摘要： A hydraulic braking pressure control apparatus provided with a modulator for controlling the supply of control hydraulic pressure to a wheel brake of the vehicle, wherein a partition is provided between a first cylinder portion and a second cylinder portion which are formed in a casing, a first piston adapted to divide the first cylinder portion into an input hydraulic chamber on the partition side and a control chamber on the opposite side is secured to one end of a piston rod extending through the partition slidably and oil-tightly, and a second piston adapted to define an output hydraulic chamber on the partition side within the second cylinder portion is mounted on the other end of the piston rod for axial relative movement. The partition is provided with a valve mechanism capable of disconnecting communication between the input and output hydraulic chambers. The second piston is biased in a direction toward the partition, and by relative movement of the second piston with respect to the piston rod, the interior of the output hydraulic chamber is prevented from reaching an excessive negative pressure level during an anti-lock operation. The apparatus can function as a proportioning reducing valve by forming the first piston with a smaller diameter than the second piston.

摘要： A brake pressure regulator for an hydraulic vehicle braking system. A first inlet chamber (14) and an outlet chamber (20) for a first brake circuit (HzI-RzI) are defined by piston surfaces of different sizes of a stepped piston (30) which controls a valve (40) disposed in a connection between these two chambers (14, 20). The pressure in a second inlet chamber (24) adapted to be connected to a second brake circuit (HzII-RzII) acts on an annular control piston (50) which is acted upon in opposite direction by a spring (60). The control piston (50) surrounds the stepped piston (30) without contacting the same and is sealed radially inwardly against a plug (16) which is inserted in the housing (10) and which in turn surrounds the stepped piston (30) in sealing fashion. When as switching pressure in both brake circuits (HzI-RzI, HzII-RzII) is surpassed, the stepped piston (30), aided by the control piston (50), adopts a position at which the valve (40) closes. Subsequently, the stepped piston ( 30) sealed by only two sealings (32 and 38) reciprocates, against little frictional resistance, between positions in which alternatingly it opens and closes the valve (40), thereby causing a pressure rise in rear wheel brake cylinders (RzI) in circuit at a reduced ratio in comparison with the pressure rise in front wheel brake cylinders (RzII).

摘要： A control valve assembly for vehicle hydraulic brake systems having dual or split hydraulic pressure lines, including a body having two coaxial hydraulic chambers, one chamber being in one pressure line, and the other chamber in the other pressure line. A piston in each chamber is axially and serially arranged with the other piston, the pistons abutting each other at one end. Movement of each piston opens and closes a valve in the respective chamber which opens and closes the respective hydraulic pressure line. Hydraulic pressure acts on a circumferential step on each piston tending to close the valves. A single spring acts on the other end of one piston biasing both pistons in one direction tending to open the valves.

摘要： A control valve for use in an automotive brake system for controlling the brake fluid pressure in rear-wheel cylinders of the type include an inlet chamber communicated with a master cylinder, an outlet chamber in communication with the rear-wheel cylinders, a valve chamber in hydraulic communication with both of the inlet and outlet chambers, the latter being communicated through a valve port, a ball valve floatingly disposed within the valve chamber and actuable to close the valve port when the deceleration of an automotive vehicle reaches a predetermined level, and a differential piston with its free ends disposed in the inlet and outlet chambers, respectively, to be exerted with the brake fluid pressure therein. A variable restriction is disposed upstream or downstream of the valve chamber and is actuable in response to the flow rate of brake fluid flowing therethrough in such a manner that when the flow rate exceeds a predetermined value, the flow of brake fluid may be restricted, thereby eliminating the departure of braking force distribution from an idealized distribution when brakes are abruptly applied.
