VAPOUR FUEL INJECTION VALVE

摘要

A vapour gas injector valve (1) for the injection of liquid petroleum gas (LPG) and other gaseous fuels into the cylinder (2) of an internal combustion engine includes a valve chamber (21) having an inlet port and an outlet port having a flared throat. A valve member is trapped within the valve chamber and moveable between a first position in which it seals against a valve seat surrounding the outlet port, and a second position in which gas may flow from the inlet port to the outlet port. The valve member comprises a disc of hard magnetisable material having one or more holes through it. An electrical winding is selectively energisable to create a magnetic field within the valve chamber to draw the valve member from the first position to the second position.
