Latest Patents

One of Pastleitner's latest patents is a method for controlling a coolant pump of an internal combustion engine. This invention involves an electrically driven coolant pump with an electromotor-pump unit. The electronic control unit generates a pulse-width modulated control signal for the pump based on engine operating parameters. To ensure timely recognition of irregularities and malfunctions, the control unit is connected to an error detector that identifies abnormal control signals and pump operating conditions. Additionally, it features a speed controlling device for the pump speed, along with an emergency device for the coolant pump.

Another significant patent is for an electrically operated coolant pump. This invention includes a rotor encompassed by a stator of the electromotor, featuring a rotor shaft designed with a hollow structure for liquid supply to the impeller. The stator is arranged in a stator chamber of the motor housing, with the rotor shaft rotationally held in the housing. To enhance efficiency and reduce wear on the bearings, at least one roller bearing is designed as a leakproof roller bearing, integrating sealing elements in the roller bearing cages. The stator chamber is also designed to be leakproof from the conveying liquid.
