摘要:
The invention relates to a method for producing a throttle valve unit for installation into a flow conduit through which a gas flow passes. A flap shaft of the throttle valve unit is affixed to a stamped insert part inside a fastening region. The stamped insert part, which includes an insert border, is molded into a housing. At the same time as the stamped insert part is molded into the housing, the flap shaft affixed to the stamped insert part is molded-in inside the fastening region. A planar region of the stamped insert part connected to the flap shaft is cut out from this stamped insert part.

In a flap valve for controlling a gas flow, with a valve tube (11) that carries the gas flow and with a valve flap (14) that is pivotable in the valve tube (11) and that in its closing position rests sealingly with its outer contour on the inner wall of a flexible thin-walled tube (20) disposed coaxially in the valve tube (11), and with a valve shaft (15) connected to the valve flap (14) in a manner fixed against relative rotation, it is provided, in order to attain a sensitive adjustment of the valve flap (14) and for the sake of technologically simple, inexpensive production of the flap valve (14), that the valve shaft (15) is positioned at an acute angle (&ggr;) relative to the valve plane, and the thin-walled tube (20) is formed directly and integrally onto the valve tube (11) (FIG. 2).

A magnet valve for tank venting in motor vehicles, having at least one valve opening forming a sealing seat and having a spring-loaded valve member cooperating with the at least one sealing seat for opening and closing the valve and actuated by an electromagnet counter to the restoring force of a restoring spring. Downstream of the valve member, a flow element that throttles the flow of a gas is disposed, the shape of the flow element is adapted to the opening cross section of the sealing seat that cooperates with the valve member, for determining (metering) the flow quantity of the gas through the cross section of the flow element when the magnet valve is open. The shape of the flow element is determined (metered) in such a way that the area of the opening cross section of the effective valve seat is greater than 2.5 and preferably greater than 9 times the area of the effective cross section of the flow element.

A 2/2-way solenoid valve which is open when it is without current and is inserted into a diesel fuel-carrying line to a high-pressure pump. The solenoid valve functions as an emergency shutoff or when the device is tested by supplying the solenoid valve with power which then closes the line to a high-pressure pump, which interrupts the high-pressure delivery. The solenoid valve has an armature, which functions in an armature chamber that is filled with diesel fuel and is sealed in relation to the outside by two O-rings. A plastic valve housing protects the coil and the contacting of the electrical connections from corrosion and protects the individual wires of the coil from vibration stresses. The solenoid valve is designated for use in common rail injection systems of vehicular internal combustion engines.

An internal combustion engine that has an intake device with a turbocharger compressor device with a valve in a bypass line that bypasses the compressor device. To assure a simple, economical installation of the valve in a way secured against relative rotation, the valve is secured to a tubular receiving element, by means of a bayonet mount, formed by the valve and receiving element. The valve is intended for internal combustion engines that are equipped with a turbocharger compressor device.

A fuel line connector for producing recirculation of leakage fuel in a fuel injection valve in which communication of a fuel line with a connection bore of a housing, and with the holder of a fuel injection valve is produced. This is achieved by providing that the fuel line connector has elastically deformable retaining arms, which, after a connecting stub of the fuel line connector has been plugged into a connection bore, engage the housing that contains the connection bore from behind.
摘要:
A coil former with injection-molded encapsulation has a top fitting in which coil wire guides for guiding a coil wire are formed. By virtue of the specific shape and arrangement of the coil wire guides, it is ensured, in particular together with a special design of the housing which surrounds the coil former, that the coil wire is only stressed in its longitudinal direction. As a result, damage or preliminary damage of the coil wire is prevented and reliability is increased.

A measuring instrument for contactless detection of an angle of rotation comprises a carrier plate (52) consisting of a magnetically soft material that serves as a rotor. The stator of the sensor comprises at least two parts, the ends (18 and 17) of which terminate in two planes. The measuring gap (M1) containing an element (20) that is sensitive to a magnetic field is located between the ends (18, 17). Due to the fact that the ends (17, 18) of the two stator parts (13, 14) terminate in different planes, the measuring element (20) can be situated in a very small measuring gap (M1) in which the magnetic flux of the magnet (5) can be concentrated.
摘要:
A solenoid valve for tank ventilation in motor vehicles, comprising a magnetic yoke with at least one valve opening and with a cooperating spring-loaded valve member for opening and closing the at least one valve opening. The valve element constitutes a magnetic armature of an electromagnet and is disposed between the magnetic yoke of the electromagnet and a hollow, cylindrical magnet core of the electromagnet. A valve seat body which is separate from the magnetic yoke and contains the at least one valve opening is disposed in an axial opening in the magnetic yoke, and on a side remote from the valve member. The valve seat body rests against a housing wall of the solenoid valve by use of a support element made of a damping material.
摘要:
A fuel tank ventilation valve for a Laval nozzle, which has a sensitive regulation of the through flow quantity. The valve has a valve seat which is embodied on a valve seat body which has at least one opening that can be closed by the valve member. A cross section of the at least one opening is embodied as essentially smaller than an entry cross section of the Laval nozzle that is disposed spaced apart from the valve seat. The valve is suited for a metered introduction of fuel that has evaporated from a fuel tank of a mixture-compressing internal combustion engine with externally supplied ignition into an intake tube of the engine.
