The valve member (250) has: a first pressure receiving area (A₁) to be fed with the feedback pressure of the second oil passage (201e) in a direction to provide the communication between the output port (255) and the drain port (257); a second pressure receiving area (A₂) to be fed with the signal pressure (P SLU ) in a direction to provide the communication the output port (255) and the drain port (257); and a third pressure receiving area (A₃) having an area different from that of the second pressure receiving area (A₂). The signal pressure generating means (SLU;...) feeds the signal pressure to the third pressure receiving area (A₃) at all times and the signal pressure (P SLU ) selectively to the second pressure receiving area (A₂).

    摘要： A hydraulic pressure which is regulated by a pressure control valve (linear solenoid valve) is applied to a hydraulic servo of a brake which is actuated when an engine-brake is actuated. When the engine-brake is actuated, a regulated hydraulic pressure which is applied through a modulator valve controlled by the linear solenoid valve is applied to the brake hydraulic servo. At this moment, the pressure control valve provides high hydraulic pres­sure when vehicle speed is high based on signals from a speed sensor, while, provides low hydraulic pressure when vehicle speed is low based on signals from the speed sensor, so that an engine-­brake force is adequately controlled in accordance with vehicle speed. Furthermore, in the case that signals from a foot brake sensor is added, the hydraulic pressure in accordance with vehicle speed is set to be low when the engine-brake is actuated. Based on a front wheel rotation sensor and a rear wheel rotation sensor, the control unit calculates rotational difference, thus the engine-brake force is controlled to be low when the rotational difference is large.

    摘要： An oil pressure controller of an automatic transmission which is capable of supplying engaging pressures to hydraulic servos of two frictional engaging elements which require different engaging pressures by a single pressure governing valve with a good pressure governing accuracy. The oil pressure controller comprises a hydraulic power source 10, hydraulic servos 70 and 80, signal pressure generating means 20, a pressure governing valve 30 for governing an oil pressure (P s ) from the hydraulic power source 10 by a signal pressure (P ACC ) and a control valve 40. The pressure governing valve 30 has a pressure receiving face A₁ to which the signal pressure is applied, a pressure receiving face A₂ to which the engaging pressure (P s ) is fed back in the opposite direction and a pressure receiving face A₃ for selecting whether the feedback of the engaging pressure is present or not in order to change the control gain of the pressure governing valve 30 in response to the change of the control valve 40 for selecting the hydraulic servo 70 or 80 to which the oil pressure is supplied.
