SEAL FOR USE IN DEVICE FOR SUPPLYING FUEL GAS TO INTERNAL COMBUSTION ENGINE, INTERNAL COMBUSTION ENGINE AND METHOD FOR SUPPLYING FUEL GAS TO INTERNAL COMBUSTION ENGINE Russian patent published in 2023 - IPC F02M21/02 F02B19/00 F02M55/00 F16L41/02 F16L41/08 F16L47/32 

FIELD: internal combustion engines.

SUBSTANCE: fuel gas (G) is supplied through a tube (30) into the prechamber (21) of the internal combustion engine (1). The prechamber (21) is made inside the chamber housing (20), which is inserted into the cavity (10) of the engine housing (2), and the tube (30) is inserted into the channel (16) of the engine housing (2), which communicates with the cavity (10). The seal (40), which may be made of an elastomer, includes a wall (41) defining an internal space (42) that is accessed through the wall (41) through first, second and third openings (50, 60, 70). The first section (43) of the wall (41), forming the first and second openings (50, 60), is formed in the cavity (10) such that the chamber housing (20) can be inserted through the openings (50, 60) into the internal space (42) of the seal, while the second portion (44) of the wall (41), containing the third opening (70), is inserted into the channel (16) such that the tube (30) can be inserted into the interior space (42) of the seal through the third opening (70). The tube (30) is in sealed fluid communication with the prechamber (21) through the inlet (23) in the chamber housing (20) by means of sealing areas (51, 61, 71).

EFFECT: invention makes it possible to simplify the installation and maintenance of a device for supplying fuel gas to an internal combustion engine and to ensure tightness when fuel gas flows through the device for supplying fuel gas.
