Kraftstoffsystem mit einem Durchflussdruckregler

摘要

A fuel system (1000) for an internal combustion engine (1070) powered by fuel (1012). The fuel system (1000) includes a fuel tank (1010) adapted to contain the fuel (1012), a pump (1020) adapted to withdraw the fuel (1012) from the tank (1010) and to pressurize the fuel (1012), a pressure regulator (1040), and piping connecting the fuel tank (1010) and pump (1020), the piping adapted to supply fuel to the internal combustion engine (1070). The pressure regulator (1040) includes a perforated diaphragm-to-seat retainer (302) and provides at least one of generally constant flow-related noise at all fuel flow rates and generally uniform pressure at all fuel flow rates.
