Abstract
An injection valve which serves to inject fuel into the intake manifold of a vehicle engine. The valve has a spin chamber upstream of the injection port which can be connected with a return line to the supply pump providing the pressure, for the purpose of continuous maintenance of a spinning motion of the fuel. The closing body of the valve has a projection extending into the injection port and beyond the valve seat which prevents drip formation when the valve opens.
