Definitions
- the invention relates to an electromagnetic valve train according to the preamble of claim 1.
- an armature which is directly or indirectly coupled to a gas outlet valve, is usually moved back and forth by the action of coils.
- a power supply which provides the required energy, is necessary for loading the coils.
- the coils themselves are controlled by a power unit, which in turn is controlled by a control and regulation device.
- a sensor is often also arranged in the actuator, from whose signal the armature or valve position can be determined indirectly or directly.
- the control and regulation part as well as the power electronics or other elements of the electromagnetic valve train are combined and designed to be integral with one another.
- the aim of the present invention is to avoid these problems in the electromagnetic valve train.
- At least one information connection is established between two devices of an electromagnetic valve train by means of a glass fiber connection.
- a fiber optic connection is not susceptible to EMC problems.
- fiber optic cables do not have to be electrically insulated. Otherwise existing contact difficulties have to be solved by appropriate connectors.
- connections between a valve or actuator sensor on the one hand and the control and regulating device on the other hand, between an engine control and the control and regulating device, or between the power electronics and the control and regulating device by means of fiber optic connections It is essential in this context that the connection only serves as information transfer.
- An energy supply line on the other hand, is not replaced by a fiber optic cable.
- the various connections can also be made partially with glass fiber connections. For example, a section of the route that poses particular EMC problems can be secured using a glass connection.
- FIG. 1 shows a block diagram of a first embodiment of the present connection
- FIG. 2 shows a block diagram of a second embodiment of the present connection
- Figure 3 is a block diagram of a third embodiment of the present connection.
- a power supply 10 and a motor controller 18 are provided.
- a valve control is specified which is connected on the one hand to the power supply 10 and also to an actuator 14. These connections are carried out in a conventional manner by means of electrical cables.
- the connection between a sensor 16 coupled to the actuator 14 and the valve control 12 is made by means of glass fibers.
- the connection between the valve control 12 and the engine control 18 is also carried out by means of an optical fiber connection.
- the devices of the electromagnetic valve train 20, namely the actuator 26, the power electronics 24, the control and regulation electronics 22 and the sensor 28, are combined in an integral unit.
- the corresponding connections among themselves are provided in the integral unit itself. For this reason, in this embodiment it is only necessary to provide an electrical cable connection to the power supply 10 and an optical fiber connection between the control and regulating electronics 22 and the motor control 18.
- the devices power electronics 24 ' , actuator 26' and sensor 28 ' are shown combined.
- the power supply 10 is connected to the power electronics 24 'in the usual way with an electrical cable.
- the power electronics 24 'and the control and regulating electronics 22' as well as the sensor 28 'and the control and regulating electronics 22 ' as well as the control and regulating electronics 22 'and the motor control 18 are coupled via fiber optic connections.
- the present combination of information connection between individual elements of the electromagnetic valve train and conventional power connections by means of electrical cables, which is realized via fiber optic connections, ensures an interference-free exchange of information between the individual parts as possible and thus arouses the functional reliability of the entire electromagnetic valve train arrangement.
