Conways in line Anti-Sumping Valve is
designed to fit unobtrusively in the Flexible Oil Feed Pipe A65.
It is automatically opened by the action of the Oil Pump's suction, and is a
safe way of preventing drain down into the Crankcase when the Engine is idle.
Easily fitted and very reliable, it is suitable for Series "A's" and
all Post-War Vincents with Single Start Oil Pumps.
Modestly priced, it is supplied with fitting instructions and Pipe Ferrules.
Here we have a photo of the valve on a Series 'C' Comet, fitted neatly behind
the gearbox.
