摘要： A fuel pressure damper (10) includes a housing (14) defining an inlet (40) for receiving fuel from a fuel rail. A cover (12) is coupled to the housing to define an interior space (15). A flexible diaphragm (30) has a periphery (32) secured to at least the housing or the cover and has a freely movable central portion (28) that divides the interior space into first and second isolated chambers (42, 44). The diaphragm has a shaped feature (48) such that the central portion can be displaced over a distance. The inlet communicates with the second chamber (44). A spring cup (26) is in the first chamber (42) and is engaged with the central portion of the diaphragm. A variable rate compression spring (18) is in the first chamber and is disposed between the spring cup and the cover. The central portion of the diaphragm and spring are constructed and arranged to dampen low to high magnitude fuel pressure pulsations in the second chamber.

摘要： A compact fuel pressure regulator (10) includes a housing (12) with an interior (13) communicating and inlet opening (16) and an outlet opening (20). The housing defines a valve seat surface (26) in the interior. A cover (22) is provided at an end of the housing and is disposed in the interior. The cover includes a through-hole (24) therein that communicates the outlet opening with the interior. A valve structure (28) is movable within the interior to control fuel flow between the inlet opening and outlet opening. A spring (30) is engaged between the valve structure and the cover so that when pressure of fuel at the inlet opening is greater than a force of the spring, the fuel pushes the valve structure against the bias of the spring and away from the valve seat surface so that fuel flows around a periphery of the valve structure to the outlet opening.
摘要翻译：紧凑的燃料压力调节器（10）包括具有内部（13）连通和入口开口（16）的壳体（12）和出口开口（20）。壳体在内部限定阀座表面（26）。盖（22）设置在壳体的端部并且设置在内部。该盖包括其中的通孔（24），该通孔将出口开口与内部连通。阀门结构（28）可在内部移动以控制入口开口和出口之间的燃料流动。弹簧（30）接合在阀结构和盖之间，使得当入口开口处的燃料的压力大于弹簧的力时，燃料推动阀结构抵抗弹簧的偏压并远离阀使得燃料在阀结构的周边周围流到出口。

摘要： A fuel pressure damper (10) includes a housing (15) defining an inlet (46) constructed and arranged to receive fuel. An orifice disc (54) is provided at the inlet and includes at least one orifice (58). A cover (22) is coupled to the housing. A flexible diaphragm (12) has a periphery fixedly secured to at least the housing or the cover and has a freely movable central portion (36). A compression spring (14) biases the diaphragm to a normal position. In an operating position, the central portion of the diaphragm alone, or in combination with the spring, is constructed and arranged to dampen fuel pressure pulsations at the inlet. The orifice is constructed and arranged to ensure that pressure pulsations of a certain magnitude are prevented from entering the damper and damaging the diaphragm.
