"The abolishment of pain in surgery is a chimera. It is absurd to go on seeking it...knife and pain are two words in surgery that must forever be associated in the consciousness of the patient."
Dr. Alfred Velpeau, French surgeon ; 1839

Optionally, minute amounts of air are bled into the vacuum chamber as the liquid fuel droplets are injected resulting in substantially complete and immediate vaporization of the fuel which is fed as gaseous fuel from the vacuum pump to the intake manifold of an internal combustion engine. A water jacket surrounds the pump for circulating heated liquid coolant from the engine in heat exchange relationship with the fuel in the vacuum pump.Other References
