Abstract: A valve is provided having a circuit that includes an electrical conductor with a temperature-dependent electrical resistance. The electrical conductor is connected in series to an electrical series resistor, which includes a parallel circuit of a non-reactive wire and an NTC resistor. The electrical conductor includes a coil wire wound into a magnetic coil that is operable to move an armature to open or close the valve. The effect of the operation of the valve itself on the magnetic force of the coil is minimized by arranging the NTC resistor to be thermally coupled with the coil wire.

Abstract: An arrangement is provided for use with an internal combustion engine. The arrangement includes an intake tract for the internal combustion engine and a valve that is fluidly connected to the intake tract. An activated carbon filter is located upstream from the intake tract and the valve. The valve is connected to the carbon filter by an intake line. When the valve is open, fluid can flow from the activated carbon filter into the intake tract. A pressure sensor measures upstream pressure (p1) in the intake line. A pump helps generate the pressure (p1) in the intake line. The valve is connected to the intake tract so they cooperate together to form a cavity that is connected to the intake line such that when the valve is closed, the pressure in the cavity is the pressure (p1).

Abstract: A valve is provided having first and second flow channels connected by a passage. A sealing device is operable to open and close the passage to control fluid flow between the first and second flow channels. The sealing device includes a first sealing body and a second sealing body through which the passages extends. The first and second sealing bodies are biased together by a spring to close the passage. The first sealing body is passively movable by fluid and actively movable by an electromagnetic device to open the passage to permit fluid to flow between the first and second passages.

Abstract: A check valve with a a housing having an inlet connected to an outlet. A stop and a membrane are disposed in the housing. The membrane is movable and bendable to control fluid flow between the inlet and the outlet. The stop may be an elongated extension about which the membrane may bend along a line or a curve such that the extension lies between overlapping sections of the membrane.

Abstract: The present disclosure is directed to a circuit for use in actuators, electromotive drives and valves. The circuit includes an electric conductor having a temperature-dependent resistance. The electric conductor includes a coil having a copper wire wound over a coil support. The electric conductor is connected in series with an electrical series resistor, which includes a non-reactive resistor connected in parallel with an NTC resistor. The non-reactive resistor is a wire that is composed of an alloy of copper, nickel and manganese. The wire is wound over the coil. The wire may be wound on an area of the coil support separate from the copper wire. The construction of the circuit minimizes the affect of temperature on the operation of the circuit.

Abstract: A valve is provided having a circuit that includes an electrical conductor with a temperature-dependent electrical resistance. The electrical conductor is connected in series to an electrical series resistor, which includes a parallel circuit of an ohmic resistor and an NTC resistor. The electrical conductor includes a coil wire wound into a magnetic coil that is operable to move an armature to open or close the valve. The effect of the operation of the valve itself on the magnetic force of the coil is minimized by arranging the NTC resistor to be thermally coupled with the coil wire.
