PRESSURE STABILIZER, GAS ENGINE SYSTEM AND GAS PRESSURE CONTROL METHOD Russian patent published in 2021 - IPC F02D19/02 F02M21/02 

FIELD: mechanical engineering.

SUBSTANCE: invention can be used in engines running on natural gas. The pressure stabilizer (100) contains a housing (10) that has a gas inlet chamber (11) and a piston chamber (12). A gasket (13) is provided between the gas inlet chamber (11) and the piston chamber (12). The gasket (13) is provided with a through hole. The piston (20) is located in the piston chamber (12) with the possibility of sliding movement and is provided with a through hole (21) of the piston passing through the piston (20). The spring (30) is located in the piston chamber (12) between the piston (20) and the gasket (13). The end cap (40) is located at the open end of the piston chamber (12) and is provided with a gas outlet (41). The electromagnetic coil (50) is located at the end of the end cap (40) with an outlet (41) for the gas, which is located next to the piston (20). The electromagnetic coil (50) in the excited state generates a magnetic field force to attract the piston (20) so that the piston (20) approaches the end cap (40) with the gas outlet (41). The end cap (40) with the gas outlet (41) is connected to the open end of the piston chamber (12) by means of a thread. The gas engine system and the gas pressure control method are disclosed. EFFECT: decreased gas pressure at the outlet of the pressure stabilizer when the piston moves in the direction of the outlet of the pressure stabilizer.
