An electromagnetically actuable rate control valve for controlling a delivery rate of a high-pressure pump includes an electromagnet, a valve element, an armature shaft, and at least one strength element. The valve element is movable in an axial direction and is configured to open and to close the electromagnetically actuable rate control valve. The armature shaft transmits a force. The force is produced by the electromagnet and acts on the valve element in the axial direction. The at least one strength element is configured to raise at least the strength of the armature shaft. The armature shaft includes a needle region adjacent to the valve element and an armature region remote from the valve element. The needle region and the armature region are integral with each other.

Electromagnetically actuated rate control valve, in particular for controlling the delivery rate of a high-pressure fuel pump

The invention relates to a fuel supply system for an internal combustion engine, having a unit such as a pressure regulator, mounted in electrically insulated fashion and including an electrically conductive housing, and the housing is connected via an electrical connection to a defined electrical potential. As a result, static charging of the unit, which could become dangerous, is precluded. The fuel supply system is intended in particular for pumping fuel to an internal combustion engine of a motor vehicle.

Fuel supply system

The invention relates to a device ( ) for pressure regulation, having a housing ( ) and a closing body ( ) received axially movably therein, wherein the housing ( ) has at least one pressure medium inlet ( ) and one pressure medium outlet ( ), and the closing body ( ) is prestressed by a helical spring ( ) against a valve seat ( ) in the housing, and at least one compensation means for the helical spring ( ) is provided. The invention provides that as the compensation means, a compensation element ( ) disposed between the closing body ( ) and an end, oriented toward the closing body ( ), of the helical spring ( ) is provided, which is braced resiliently in the radial direction on the inner wall of the housing ( ) and, with its central region ( &prime;), is in preferably frictional-engagement contact with the closing body ( ). The central region ( ) of the compensation element ( ) is embodied as dome-shaped, and radially protruding spring arms ( &Prime;) are disposed peripherally to the central region ( ) of the compensation element ( ).

Device for pressure regulation

The invention relates to a pressure regulator for a fuel injection system of an internal combustion engine, in which a pressure difference prevailing between a pressure inlet and a pressure outlet can be kept essentially constant by opening and closing at least one valve, which valve includes a valve closing member forced into the closing position against a valve seat by the action of a valve closing spring. The valve spring is formed by means of at least one pivotably supported valve leaf spring, and an arm, toward the valve seat in terms of the pivotable bearing means, of the valve leaf spring is braced on the valve closing member, and an arm of the valve leaf spring located on the side opposite the valve seat is braced on a support body, in such a way that a torque equilibrium prevails at the valve leaf spring.

Pressure regulator

The invention relates to a flat pipe pressure damper for damping fluid pressure pulsations in fluid lines, in particular fuel pressure pulsations in fuel supply lines of motor vehicles, having at least one chamber, of which at least a part of the chamber wall, in operative connection with the fluid, can be elastically deformed by the fluid pressure pulsations. The invention makes the provision that a part of the chamber is filled with a fluid.

The pressure regulating valve ( ) proposed here can be designed with the aid of the outflow throttle restriction ( ) downstream of the valve seat ( ) in such a way that the pressure regulating valve ( ), as the fluid flow becomes greater, sets or adjusts a smaller pressure difference at the pressure regulating valve ( ), as a result of which the line losses that can never be avoided can be compensated for. The pressure regulating valve is suitable in particular for a fuel supply system of a motor vehicle having an internal combustion engine.

Pressure regulating valve and method for producing a pressure regulating valve

The invention relates to a fuel supply system for an internal combustion engine, having a unit, such as a pressure regulator, mounted in electrically insulated fashion and including an electrically conductive housing, and the housing is connected via an electrical connection to a defined electrical potential. As a result, static charging of the unit, which could become dangerous, is precluded. The fuel supply system is intended in particular for pumping fuel to an internal combustion engine of a motor vehicle.

Fuel supply device

A liquid filter (,) with a built-in pressure regulator (,) for fuel is proposed, wherein the pressure regulator (,) with its diaphragm (,) is built on the housing (,) on a component (,) on the front with at least one connection (,). The disk-shaped diaphragm (,) has a single clamping site (,) on its external circumference and a centrally arranged movable closure closure member (,). The diaphragm (,) is acted upon by pressure in a pressure chamber (,) connected with the clean side against the force of a spring (,) in a gas-filled spring chamber (,). The integration of the pressure regulator (,) in the housing (,) permits a simple, compact, cost-effective construction of the liquid filter (,), through whose valve (,) in the pressure regulator (,) only cleaned fuel flows and which is insensitive to backpressure in the tank connection (,).

Liquid filter with built-in pressure regulator

A liquid filter (,) with a built-in pressure regulator (,) for fuel is proposed, in which the pressure regulator (,) with its diaphragm (,) is mounted on the inside of a cap (,) that has the inflow connector (,) and the tank connector (,). The diaphragm (,), which experiences a flow on its inside, is acted upon by the pressure of the fuel on the clean side (,) of the filter element (,), and the flow through the filter element is radially from the outside inward. Integrating the pressure regulator (,) in the cap enables a simple, compact, economical design of the liquid filter (,), through whose valve (,) in the pressure regulator (,) only cleaned fuel flows.

Liquid filter with integral pressure regulator

A pressure regulating valve has a valve chamber having an inlet for connecting to a pressure source, a discharge chamber communicating through a valve opening with the valve chamber, a valve member, a valve seat surrounding the valve opening, a valve closing spring which presses the valve member against the valve seat with an adjustable spring force, and a throttling surface arranged downstream of the valve opening so that between the valve member and an inner wall of the discharge chamber, a pressure is formed at the valve member which counteracts the spring force.

Pressure regulating valve

This pressure regulator prevents unpleasant vibration of the closing body. In the pressure regulator, a friction spring that is simple to mount is provided, by means of which the vibration of the closing body can be suppressed or reduced. The pressure regulator is intended in particular for fuel supply systems of motor vehicles that have an internal combustion engine.
