Latest Patents

One of Helmut Hirn's key patents is for a temperature compensated piezoelectric actuator arrangement. This electronically controlled actuator arrangement features a temperature-compensated piezoelectric transducer, which includes at least one stack of piezoelectric oxide discs. The design incorporates a mechanical throw-transmitting lever system arranged in series with the transducer. This lever system consists of one or more levers integrated into a plane-parallel plate. When the actuator arrangement is in a rest position, the force introduction points lie flush with one plane face of the plate, while the force deployment points lie flush with the opposite face. This innovative actuator arrangement ensures that the lever system is minimally affected by temperature variations, making it particularly suitable for rapid-action hydraulic valves. Helmut Hirn holds 1 patent for this invention.
