A flow control valve assembly is connected to the cylinder head of a gas engine for providing an intermittent flow of gaseous fuel in timed relationship to the combustion chamber thereof. A valve cage is removably affixed to the cylinder head, and removably receives a valve cartridge in a telescoping manner therewithin. The valve cartridge cooperates with the valve cage in a manner whereby gaseous fuel flows into the cage, through ports formed in the cartridge, and from the interior of the cartridge into the combustion chamber of the gas engine. The valve cartridge includes a main outer housing which is easily separable into two members. A special seal assembly is received in captured relationship between a valve stem and the two separable members. The unique arrangement of the various components of the cartridge enables the device to be overhauled in a simple and straight forward manner.
