth-boring tool.
