The damping device includes a damper element which has at least one damper diaphragm fastened in a damper housing and is arranged to define a fuel chamber which communicates via a feed pipe with a fuel distributor line. The feed pipe is oriented toward a flow tube which communicates with a fuel supply line and protrudes into the fuel distributor line. The fuel chamber of the damper element communicates via a further feed pipe with the fuel distributor line. The feed pipe and the flow tube are axially spaced apart from one another by a distance (A).

摘要： A damper element is proposed which serves to damp a pulsating fluid flow, and in particular to smooth out and reduce pressure fluctuations arising in fuel supply systems for internal combustion engines in motor vehicles. The damper element includes at least one damper diaphragm which is fastened in a damper housing and defines a fluid chamber on one side. A connection fitting is disposed on the damper housing and is inserted into a plug connection of a fluid flow cross section. A flow opening is embodied in the fluid flow cross section, being open toward the fluid chamber and toward the fluid flow cross section. The flow opening and the fluid flow cross section are penetrated by a flow tube arranged to protrude therethrough, and into which a first fluid line, which discharges into the fluid chamber, is embodied. Between the flow tube and the wall of the flow opening, an annular, second fluid line is embodied.

摘要： A pressure control valve to control the pressure of a fluid in a fluid system so that it remains constant. This type of valve can be utilized as element of a fuel injection system for internal combustion engines, and has storage means which are independent of the valve member, and actuatable by the pressure of the fluid. The pressure control valve comprises a housing and a support assembly urged toward a valve seat by a control spring. Additionally, a storage spring in the support assembly urges a closing member toward the valve seat. The closing member is slidably received in a bore in the support assembly. The support assembly is connected to a membrane which is tensioned between the housing members. Other variations of this device are also revealed herein.

摘要： A damper element is proposed which serves to damp a pulsating fluid flow, in particular to smooth out and reduce pressure fluctuations arising in fuel supply systems for internal combustion engines in motor vehicles. The damper element includes a base and a cap, which are welded to one another and a damper diaphragm is clamped between these elements. The damper diaphragm, in order to prevent diffusion of the fluid into a damper chamber of the cap, is embodied either as a polyimide diaphragm or as a combination of a fabric diaphragm and a polyimide diaphragm. The clamping area of the cap is embodied as inclined slightly toward the damper diaphragm by an angle .alpha., so that a long-term fastening and sealing of the damper diaphragm is assured.

摘要： A pressure regulator device which enables greater coaxiality tolerances in the individual parts, without impairing the ability to assemble the parts or impairing a necessary tight sealing. The pressure regulator valve is disposed in a guide opening of a fuel distributor line and a receiving opening of an outlet connection. The pressure regulator valve has a bottom part and an outlet neck. An annular neck groove is embodied on the outlet neck and an annular housing groove is embodied on the bottom part. A sealing ring is disposed in each groove. The annular neck groove is defined by an outer shoulder and an inner shoulder, which has a smaller diameter than the outer shoulder. In the same way, the annular housing groove is defined by an outer shoulder and an inner shoulder, which has a smaller diameter than the outer shoulder. The outer shoulders of each groove allow centering of the pressure regulator valve while the inner shoulders allow concentricity errors. The pressure control device is applicable to fuel injection systems for internal combustion engines.

摘要： A fuel injection system for an internal combustion engine is controlled by a follower control loop. The fuel quantity is arbitrarily set by the gas pedal and a first potentiometric transducer generates an electrical command signal. The air flow through the induction tube constitutes the controlled variable whose magnitude is transformed into an electrical signal by a second potentiometer coupled to an air flow rate meter. The two signals are compared at the input of a control amplifier which drives a servomotor. The servomotor adjusts the opening of the air throttle valve of the engine, thereby changing the air flow through the induction tube until the air flow rate meter signals that the air quantity is proportional to the metered out fuel quantity.
