Abstract
A solenoid valve device and specifically a solenoid operated injection valve wherein the bouncing of the valve element upon closing is dampened. This is done by providing an inertial mass which is slidable relative to the stem portion of the valve element and contacts fixed abutments on the stem portion of the valve element to limit the relative movement in each direction. In addition, a cushioning arrangement is interposed between the inertial mass and the abutment for cushioning the stopping of the inertial mass.
