Abstract
An electromagnetic valve assembly is shown having an armature and armature-actuated valve member the mass of which is substantially less than the armature and which is not fixedly connected to the armature; upon electrical energization the armature first overcomes a restraining force and then travels a major part of its stroke before actuating the valve member, at a relatively high speed thereby causing movement of the valve member by kinetic energy of the armature.
