Abstract: An injection valve is provided. A first conduit is disposed between first and second chambers of the valve. An entrance to the first conduit is located within the first chamber. A second conduit is concentrically disposed within the first conduit so that there is a first flow passage between the first and second conduits connecting the first and second chambers. The second conduit has an entrance communicating with the first chamber via the entrance of the first conduit and an exit defining a first outlet port of the valve. A cover opens and closes a first inlet port of the first chamber, and a biasing device biases the cover closed. An actuator moves the cover from the closed position to open the first inlet port.
