A regulator circuit provides a constant direct current to a load, for example, a string of batteries. The current is regulated to be independent of the load and supply voltage variations and can be operated under open or short circuited load conditions for an indefinite time without damage. The generator includes a pair of SCRs in a full wave current supply which provide phase angle controlled current through the load and a sensing resistor in series therewith. The voltage drop across the resist...

A regulating valve, comprising a housing having a cylindrical valve chamber, is disclosed. The valve chamber is provided with at least one inflow and at least two outflow ports. The inflow and the outflow ports can be at least partly closed off as required by a single common valve body arranged in the valve chamber that can rotate about an axis. The valve body acts as a rotary valve and can be actuated by a drive. The inflow and/or at least one of the outflow ports is surrounded on the side of t...

A regulating valve comprising a housing having a cylindrical valve chamber, the valve chamber being provided with at least one inlet and at least two outlets, the inlet and the outlets being at least partially closeable as needed by a common valve body arranged in the valve chamber and rotatable around an axis, the valve body being operable by an actuator, the inlet and/or at least one of the outlets being surrounded by a sealing device on the side of the housing facing the valve body and the se...

The proposed device is intended for use in motor vehicles and permits a high level of accuracy in measurement and simple and cost-effective manufacture. It comprises a shaft component (12) arranged adjustably in a housing element (21) and a rotating unit (20') of a rotation angle sensor (2) which can move in relation to the fixed unit (20). The stator element (21) consists of two rounded cusp-shaped subcomponents held with a bracing unit and secured in a stator mount (23). There is a clearance r...

A regulating valve for a heat-transferring medium has a valve member controllable primarily by an electrical actuating member, but in the event of failure of the electrical actuating member, a thermostatic actuating member, operating independently of the electrical actuating member and of electric power, is provided in order to prevent damage to the system by driving the valve member when a predetermined temperature is exceeded.

A control system for coupling two final control elements as regards the actuated position and the actuating force, in which each final control element is assigned a separate force-control loop, these loops being coupled to one another by way of the actual-force values prevailing at the final control elements, is to be improved as regards its versatility for different applications. According to the invention, this is achieved by virtue of the fact that the two force-control loops are coupled by a...

A regulating device for rotary adjustment of a regulating member comprises a regulatable electrical control drive connected to the regulating member and a restoring device which acts on the regulating member or on the control drive and which returns the regulating member to a starting position in which, for example, the emergency operation of an internal combustion engine is ensured optimum operation of the regulating member without constant reference to the emergency situation, a release device...

For a closed-loop feedback control of a controlled system having a predetermined set course and a control trajectory for use in controlled systems in motor vehicles, an output trajectory of the controlled system is measured for the entire control time in which the control trajectory is applied to the controlled system, an error of the controlled system is detected as a function of predetermined set course and the output trajectory, and a new control trajectory is calculated for each instant of a...

A regulating system comprises an input terminal for applying an input voltage, and an output terminal for providing an output voltage. A semiconductor element is connected between the input terminal and the output terminal and is operable to regulate the output voltage. A regulating signal generation circuit generates the regulating signal and comprises a current mirror arrangement including a first and second current mirror path, wherein a controlled current source is connected in series to the...
