Abstract: A static hydraulic pressure type continuously variable transmission having a hydraulic closed circuit formed between a swashplate type hydraulic pump and a swashplate type hydraulic motor, in which a high pressure oil passage is communicated through exhaust valves with a number of cylinder bores annularly disposed in a pump cylinder of the hydraulic pump, a low pressure oil passage is communicated through intake valves with the cylinder bores, and a number of distribution valves capable of being reciprocated are radially disposed so as to provide an alternate communication between a number of cylinder bores annularly disposed in a motor cylinder of the hydraulic motor and the high and low pressure oil passages. An eccentric ring for imparting reciprocation to each distribution valve is provided and a discharge side of a replenishing pump is communicated with an inner end surface of each distribution valve to hydraulically urge the distribution valve in a direction of engagement with the eccentric ring.
