System for preventing cavitation in hydrostatic gearing - has hydrostatic circuit with drive pump with variable displacement

摘要

The hydraostatic gear has a closed circuit and a drive pump with variable displacement, wherby a motor is connected by a first hydraulic lead and a second hydraulic lead to the drive pump. A pressure accumulator is attached by a first non-return valve to the second hydraulic lead by the second non-return valve. ADVANTAGE - The pressure accumulator is attached to the hydraulic circuit so that cavitation is avoided and increased fluid flows in the circuit.
