Fuel-injection valve

Guenter Dantes, +1 more
TLDR
In this article, a high-pressure injection valve for directly injecting fuel into a combustion chamber of a compressed-mixture, spark-ignition internal combustion engine is described, and a slit-type flow outlet is formed between the slit-forming element and a front face of the valve seat body.
Abstract: 
The invention relates to a fuel-injection valve, in particular a high-pressure injection valve for directly injecting fuel into a combustion chamber of a compressed-mixture, spark-ignition internal combustion engine. Said valve is characterised in that an outlet opening (23) is provided downstream of the valve seat (20), the downstream end of said opening having a slit-forming element (30) that to a great extent closes the outlet opening (23). A slit-type flow outlet (35), through which a fuel spray can be discharged in a fan-type jet, is formed between the slit-forming element (30) and a front face (34) of the valve seat body (16).

Fluid injection nozzle

Akinori Harata, +1 more
TL;DR: A fuel injector has a chamber between a valve body and a plate in which a plurality of through holes are formed as mentioned in this paper, and fuel flows along an inner inclined surface of the valve body turns to the through holes and flows into the through hole from all directions and collides with each other at inlets of the throughhole.

Fuel Injection Valve

Tsuchiya Masahiro, +9 more
TL;DR: In this article, the phase angle of force applied to the primary oscillation system by the secondary oscillator is also staggered from that of the force applied by the SOS, which in turn makes it possible to achieve very accurate fuel-injection control.

Biased spring hard needle retractable IV catheter

Edward D. Dysarz
TL;DR: In this article, the biased spring hard needle is held within the soft catheter and the elongated hollow barrel by a latch means, and when the latch means is disengaged with the biased needle, the spring section of the needle that is near the second end of the bias needle instantly withdraws the needle out of the catheter, and the needle is fixed to an end cap at the second-end of the hollow barrel.
