摘要： In a droplet ejector equipped with an ejection port for ejecting minute droplets of a liquid, the ejection port 61 or the ejector and a conductor 10 such as a vehicle body are made electrically conductive to increase the electrostatic capacity of the ejection port 61 or the ejector and to suppress enlargement of the potential difference between the ejection port 61 and the liquid caused by flow electrification of the liquid. When the potential difference is large, a coulomb force acts between the electrified droplets and the electrostatically-charged ejection port, causing problems such as delayed or insufficient droplet discharge, but such problems are solved by increasing the electrostatic capacity of the ejection port 61 or the ejector.

摘要： A fuel injector is provided. The fuel injector includes a sleeve having a first end proximate an outlet; a piston slidingly received in the sleeve, the piston having a first end proximate the outlet; a pumping chamber at least partially defined by the sleeve between the first end of the piston and the outlet; and a normally-open inlet valve through which fuel passes to enter the pumping chamber.

摘要： A metal valve body having a fuel injection port includes a nozzle plate accommodation part accommodating a nozzle plate of synthetic resin and aligning a center of the nozzle plate with a central axis of the valve body. A front end surface abutting against the nozzle plate is accommodated in the nozzle plate accommodation part. A swage projection fixes the nozzle plate to the front end side on which the fuel injection port is formed. The nozzle plate is swage-fixed in the state in which a spring action part is elastically deformed on the front end side of the valve body by the swage projection, and a nozzle hole formation part is constantly pushed against the front end surface of the valve body by the elastic force of the spring action part.

摘要： A fuel injector, in particular for a high-pressure injector for direct injection of fuel into a combustion chamber of an internal combustion engine, has compression of a fuel/air mixture with spark ignition. On the downstream end of the valve a valve seat element (26) is provided, to which a perforated disk (70) acting as a flow restrictor is connected downstream. A swirl element (47) is situated upstream from the valve seat (27) which imparts an atomization-promoting rotational motion to the fuel to be injected. In the valve seat element (26) downstream from the valve seat (27) an elongated outlet orifice (32) is provided which opens directly into an orifice (73) in the perforated disk (70) attached to the valve seat element (26). The width of the outlet orifice (32) is greater than the width of the orifice (73), at least at its narrowest location, so that it is possible to adjust the steady-state flow rate of the valve at the orifice (73).
