Abstract:
A valve assembly includes a piston housing inside a flow duct between an inlet and an outlet so as to form an annular flow passage between the flow duct and the piston housing. The piston housing is axially aligned with a center axis of the flow duct. A piston is inside the piston housing and is configured to extend downstream of the piston housing in a closed position. A spring biases the piston to the open position. A fluid chamber is between the piston and an upstream end of the piston housing. A control opening extends through the upstream end of the piston housing and fluidically communicates with the flow duct and the fluid chamber. A control piston and a control spring are inside the piston housing. The control spring biases the control piston toward a first position that obstructs the control opening.

Claim (Index 5):
The valve assembly of  claim 4 , further comprising:\n a first hole extending through a wall of the guide tube, wherein the first hole fluidically connects the fluid chamber with an interior of the guide tube; a second hole extending through the wall of the guide tube, wherein the second hole is positioned axially between the control seat and the first position of the control piston; and a third hole extending through the wall of the guide tube, wherein the third hole is positioned axially on the guide tube between the piston housing and the outlet of the flow duct, wherein the control piston blocks the first hole from the control opening in a first position, and wherein the second hole and the third hole fluidically connect the fluid chamber with the interior of the guide tube and the outlet of the flow duct when the piston is in the closed position and the control piston is in the first position.
