摘要： A torque converter having a lockup mechanism makes it possible to positively and forcibly suppress the frictional heat and others generated on the frictional surfaces of the lockup clutch and its counterpart while the lockup clutch is in operation, particularly in a slipping state. Hence, the life of the lockup clutch or that of the torque converter as a whole is prolonged. In this torque converter having the lockup mechanism, a hydraulic control mechanism is provided for maintaining the difference of pressure substantially at a constant level and changing the flow rate of a fluid to be supplied to the frictional surface of the lockup clutch in order to control the slipping state of the lockup clutch. Oil grooves are cut on the frictional member of the lockup clutch.

摘要： In a starting clutch, an oil path for operating the clutch is provided independently of an oil path for cooling a frictional surface. That is, there is provided an oil path exclusively for cooling the frictional surface. Accordingly, a necessary amount of oil can be supplied to the frictional surface, which can thus be cooled efficiently.

摘要： In addition to a first oil pump directly connected to an engine, a second oil pump is provided which is driven by an electric motor. Accordingly, a start clutch engaging pressure is applied through first and second solenoid-operated valves. The electric motor-driven pump is of the constant pressure type, and therefore its start, at the start of the automobile, can be achieved with a simple control program. After the start of the automobile, the solenoid-operated valve is switched over to the other one, so that the oil pressure is applied from the first oil pump directly connected to the engine, whereby the battery power consumption is minimized. This oil circuit is applied to various kinds of friction engagement clutches.

摘要： A tube-pressed brake has a tube, which is inflatable by injection of a pressure fluid thereinto such that a torque can be transmitted to a counterpart. The tube-pressed brake comprises a pressure fluid circuit for circulating the pressure fluid through an interior of the tube. The tube may be provided with a pressure fluid supply hole and a pressure fluid discharge hole, and the pressure fluid circuit may be provided with a first pressure control device arranged upstream the pressure fluid supply hole and also with a second pressure control valve arranged downstream the pressure fluid discharge hole. The pressure fluid circuit may comprise a main circuit and a pressure control circuit. Through the main circuit, the pressure fluid is allowed to successively flow through a reservoir, a pump, the first pressure control device, the tube, the second pressure control device and the reservoir in this order. The pressure control circuit allows the pressure fluid to flow from a point of the main circuit, the point being located between the pump and the first pressure control device, to the reservoir via a relief valve.
