摘要： PURPOSE:To prevent a bearing from deteriorating early owing to outflow of grease filled up in the bearing by dissolving a pressure difference between respective chambers through forming a connecting holes along the fitting surface of a rotor for mutually connecting plural chambers which are divided by the bearing in the rotor. CONSTITUTION:When a main shaft 8 is rotated by the drive shaft (9a) of a motor 9, a rotor 13 is revolved in sliding contact with the inner periphery surface (4a) of the casing 4, together with an eccentric shaft 10 being rotated eccentrically. As the result, a vane 15 is reciprocated in a vane chamber 14 therefore, the volumes of the suction chamber and the delivery chamber are expanded and contracted to get pumping action. While, the inside of the rotor 13 is divided into two chambers A, B and the pump of this type has a defect that the two chambers A, B produce pressure difference putting a ball bearing 12 between them and the grease filled into the ball bearing 12 flows out thoroughly. To cope with this, a boss 25 is formed on the inner surface of the rotor 13 and plural connecting holes 26 both ends of which are open to the two chambers A, B are formed in the boss 25.

摘要： PURPOSE:To improve the control accuracy while maintaining the normal brake feeling by constructing such that the brake condition of each wheel is detected and the constant hydraulic pressure in a hydraulic circuit led to a pressure regulator is fed, interrupted or released through first and second switching valves. CONSTITUTION:Pressure modulators 310-312 coupled with the hydraulic brake pressure conduit of a master cylinder 102 and the constant hydraulic pressure conduit of a hydraulic pump 107 are arranged while also coupling with the wheel cylinders 150-153 of respective wheels. The operation is now explained with reference to the right side of a front wheel. A first switching valve 630 for feeding/interrupting the constant hydraulic pressure of the hydraulic pump 107 and a second switching valve 631 for releasing said constant hydraulic pressure are arranged in a conduit coupled with a pressure regulator 801 and the pressure modulator 310. Consequently, the pressure of the pressure modulator 310 can be increased/decreased by controlling the first and second switching valves 630, 631 in accordance with the braking condition based on the information from various sensors, thereby the brake force from the wheel cylinder 150 can be made suitable for the brake condition.

摘要： PURPOSE:To keep off any pushing-up phenomenon of a brake pedal so as to cause pressure oil out of a pressure source not to be reached to the side of a master cylinder, by closing a first select valve at the time of antiskid control thereby intercepting the interconnection between the master cylinder and a wheel cylinder. CONSTITUTION:Both feed pipes 20 and 30 are connected to a pressure chamber of a master cylinder 3, while this feed pipe 20 is connected to a brake pipe 21 to be interconnected to a wheel cylinder 5 for a left front wheel and a brake pipe 22 to be interconnected to a wheel cylinder 6 for right rear wheel via a first select valve 101. And, this first select valve 101 is of 3-port-two position valve and interconnects the feed pipe 20 to each of branch pipes 21 and 22 at a first position, while it intercepts the feed pipe 20 from each of these branch pipes 21 and 22 at a second position. An electronic control unit selects first select valves 101 and 102 from the first position to the second position when it judges that antiskid control is started, thus brake oil inside the wheel cylinder is released to a reservoir 11 by way of an oil pipe 50.

摘要： PURPOSE: To prevent an inner turning wheel whose load has been decreased from showing the tendency to lock at early stages by controlling first and second pressure regulating devices at least before antiskid control has been initiated, so that the brake pressure of the inner turning wheel become smaller than that of the outer turning wheel. CONSTITUTION: This vehicular brake control device includes first and second pressure regulating devices installed in right and left wheel brake systems to independently regulate brake forces to each wheel, a turning state detection means, and an antiskid control means. At least before the brake pressure of the right or left wheel whose tendency to lock becomes excessive is reduced, each pressure regulating device is controlled according to a turning state signal from the turning state detection means so that of the right and left wheels being braked, the inner turning wheel has a smaller brake pressure than the outer turning wheel. When the turning state signal indicates the shift of a great load, each pressure regulating device is controlled so that the difference in brake pressure between the inner and outer turning wheels increases.
