摘要： Provided are barrier coatings and methods for applying barrier coatings to piezoelectric actuators that are intended for use in automotive fuel injectors. The barrier coatings are characterised by the presence of at least one organic layer, and additionally metal and/or non-metallic inorganic layers. The barrier coatings described show advantage in resisting permeation by liquid fuel, water and other contaminants.

摘要： A method for enshrouding an actuator for use in a fuel injector, comprising the steps of providing an actuator having a body section, a first end piece and a second end piece; providing a shroud having first and second ends; applying a sealant material to at least one portion of an exterior surface of the end pieces, and/or to at least one part of the shroud; and enshrouding the actuator with the shroud, such that the sealant material provides an intermediate layer between the end pieces and the shroud and forms a fluid-tight seal between them.

摘要： The injection valve has a control valve with a control chamber in which a closing member is disposed. The closing member is pressed against a corresponding sealing seat by a pressure (e.g. fuel pressure) in the control chamber. The closing member merges into a rod that passes through a drain hole and is connected to a spring plate. The spring plate is preloaded against the housing by a compression spring in such a way that the closing member is pressed against an associated sealing seat. The closing member can be raised from the sealing seat by an actuator piston which rests against the spring plate.
