Embodiment Construction

[0018] This embodiment is a brake valve with non-decompression direct supply capability, which includes a housing 1, a brake decompression valve 2, electric valves 7 and 8 hydraulic switches.

[0019] The brake pressure relief valve 2, the electric valve 7 and the hydraulic switch 8 share a housing 1, which are respectively installed in three inner cavities of the housing 1, and the housing 1 is an assembly frame, It is also an integral part of the brake pressure reducing valve 2, the electric valve 7 and the hydraulic switch 8.

[0020] There are three chambers in the housing 1, which are respectively the brake pressure reducing valve chamber, the electric valve chamber and the hydraulic switch chamber, and the brake pressure relief valve 2, the electric valve 7 and the hydraulic switch 8 are respectively installed in the in each chamber. The chambers communicate with each other through oil passages.

[0021] There are two oil passages communicating with each chamber in the...

Abstract

A brake valve with non-decompression direct supply capability comprises a brake pressure relief valve, an electric valve, a hydraulic switch and a casing. The brake pressure relief valve, electric valve and hydraulic switch are respectively installed in the brake pressure relief valve chamber, electric valve chamber and hydraulic switch chamber in the housing, so that the housing is both an assembly frame and a brake pressure relief valve. , electric valve and hydraulic switch components. The chambers communicate with each other through oil passages. The invention is installed near the pedal mechanism under the bottom plate of the cockpit of the aircraft, and the driver depresses the brake pedal to operate it, outputs the required brake pressure, and realizes normal braking or take-off line braking. The invention conforms to the principle of man-machine engineering, simplifies the braking system, and improves the reliability and safety of the aircraft braking system. In addition, the brake valve with non-decompression direct supply capability of the present invention integrates independent components and accessories, and is manufactured according to a modular design, which is convenient for use and maintenance.

Description

technical field [0001] The invention relates to an aircraft wheel hydraulic brake system, in particular to an aircraft brake valve which normally provides decompressed brake pressure and can directly output the pressure of the supply source when needed. Background technique [0002] The brake valve is the basic component of the aircraft brake system. This brake valve is actually a variable pressure reducer. During normal braking, the driver usually manipulates the brake valve through the pedal mechanism to reduce the high-pressure hydraulic pressure provided by the hydraulic brake system supply source to the required brake pressure, and output it to the wheel brake device for braking. Due to the increase of aircraft take-off thrust, especially the use of carbon brakes, the brake pressure required for take-off line braking has doubled (some have exceeded twice the maximum normal brake pressure), and the brake pressure output by the brake valve of the normal brake system cann...
