摘要： The invention relates to a fuel-injection system (1) for an internal combustion engine, comprising: at least one injector (3) for injecting fuel into a combustion chamber of a motor, said injector having a high-pressure connection (10), via which it receives a supply of fuel at high pressure, a control valve (64) for controlling the injections of the injector and a low-pressure connection (12) for discharging a controlled quantity of fuel that is accumulated during the control of the injection; and a leakage line (11), which is connected to a fuel-return line (17) by the interposition of a pressure-holding valve (15), which opens in the direction of the fuel-return line when a predefined pressure is exceeded. Said system is characterised in that it is equipped with a throttle device (20) in the vicinity of the pressure-holding valve (15), said device being configured and located in such a way that when the pressure-holding valve is open, a reflection of pressure waves emanating from the injector in the form of negative-pressure waves is damped. Negative-pressure waves emanating from the pressure-holding valve towards the leakage line of the injector are damped or prevented. This reduces the risk of damage caused by cavitation.

摘要： Prior art devices contain diaphragm valves having a high degree of control precision. These diaphragm valves have a first chamber and a second chamber that is separated from the first chamber by means of a valve body. The valve body interacts with a valve seat, and a first connection channel placed in the area of the valve seat leads into the first chamber. A drawback exists due to the fact that these diaphragm valves, in their unaltered form, cannot be used as a pressure release valve. In the inventive device, the pressure control valve is thus improved whereby enabling it to also be used as a pressure release valve. To this end, the invention provides that the valve body (29) has a through channel (48) that, when the pressure control valve (22) is closed, connects the first connection channel (23) to the second chamber (32) of the pressure control valve (22).

摘要： A motorcycle is provided in which a downstream end of an air intake pipe attached with a fuel injection valve is connected to an upper sidewall of a cylinder head of an engine, a fuel supply-side line and a pressure regulator are connected to a fuel supply pipe connected to the fuel injection valve, and a fuel return-side line is connected to the pressure regulator. A front end portion of the fuel supply pipe (78) arranged to be extended to a fore-and-aft direction below the body frame is connected to a fuel injection valve (76), and a return-side connection pipe portion (91) for connecting a fuel return-side line thereto in a same direction as an extended direction of a fuel supply-side line connected to a rear end portion of the fuel supply pipe (78) is provided in a pressure regulator (84) arranged below the fuel supply pipe (76) and connected to an intermediate portion of the fuel supply pipe (78). Thus, it is possible to easily secure a space for arranging the pressure regulator by avoiding interference with the body frame while avoiding an increase of the body width.

摘要： The invention describes a sealing arrangement for a pressure regulator chamber (8) that is connected in an upper part with a low pressure line (14) and in a lower part with a high pressure line (13). For sealing up the high and the low pressure line, a metal sealing element (6,7,23,3) is arranged within the chamber (8) and retained by retaining means (19). For sealing the high pressure line (13) that discharges into a bottom of the chamber (8) a first metallic washer (19) is arranged between a sealing face that surrounds the orifice of the high pressure line and the bottom of the sealing element. The sealing above the low pressure part of the chamber is attained by a washer that (23) is press-fit between the surface of the body (12) in which the chamber (8) is arranged and a further sealing face that is arranged at an upper end of the sealing element. The sealing faces are arranged perpendicularly to a longitudinal axis of the chamber and the sealing element.

摘要： A flow-through pressure regulator (10) includes a retainer (302) that secures a diaphragm (300) relative to a seat (304), and includes an intermediate portion (320), an end portion (322) and a base portion (332). The intermediate portion (320) extends along a longitudinal axis and is fixed with respect to the seat. The end portion extends from the intermediate portion and includes a concave surface facing the seat. The regulator includes multiple flow diffusers such that the end portion includes at least one aperture (326) having a flow axis that is oblique to the longitudinal axis so as to reduce noise due to fluid flow and/or the seat forms a passage having an increasing cross-sectional area from an inlet to an outlet

摘要： A fuel pressure regulator (10) for use with an internal combustion engine includes a housing (12) a valve assembly in the housing, an elastic diaphragm (34) connecting the valve assembly to the housing, a stop (58) on one of the housing (12) or the valve assembly and a spring (22) between the housing (12) and the valve assembly. The housing includes an inlet (14), an outlet (16) and a longitudinal axis. The valve assembly is displaceable along the longitudinal axis by an opening distance when a fuel pressure at least equal an overpressure amount acts on the diaphragm so that the diaphragm does not exceed its yield strength. The diaphragm (34) is in fluid communication with the inlet (14) and elastically displaceable along the longitudinal axis up to a maximum distance. The stop (58) is spaced from the other of the housing (12) or the valve assembly along the longitudinal axis by a travelling distance (D t ) when the valve assembly closes the fluid communication between the inlet and the outlet. The travelling distance is at most equal to the maximum distance and substantially greater than the opening distance.
