Title: Karlheinz Widmann: Innovator in Hydraulic Control Systems
Introduction
Karlheinz Widmann is a notable inventor based in Lohr, Germany. He has made significant contributions to the field of hydraulic control systems, holding 2 patents that showcase his innovative approach to engineering challenges.
Latest Patents
Widmann's latest patents include a control arrangement for hydraulic consumers and a proportional magnet. The control arrangement addresses the issue of inadequate power from delivery pumps by reducing the flow rate set at directional control valves in equal proportions. This is achieved by supplying electrical signals proportional to the flow rates to a summation stage, where the sum voltage is compared to a limit value corresponding to the maximum pump delivery flow. When this limit is exceeded, a control signal is generated to jointly reduce the stroke of all driven directional control valves. The proportional magnet features a housing with a movable armature bar influenced by an armature winding, complemented by a hydraulic unit for operation.
