    • Die Erfindung betrifft eine Radbremse zum Abbremsen von vorzugsweise nicht angetriebenen Rädern bei Land-, Luft- und Raumfahrzeugen. Die Radbremse besteht aus einem Flüssigkeitskreislauf, bei dem durch das umlaufende Rad 4 eine Verdrängungspumpe 2 betrieben wird, die eine Flüssigkeit, vorzugsweise destilliertes Wasser, über ein Drosselventil 10 in einen Vorratsbehälter 8 und aus diesem dann zurück zur Pumpe fördert. Über das Drosselventil 10, das vorzugsweise von einer Anti-Blockier-Einrichtung gesteuert wird, ist der Bremsdruck einstellbar. Der Vorratsbehälter 8 ist mit einem Überdruckventil 12 versehen, das bei verschieden einstellbaren Drücken, bei Wasser vorzugsweise bei 25 bar, öffnet.

    • An anti-skid hydraulic braking system for a vehicle having the usual wheel cylinders, master cylinder and brake pedal, with a brake release valve interposed ahead of each wheel cylinder for selectively reducing the pressure in the wheel cylinder in accordance with a slip signal generated at the associated wheel upon going into a relatively slipping condition of incipient skid. Each brake release valve has an inlet port connected to the master cylinder, an outlet port connected to the wheel cylinder, and a control port. In the preferred embodiment the valve has a first or "signal" piston movable in response to slip signal pressure applied to the control port and a second piston for creating a cavity for temporary accommodation of brake fluid from the wheel cylinder. When the pressure at the control port rises, signaling an incipient skid, movement of the signal piston first cuts off the inlet port to isolate the wheel cylinder from the rest of the regular braking system and then shifts the second piston to create a cavity for accommodating slight reverse flow of fluid from the wheel cylinder, thus relieving the brake pressure sufficiently to avoid a skid. The inlet-outlet ports are bridged by a check valve to insure immediate release of the wheel cylinder upon release of the brake pedal. In an alternate form of the invention utilizing an electrical slip signal, the signal piston is replaced by a solenoid plunger.

    • In an hydraulically-operated braking system for vehicles a supply of hydraulic fluid under pressure from a pump is utilized for applying a wheel brake, and the pump is responsive to rotation of the braked wheel so that the brake applying force is dependent upon the speed of rotation of the wheel and the wheel is automatically prevented from locking, and the system incorporates an hydraulic accumulator adapted to define a reservoir of high pressure for providing an instantaneous supply of high pressure fluid to apply the brake.This invention relates to improvements in hydraulically-operated braking systems for vehicles of the kind in which at least one brake is adapted to be applied in response to a supply of hydraulic fluid under pressure from a pump, and the pump is responsive to rotation of a wheel so that a brake applying force is dependent upon the speed of rotation of the wheel and the wheel is automatically prevented from locking.In known braking systems of the kind set forth a time delay may occur whilst the pump is generating within the system sufficient pressure to apply the brakes. Such a delay may be considerable in systems for operating large brakes where it is inconvenient to utilise a large pump adapted to operate at a high delivery rate when the speed of the vehicle is high.According to our invention an hydraulically operated braking system of the kind set forth incorporates an hydaulic accumulator adapted to define a reservoir of high pressure for providing an instantaneous supply of high pressure fluid to apply the brake.The hydraulic accumulator is connected to the brakes through a brake control valve of which the operation is controlled by the pressure from the pump thereby ensuring that operation of the brake is dependent upon the speed of rotation of the wheel.Preferably, by-pass means are provided for by-passing the brake control valve so that the pressure from the pump can be applied directly to the brake in the event of exhaustion of pressure in, or failure of, the hydraulic accumulator.The accumulator is charged between brake applications by the pressure from the pump which is supplied to the accumulator through a pressure regulating valve so constructed and arranged that when the brake is applied communication between the pump and the accumulator is cut-off, and the pump pressure is solely applied to the brake control valve.

    • A brake control system includes a pressure operated wheel brake, a master cylinder, a positive displacement pump drivingly connected to the wheel, a brake actuator providing a brake pressure to the wheel brake in proportion to the pump generated pressure, an orifice exhausting the pump generated pressure at a rate which prevents the pump generated pressure from operating the actuator throughout the range of vehicle speeds, and a slip control valve in series connection with the orifice and providing a variable restriction to exhaustion of the pump generated pressure in proportion to the difference between the master cylinder and wheel brake pressures. The flow area presented by the variable restriction of the slip control valve decreases at a decreasing rate as the differential between master and wheel brake pressures increases.
