Abstract
A delivery valve for use in a fuel injection system of an internal combustion engine comprises a valve body defining a bore in which is slidably mounted a valve member which is biased towards one end of the bore by a coiled compression spring. A first circumferential groove in the bore communicates with the one end of the bore and a second groove on the valve member communicates with the first groove and is exposed beyond the other end of the bore when the valve is opened to allow fuel flow past the valve. The valve member is moved by fuel pressure at the one of the bore and the extent of movement of the valve member against the action of the spring is limited.
