Abstract
A downhole tool includes a body defining a bore axially therethrough and a port in communication with the bore and extending radially through the body, an inner cap positioned in the port, the inner cap sealing the port, and an outer cap positioned in the port. The outer cap is spaced apart from the inner cap, and the outer cap seals the port, such that a chamber is defined between the inner and outer caps in the port. The inner cap is configured to move toward outer cap in response to a first pressure differential between bore and the chamber across the outer cap. The inner cap is configured to dislodge the outer cap from the port in response to the inner cap engaging the outer cap and a second pressure differential between the bore and an exterior of the downhole tool being reached across the inner cap.
