摘要:
A flow-through pressure regulator (10) includes a retainer (302) that secures a diaphragm (300) relative to a seat (304), and includes a cylindrical portion (320), an axial end portion (322) and an annular portion (332). The cylindrical portion (320) extends about a longitudinal axis (A) and is fixed with respect to the seat (304). The axial end portion (322) extends from the cylindrical portion (322) and extends generally orthogonal relative to the longitudinal axis (A). The axial end portion (322) includes a plurality of apertures (324,326) that permit fluid communication and are selected so as to reduce noise due to fluid flow.
摘要:
A pressure regulator (100) includes a housing (12,14), a divider including a first valve member (36), and a second valve member(64). The housing (12,14) includes an inlet (24) and an outlet (24), and defines an interior volume (52,54). The divider separates the interior volume into first (52) and second chambers (54), and includes the first valve member (36), a diaphragm (40), and a retainer (34). The diaphragm (40) extends between the housing (12,14) and the first valve member (36). Fluid communication between the first (52) and second chambers (54) through the diaphragm (40) is prevented. The retainer (34) secures the diaphragm (40) relative to the first valve member (36), and the retainer (34) is press-fitted with respect to the first valve member (36). The second valve member (64) is arranged between first and second configurations relative to the first valve member (36). The first configuration substantially prevents fluid communication between the inlet (24) and the outlet (18), and the second configuration permits fluid communication between the inlet (24) and the outlet (18).
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.
