    摘要: In a lubricating device, as a clutch engagement pressure increases, the degree of opening of a flow rate adjusting valve is mechanically increased. Thus, as the clutch engagement pressure increases, the flow rate of an oil sucked from an oil pan to a suction portion of a jet pump is increased. Therefore, as the clutch engagement pressure increases, the flow rate of the oil ejected from an ejection portion of the jet pump is increased. That is, as the clutch engagement pressure increases, the flow rate of the oil for lubricating a lubrication portion of a friction clutch is increased. Accordingly, even if a torque/oil flow rate conversion mechanism, for example, a torque sensor is not used, the flow rate of the oil ejected from the jet pump can be changed only by a flow rate adjusting valve.

    摘要: To provide a lubricating device which can be made compact. In a lubricating device 1-1, as a clutch engagement pressure increases, the degree of opening of a flow rate adjusting valve 13 is mechanically increased. Thus, as the clutch engagement pressure increases, the flow rate of an oil sucked from an oil pan 12 to a suction portion 11b of a jet pump 11 is increased. Therefore, as the clutch engagement pressure increases, the flow rate of the oil ejected from an ejection portion 11d of the jet pump 11 is increased. That is, as the clutch engagement pressure increases, the flow rate of the oil for lubricating a lubrication portion 20a of a friction clutch 20 is increased. Accordingly, even if a torque/oil flow rate conversion mechanism, for example, a torque sensor is not used, the flow rate of the oil ejected from the jet pump 11 can be changed only by a flow rate adjusting valve 13. With the configuration, the device can be made compact.

    摘要: A hydraulic control system comprises: a regulator valve, which regulates a fluid pressure established by an oil pump to an operating pressure required in a control circuit; a signal pressure establishing valve, which applies a signal pressure to the regulator valve to determine a level of the fluid pressure to be established by the regulator valve; and an accumulator, which accumulates the operating pressure to be applied to the control circuit. The hydraulic control system is characterized by: an accumulator control valve, which is arranged between the accumulator and the control circuit, and which is adapted to connect the accumulator with the control circuit when opened, and to disconnect the accumulator from the control circuit when closed; and a signal pressure feeding passage, which delivers the signal pressure established by the signal pressure establishing valve to a signal pressure port of the accumulator control valve thereby actuating the accumulator control valve in accordance with the signal pressure.

    摘要: A hydraulic circuit and a hydraulic control system for preventing fluid leakage and power loss resulting from jamming of contaminants. A first circuit section has an accumulator for storing hydraulic pressure, and a control valve for controlling a passage for delivering fluid from the accumulator to an actuator. Fluid discharged from an oil pump is delivered continuously to a second circuit section. A first filter is disposed on a passage for delivering the fluid from the oil pump to the accumulator for the purpose of removing contaminants finer than those in the fluid to be delivered to the second circuit section from the fluid to be delivered to the accumulator.
