    摘要: An automotive brake system comprises a sump fluidly disposed in a housing, constructing a brake unit, and in the middle of a suction circuit of a pressure apply device including at least a pressure apply pump. During vehicle dynamics control or during vehicle stability control, the pressure apply rapidly sucks the brake fluid stored in the sump and quickly performs a pressure apply action, irrespective of the distance between the brake unit and a brake-fluid source. This ensures a smooth brake-fluid supply to the suction circuit of a return pump returning the brake fluid from the wheel-brake cylinder to the brake circuit upstream of a fluid-pressure control valve unit.

    摘要: A brake-fluid reflux type anti-skid brake control system for an automotive vehicle, comprises a main brake-fluid line fluidly disposed between a master cylinder and a wheel cylinder for supplying a brake fluid from the master cylinder to the wheel cylinder during usual braking, a brake-fluid reflux line arranged in parallel with the main line for returning the brake fluid from the wheel cylinder to the master cylinder side during operation of the system, directional control valves arranged for controlling the respective fluid flow in the main brake-fluid line and in the reflux line, depending upon a skidding condition of a vehicle wheel, and a plunger type control valve arranged between the outlet port of the master cylinder and an upstream junction of the main line and the reflux line. The control valve is responsive to a fluid pressure representing whether the anti-skid brake control system is in an operative state or in an inoperative state, in a manner so as to provide a constricted brake-fluid flow therethrough to the wheel cylinder in the operative state of the system and to provide a full brake-fluid flow therethrough to the wheel cylinder in the inoperative state of the system.

    摘要: Revolving rollers, each provided on an outer peripheral surface thereof with revolving roller grooves extending therearound, are caused to mesh with a rack rod thread of a central rack rod with an axial angle over a lead angle of the rack rod thread and arranged for rotation on a holder member to be twisted. The holder member is rotated round the rack rod by a motor to translate the rack rod. A large thrust can be generated while ensuring a high reliability since a high efficiency is achieved by realizing rolling contact in set points of mesh of the rack rod thread and the revolving roller grooves, points of mesh are made planar, and interference in other points than the points of mesh can be suppressed. Also, play can be restricted by assembling the revolving rollers to the rack rod thread while applying torque in a direction, in which the axial angle is increased.
