Electrical leads for a valve

摘要

A valve for metering a fluid (liquid or gaseous medium), in particular, a fuel injector for internal combustion engines, having a valve housing, an actuator accommodated in the valve housing and acting on a valve member, an electrical connector accessible on the outside of the valve housing, and an electrical supply lead that produces an electrical connection from the connector to the actuator and has two lead strands, each having a flexible strand section. To optimize the electrical supply lead to lower production costs, simplified valve assembly and anti-twist protection for the actuator, each lead strand is made of an electrical conductor provided with a plastic sheathing and having a front and rear, in each case elongated conductor section and a middle conductor section in between that has at least one meander-shaped curvature for realizing the flexible strand section, and a plastic bridge member, in one piece with the plastic sheathings in the area of the middle conductor sections of both electrical conductors, connects the two lead strands to form a torsionally stiff supply-lead module.

1. A valve, which meters a fluid, including a liquid or gaseous medium, comprising:
a valve housing; an actuator accommodated in the valve housing and acting on a valve member; an electrical connector accessible outside of the valve housing; and an electrical supply lead that produces an electrical connection from the electrical connector to the actuator, the electrical supply lead having two lead strands, each having a flexible strand section, wherein each of the lead strands is made of an electrical conductor provided with a plastic sheathing and has a front and rear, in each instance an elongated conductor section and a middle conductor section in between which has at least one meander-shaped curvature that realizes the flexible strand section, and a plastic bridge member, in one piece with the plastic sheathings in an area of the middle conductor sections of both conductors, connects the two lead strands and forms a torsionally stiff supply-lead module, and wherein the actuator is supported via a gimbal mounting on a valve-member side and on a valve-housing side, respectively, and the elongated front conductor sections of the electrical conductors are secured in position in the valve housing, and the elongated rear conductor sections are secured in position in the actuator.
