ACCUMULATING NOZZLE Russian patent published in 2009 - IPC F02M61/10 

FIELD: motor car construction.

SUBSTANCE: invention relates to propulsion engineering, particularly to combustive installation of internal combustion engine with inflammation against compression. Accumulating nozzle of diesel engine consists of nozzle case, fuel of approach channels, under-needle area. In the second cavity in the capacity of spring abut is piezoelectric crystal element. On needle-valve there are implemented two cavities, connecting fuel channels, providing fuel to overflow from one cavity to other at default needle-valve. Fuel is fed into under-needle area at elevated needle-valve. Over-piston areas of the first and the second cavity and also over-needle area allows fuel channels for fuel drainage.

EFFECT: increasing of fuel supplying energy and, as effect, for improvement of fuel spraying, and also for providing of serviceability of accumulating nozzle.
