The VVR technology is an innovative concept derived from the aerospace ‘bootstrap’ reservoir design Its purpose is to replace on selected applications the ‘classic’ atmospheric hydraulic reservoir (tank) The VVR mostly targets industrial, mobile, military, marine and offshore fluid power systems. It can be from open loop systems to hydrostatic drives. In conventional systems, the reservoir oil capacity is sized in relation to the pump flow rate (typically 2-3 times) whereas the VVR solution requires to size from the system oil displacement and thermal expansion. Displacement could be from differential cylinders where the rod volume only must be accounted for . Main return flow goes direct to pump inlet where the VVR connected to the return line will compensate for volume differential and thermal expansion, thus making the VVR totally independent from system flow. The VVR is not part of the cooling equation; hence, classic reservoir offers very poor cooling capacity. It is in our philosophy that the coolers must provide 100% if this task. Why use a bulky heavy mass of fluid to obtain the same result... The VVR is a sealed airless slightly pressurized device that offers many benefits; 1 to 8 PSID /,07 to 0,5 bar - Considerable weight reduction (up to 100 times) - Considerable space reduction - Reduced fluid cost - Environment friendly and mostly suitable for biodegradable fluids - Open loop system becomes a closed loop system - Exposure to solid contaminants and moisture (oxidation) is eliminated - Increased fluid and components life thus lower maintenance cost and increased system reliability - Reduced contamination risk when filling - Reduced oil disposal volume / recycling - Reduced fire hazards and consequences - Reduced decontamination cost if a major leak occurs - Pump positive inlet pressure allows machine to operate in any orientation and altitude - Pump positive inlet pressure reduces pump noise and allows for better performance and increased speed - VVR’s can be installed in series or parallel to increase effective volume - VVR’s can be installed on independent pump to isolate circuits - 3 sizes available: 400 in³ / 6,6 l - 800 in³ / 14 l and 1300 in³ / 21 l displacements with many options available
