Title: Rolf Lasaar: Innovator in Hydrostatic Technology
Introduction
Rolf Lasaar is a notable inventor based in Grossostheim, Germany. He has made significant contributions to the field of hydrostatic technology, holding two patents that showcase his innovative spirit and technical expertise.
Latest Patents
Lasaar's latest patents include a hydrostatic variable displacement pump and a hydrostatic power unit. The hydrostatic variable displacement pump features a displacement volume that can be set by an electro-hydraulic control device, which includes a safety function to ensure reliability. In fault scenarios, the pump can be set to a neutral position, enhancing its safety. The electro-hydraulic control device utilizes a single setpoint encoder to specify the displacement volume, while an electrically actuated valve device controls the direction of displacement.
The hydrostatic power unit comprises a variable displacement machine that operates both as a pump and a motor. It is designed to work in conjunction with an internal combustion engine, providing hydraulic fluid from a tank when functioning as a pump. When acting as a motor, it serves as a hydraulic starter for the engine. The displacement volume is controlled by a positioning piston device, which is supplied with hydraulic fluid from a charging pressure circuit. This innovative design allows for efficient operation and enhanced performance.
