Abstract
To provide a short connection hydraulic path structure with a sufficiently large diameter to adequately lower the pressure in a high-pressure hydraulic path while the clutch is off, in a static hydraulic continuously variable transmission for sliding a clutch valve installed within the transmission shaft, to change the power being transmitted and shorten the high-pressure hydraulic path and low-pressure hydraulic path. A high-pressure fluid path is provided for sending hydraulic fluid from the hydraulic pump side to the hydraulic motor side with a low-pressure fluid path for sending hydraulic fluid from the hydraulic motor side to the hydraulic pump side. A hydraulic circuit includes a switching valve for switching the plungers to the high-pressure path or the low-pressure path as a dual structure within a valve body between the hydraulic pump made from multiple plungers, and a hydraulic motor made from multiple motors.
