Improvement in Pump Efficiency
We have succeeded in improving the efficiency by reducing volume of leakage inside the pump.
In the modification of this time, PC-EPC valve for R pump has been employed. On this valve, the pump shoe's lubricating oil hole diameter as well as the high-pressure oil supply hole for supporting the shoe plate has been made smaller.
(Responding to the independent control of F and R pumps, an EPC valve for PC control has been added.)

Model number of the pump is HPV95+95, the same as Model 7.
