A combined delivery and damping valve unit for a fuel system of a compression ignition engine comprises a body having a bore including a wider portion and a narrower portion. A spring abutment for the spring biasing the delivery valve member serves as a seating for a damping valve member. The abutment is retained against the step defined between the wider and narrower portions of the bore by locking members having a wedge section and biased by a spring.
