摘要： PURPOSE:To aim at a performance improvement, by altering the setting value of braking hydraulic pressure in consecutive order so as to secure a desired slip factor, and adopting such a learning control system as securing the desired slip factor eventually. CONSTITUTION:Each detection signal out of car speed sensors 5-8 is inputted into an electronic control circuit 18 in which a judgement of antiskid control takes place. Solenoid valves 24a, 38a and 38d are selected by each of driving signals 18a-18d whereby a motor 30 is driven and braking hydraulic pressure is supplied. When the solenoid valve 24a is selected, a master cylinder 15 and each of wheel cylinders 9 and 12 are all intercepted, therefore these solenoid valves 38a and 38d are selected and these wheel cylinders 9 and 12 are decompressed. Afterward, hydraulic pressure in a hydraulic pump 31a is taken in, making the braking hydraulic pressure go up. Thus, the braking hydraulic pressure in these wheel cylinders 9 and 12 is controlled for increase or decrease whereby antiskid control is carried out.

摘要： PURPOSE: To simplify a hydraulic pressure circuit by using the function of a valve body both as a proportional valve and a cut valve.
CONSTITUTION: Hydraulic pressure is applied to a input port 15 from a pressure source, and when the value thereof is under given value, a piston is pressed in a (a) direction by means of a spring 10, and therefor the hydraulic pressure in the side of the input port 15 is equal to that in the side of the output port 16. Further, when the hydraulic pressure over given value is applied to the input port, the piston is moved in a (b) direction, and the piston 7 is subtly oscillated to repeat the engagement and the disengagement of the piston with a valve seat 13, and thus the pressure is raised while decompressing the hydraulic pressure in the side of the output port 16 at a constant ratio. In this case, a valve body 1 acts as a proportional valve. On the other hand, when the hydraulic pressure is supplied to a control input port 19, the piston 7 is moved in a (b) direction, the head portion 12 of the piston 7 contacts with the valve seat 13 to close a passage 14, the valve body acts as a cut valve to cut off the communication of the input port 15 and the output port 16.

摘要： PURPOSE:To obviate any accident of a collision against an obstacle, byforbidding a braking device, which keeps a car in a braking state in time of stoppage and is released of the braking state in time of starting, to release the braking state even in time of starting in the case where there is the obstacle. CONSTITUTION:In time of car stoppage, a microcomputer 37 selects a solenoid valve 26 with a signal out of a car speed sensor 36, making a parking brake mechanism 10 operate. When the brake 10 operates with certainty, the microcomputer 37 makes the solenoid valve 26 return to the original state with a signal out of a parking switch 34, but the parking brake 10 is kept up in a braking state as a claw 16b of a lever 16 engages a tooth 15b. In time of starting, either of shift switches 32a and 32b is turned to ON, and when an accelerator switch 31 is turned on as well, the microcomputer 37 selects a solenoid valve 24. Therefore, engagement between the claw 16b and the tooth 15b comes off, thus the baking state is released. When an obstacle exists in a starting direction, the microcomputer 37 will not select the valve 24 even in time of starting with signal out of an obstacle sensor 35. In consequence, the braking stae is maintained.

摘要： PURPOSE:To reduce the loss by guiding the stream from the revolution direction to the axial direction of an impeller at a discharge port. CONSTITUTION:As for the edge surface on the discharge port 6 side of a partitioning part 100 for partitioning a suction port 1 and a discharge port 6, the side 100b far from the side 100a close to the discharge port 6 is formed to bulge out along the opposite direction in the revolution direction of an impeller 3. Accordingly, the fuel stream flowing to the discharge port 6 from a pump flow passage flows along the edge surface on the discharge port 6 side of the partitioning part 100, and as fuel flows closer to the discharge port 6 from the pump flow passage, the fuel is guided in the axial direction from the revolution direction of the impeller 3. Accordingly, fuel flows smoothly in the axial direction from the revolution direction of the impeller 3, and the disturbance of the stream at the discharge port can be reduced.

摘要： PURPOSE:To omit pipelines and make the device lightweight by fitting a gas pump driven by a prime mover to the booster cell of a brake booster and storing at least the pump section of the gas pump in the booster cell. CONSTITUTION:A vacuum pump 16 constituted of a motor section (prime mover) 17 and a pump section 18 driven by this motor section 17 is fixed to the booster cell 11 of a brake booster 10. In this case, the motor section 17 is arranged outside a booster cell 11, on the other hand, the pump section 18 is stored in a constant-pressure chamber 13. The air in a booster constant-pressure chamber 13 is sucked through an intake port (not shown in the figure) by the pumping action of the pump section 18 driven by the motor section 17 and discharged to the atmosphere side through a discharge port 24, thereby the constant-pressure chamber 13 is kept at the predetermined degree of vacuum. According to this constitution, conventional communicating pipelines are not required, thus the number of components is decreased and the weight is reduced.

摘要： PURPOSE:To carry out a stable braking operation by properly controlling the distribution of the braking force of plural brake systems to each wheel of a vehicle in accordance with the change in condition at the time of braking the wheels. CONSTITUTION:A reference pressure form a pilot pipe 156 and a reference pressure from a second pilot pipe 190 are introduced into a variable pressure regulator 210, which is switched over by detecting the differential pressure between pressures flowing in a branch pipe 155 and an input pipe 173. When the hydraulic pressure flowing in the input pipe 173 becomes above alpha times the hydraulic pressure flowing in the branch pipe 155, the variable pressure regulator 210 is shifted to a first position, connecting a pilot pipe 173 to a return pipe 173 via a third port 213 and a second port 212 and, as a result, the pressure in an input chamber 412 is returned to a reservoir 18 via the input pipe 173 and return pipe 172. Thereby, the pressure flowing in the input pipe 173 is always suppressed to alpha times the hydraulic pressure flowing in the first branch pipe 155.

摘要： PURPOSE:To enable the opening or closing of two ports by one solenoid valve, by energizing two valve bodies which open or close two ports in the same direction respectively through respective energizing means, and further providing a moving element to be moved by a solenoid coil between two valve bodies. CONSTITUTION:When a current is not passed through a solenoid coil 26, the first valve body 4 opens the first outlet port 2 by the energizing force of the first coil spring 15, and further the second valve body 5 receiving the energizing force of the first coil spring 15 via a moving element 6 opens the second outlet port 3. On the other hand, when the solenoid coil 26 is magnetized, finally in the state in which the moving element 6 has moved at its maximum, the first valve body 4 is brought in contact with the first flow passage shut-off surface 28 to close the first outlet port 2, and this state is maintained by a magnetic attraction force of the solenoid coil 26. And the second valve body 5 is also maintained in such a state that the second outlet port 3 is closed by the energizing force of the second coil spring 24.

摘要： PURPOSE:To prevent a reverse flow of fluid, by cutting off communication of a suction port with a communication groove from when a vane is contained in a vane chamber to when a slide contact position of a rotor with a cylindrical internal peripheral surface passes through an opening position of the suction port. CONSTITUTION:When a vane 4 retracts into a vane chamber, a delivery port 10 is opened to a position opposed to a flat surface part A between communication grooves 20 of the vane 4. A suction port 9 is prevented from communicating with the delivery port 10 from when the vane 4 is contained in the vane chamber 11 to when a rotor 3 comes to the uppermost position. Accordingly, noise and efficiency are prevented from worsening with no reverse flow of fluid into the suction port.
