In distinction, handful of hydrostatic transmission devices accomplish over about sixty five % efficiency. This is because of a mix of inside losses from the pump and motor(s), and losses within the piping and valves.
In an epicyclic CVT (also known as a planetary CVT), the gear ratio is shifted by tilting the axes of spherical rollers to deliver diverse Get in touch with radii, which consequently push enter and output discs. This is analogous in basic principle to toroidal CVTs. Manufacturing variations contain the NuVinci CVT.[28]
