VALVE-CONTROLLED PISTON MACHINE AND METHOD FOR OPERATING A VALVE-CONTROLLED PISTON MACHINE

摘要

The invention relates to a valve-controlled piston machine - especially a radial piston machine DVR - comprising a plurality of piston-cylinder units and a low pressure connection and a first high pressure connection. Each piston-cylinder unit has a low pressure valve connected to the low pressure connection and a first high pressure valve connected to the first high pressure connection. The piston machine is provided with another high pressure connection, each piston-cylinder unit having another high pressure valve connected thereto. The low pressure valve and the high pressure valves are actively controlled.
