Claim Text:
1. A bypass assembly for use in a downhole tool comprising: a chamber; a first fluid port in fluid communication with the chamber; a second fluid port in fluid communication with the chamber; a flow restrictor disposed in a first flow path between the first fluid port and the second fluid port; a piston disposed within the chamber and moveable in a first direction by the application of a first fluid pressure from the first fluid port; a biasing member, wherein the biasing member biases the piston to move in a second direction opposite the first direction; and a restraining member disposed adjacent to the piston, wherein the restraining member is actuated by movement of the piston in the first direction in response to the first fluid pressure; wherein the bypass assembly diverts fluid flow around the flow restrictor along a second flow path between the first fluid port and the second fluid port when the piston is actuated in the second direction to a second position.
