摘要

An infinitely variable belt drive having a pair of belt clamping servos (22, 24, 30), (54, 56, 58) and a ratio control servo (28, 32, 34), a high pressure source connected to a common high pressure feed circuit for the clamping servos, a ratio control servo, a low pressure source that is independent of the high pressure source, and a high pressure accumulator and pressure amplifier system that is adapted to supply the clamping servos with a high pressure with minimal high pressure fluid flow.
