Abstract
An injection device comprises a housing comprising an inlet and an outlet and an outlet sleeve mounted within the housing and comprising at least one radial flow port therethrough for permitting fluid communication between the inlet and the outlet. A flow sleeve is mounted over the outlet sleeve and is arranged to move between a first position in which the at least one radial flow port is at least partially closed and a second position in which the at least one radial flow port is opened. The injection device also includes a flow sleeve actuator operable by a biasing arrangement and inlet pressure at the inlet of the housing to permit the flow sleeve to be selectively moved between its first and second positions to vary flow through the at least one radial flow port between the inlet and the outlet.
