Document Type and Number:
WIPO Patent Application WO/2020/084948
Kind Code:
A1
Abstract:
This power transmission device comprises an accumulator (9B), a control valve unit (7), and a piston pressure-receiving chamber (R1) for a brake (52), connected to the inside of the control valve unit (7) via a connection oil passage (47). The power transmission device is configured such that: the accumulator (9B) is arranged on the outside of the control valve unit (7); and a supply and discharge passage (98) for the accumulator (9B) is connected to the connection oil passage (47) via the piston pressure-receiving chamber (R1). As a result, the control valve unit (7) is more compact and the vicinity of the area where the control valve unit (7) is housed can be more compact.
