HYDRAULICALLY OPERATED TRANSMISSION

A hydraulically operated transmission (1) comprises: a pressure regulating device (pressure regulating solenoid valve 41) that regulates the pressure of a hydraulic fluid to a hydraulic pressure engagement chamber (21) of a friction engagement element (second brake (BR2)) for starting a vehicle; and a lubrication control valve (61) that is disposed in a lubricating oil supply circuit (33) to supply lubricating oil to the friction engagement element. When the friction engagement element is engaged while starting the vehicle, the lubrication control valve (61) operates so that the flow rate of the lubricating oil supplied to the friction engagement element when the regulating pressure due to the pressure regulating device is set to be a first prescribed pressure, which is a complete engagement state, or higher and is lower than a second prescribed pressure set to a value less than the high pressure is greater than when the regulating pressure is equal to the second prescribed pressure orgreater. 液压工作式变速器(1)包括调压
