DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] Refer to Figures 1-4, A multi-channel combined valve housing is used to meet the functional requirements of integrating multiple functions of a combined valve, thereby reducing the volume and mass of the combined valve system.

[0023] The combined valve applying this valve body ensures that the combined valve product has the working requirements of multiple passages, can meet the requirements of supplying pressure to the rotor brake and the wheel brake, control the on-off of the rotor brake oil circuit, control the dynamic brake, static brake, and release brake of the rotor, and also has the function of applying pressure on the pressure signaler in real time and feeding back the brake position signal in real time.

[0024] Further, to achieve the connection of each part, the third connection channel 11 is provided to extend from the bottom of the pressure supply interface 4 near the front side of the main body 1, pass through the oil return channel 3, and then extend to the position opposite to the oil return port 5.

A fifth connection channel 13 is provided to extend vertically downward from the top of the main body 1, intersect the third connection channel 11 vertically, and extend and connect to the oil fluid input channel 2. A sixth connection channel 14 is provided to horizontally extend from the front end of the rear side of the main body 1 and connect to the lower side of the pressure supply interface 4 near the rear side of the main body 1. A seventh connection channel 15 is provided to vertically extend into the rear side of the main body 1 in the rearward direction. An eighth connection channel 16 is provided to vertically cross the seventh connection channel 15 from the upper side of the main body 1 and then connect to the oil fluid input channel 2. A ninth connection channel 17 is provided to vertically extend into the main body 1 from the front end of the main body 1, and after vertically intersecting and connecting to the sixth connection channel 14, it connects to the seventh connection channel 15. The pressure supply interface 4 near the rear side of the main body 1 has a tenth connection channel 18 that vertically extends from the bottom to the oil return channel 3 and passes through the oil return channel 3.

A thirteenth connection channel 21 is provided to vertically extend into the main body 1 from the left side of the main body 1 and connect to the twelfth connection channel 20. A fourteenth connection channel 22 is provided to vertically extend into the main body 1 from the front side of the main body 1 to be above the thirteenth connection channel 21 and connect to the lower side of the pressure supply interface 4 near the front side of the main body 1. The outer ends of the fifth connection channel 13, the sixth connection channel 14, the seventh connection channel 15, the eighth connection channel 16, the ninth connection channel 17, the eleventh connection channel 19, the twelfth connection channel 20, the thirteenth connection channel 21, and the fourteenth connection channel 22 are blocked.

[0025] Specifically, the outer ends of the fifth connection channel, the sixth connection channel, the seventh connection channel, the eighth connection channel, the ninth connection channel, the eleventh connection channel, the twelfth connection channel, the thirteenth connection channel, and the fourteenth connection channel are blocked by providing plugs.

[0026] Further, a fifteenth connection channel 25 is vertically provided from the outer end of the convex part 6 to intersect the upper side of the bottom end of the pressure signal setting port 7 and then connect to the oil fluid input channel 2, and the outer end of the fifteenth connection channel 25 is blocked.

[0027] To facilitate the installation and fixation of the valve body (main body 1), a plurality of lower mounting ears 24 are provided on the lower side of the main body 1, and a plurality of upper mounting ears 23 are provided on the upper side. The main body 1 is made of aluminum alloy.

[0028] When the combined valve works, when pressure needs to be supplied to the wheel brakes, pressure is input from the pressure supply port 8 and can directly flow into the wheel brake system (oil fluid input channel 2) through the second connection channel 10 to provide and store hydraulic energy for the wheel brakes. When real-time feedback of the brake hydraulic system signal is required, the pressure input from the pressure supply port 8 will flow into the oil circuit (pressure signal setting port 7) connected to the pressure signal device through the seventh connection channel 15. At this time, the hydraulic pressure of the oil fluid input channel 2 will be real-time feedback to the driver's console; when pressure needs to be supplied to the rotor brake system, the pressure input from the pressure supply port 8 of the housing enters through the valve of the oil fluid input channel 2 and, through the operation of the rotor brake valve, supplies pressure to the rotor brake (entering the corresponding pressure supply interface 4). At this time, the oil return port 5 in the pipeline is closed. If it is necessary to release the rotor brake, operate the rotor brake valve to retract, and the pressure of the rotor brake system flows into the oil return port for pressure relief. Thus, the functions of the entire combined valve are realized. Due to the design of the multi-channel housing, the difficulties in pipeline design and layout are reduced, achieving the maximum utilization of the aircraft space.

[0029] The channels of the above structure achieve the functional connection requirements structurally, meet the use and design conditions, and can be conveniently and simply completed by drilling in terms of technology, enabling different channels to avoid each other in layout and having a compact structure. Therefore, the design of this multi-channel combined valve housing is reasonable, the structure is compact, and the processing is convenient, greatly realizing volume reduction and weight reduction.

[0030] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
