* Features

As the former piston pump and motor have the complex structure and are very big in size, and has high unit cost of production, low efficiency and in case of the vane pump is always compressing the cylinder wall by sharp edge of vanes, it has the defect that the friction resistance is too high, and the abrasion is excessive, and especially the reverse rotation is impossible. But this roll-vane pump/motor, is very little friction part, service life is ten times longer than existing products, and has 96% of efficiency, and as the reverse rotation is just same as forward rotation, and very small in size, it almost can not be compared with the existing products.
Roll-Vane pump/motors most vantage point is that combines use as hydraulic pump and hydraulic motor without any modify, if you driving the shaft then working as pump, and if you supply pressured liquid in any direction then working as hydraulic motor in same efficiency
