LUBRICATING DEVICE

摘要

A small-sized lubricating device. In the lubricating device (1-1), the degree of opening of a flow rate adjusting valve (13) mechanically increases as clutch engaging pressure increases, and the flow rate of oil sucked from an oil pan (12) into a sucking section (11b) of a jet pump (11) increases as the clutch engaging pressure increases. As a result, with an increase in the clutch engaging pressure, the flow rate of the oil discharged from a discharge section (11d) of the jet pump (11) increases. This means that the flow rate of oil lubricating a lubricating section (20a) of a friction clutch (20) increases as the clutch engaging pressure increases. Accordingly, the flow rate adjusting valve (13) alone can change the flow rate of oil discharged from the jet pump (11) without the use of a torque/oil flow rate conversion mechanism such as a torque sensor. This allows the device to be downsized.
