GAS INJECTOR Russian patent published in 2008 - IPC F02M21/00 F02M51/06 F16K31/02 

FIELD: mechanics.

SUBSTANCE: proposed injector comprises casing with inlet and outlet channels. Aforesaid casing accommodates solenoid, movable armature rigidly linked up with shut-off member and valve seat. There is a gap between the armature and solenoid core exceeding the shut-off member travel. Aforesaid solenoid represents an armored electromagnetic valve incorporating a special cylindrical pole. Between solenoid core and armature provided is a non-ferromagnetic flexible plate representing a ring with radial cuts arranged on the ring inner side to make teeth bent towards the said armature. Perforated diaphragm is arranged between aforesaid armature and shut-off member and linked up with them. Diaphragm radial rigidity exceeds it axial rigidity. Diaphragm angular rigidity around its lengthwise axis exceeds that around radial axes.

EFFECT: higher wear resistance, faster operation, stable operating properties.
