A pre-chamber fuel admission valve (44) includes a fuel inlet (50), a fuel outlet (76), an actuated valve, and a check valve (74). The fuel inlet (50) receives a supply of a fuel. The fuel outlet (76) delivers the fuel to a pre-chamber (42). The actuated valve is between and in fluid communication with the fuel inlet (50) and the fuel outlet (76). The actuated valve controls a flow of the fuel from the fuel inlet (50) to the fuel outlet (76). The check valve (74) is biased in a closed position and between and in fluid communication with the actuated valve and the fuel outlet (76). The check valve (74) is configured to open and allow the fuel to exit the fuel outlet (76) in response to a fuel pressure exceeding a pre-chamber (42) pressure plus a bias pressure, and the check valve (74) is configured to close in response to the pre-chamber (42) pressure plus the bias pressure exceeding the fuel pressure. |
