[0002] Hydraulic boosters are hydraulic devices in aircraft control systems used to assist pilots in manipulating control surfaces. Early aircraft used direct mechanical control. As aircraft size and speed increased, hydraulic boosters were introduced at the end of World War II. They amplify the pilot's control force through parallel hydraulic actuators. This device belongs to the hydraulic position servo mechanism and consists of an input feedback mechanism, a hydraulic distribution mechanism, and an actuator.

A first two-position three-way solenoid valve 201 is installed between the two first pressure reducing valves 202. The input end of the hydraulic booster body 10 is connected to the first two-position three-way solenoid valve 201. Through the upper rotary valve supply unit 2 and the lower rotary valve supply unit 3, it is convenient to meet the dual-path delivery operation of hydraulic oil, thereby expanding the pressure range of the hydraulic oil. The oil heating module 9 consists of a secondary pump station 901 and a heating oil tank 902. The heating oil tank 902 is connected to the output end of the main pump station 1 through the secondary pump station 901. The heating oil tank 902 is equipped with an electric heating wire inside. The output end of the heating oil tank 902 is connected to two oil injection pipes respectively, so that the secondary pump station 901 draws the hydraulic oil in the main pump station 1 into the heating oil tank 902 for heating, which is convenient for meeting the high temperature oil leakage test of the hydraulic booster body 10.

[0020] Please see Figure 1 Automatic input control units 502 are installed between the upper rotary valve oil supply unit 2 and the lower rotary valve oil supply unit 3 and the main pump station 1. The two first pressure reducing valves 202 and the automatic input control units 502 are fixedly installed on the two oil injection pipes. The input end of the hydraulic booster body 10 is equipped with a manual input control unit 501. The manual input control unit 501 and the automatic input control unit 502 form an input control module. The automatic input control unit 502 includes a servo cylinder 5021. The servo cylinder 5021 is fixedly connected to the oil injection pipe. A servo valve 5022 is fixedly installed at one end of the servo cylinder 5021. A second pressure reducing valve 5023 is fixedly installed on one side of the servo cylinder 5021.

[0021] Please see Figures 1 to 4The manual input control unit 501 includes a control mounting housing 5011. A control handle 5013 is rotatably connected to the inner rear end of the control mounting housing 5011 via a pin.

Thus, the push rod 5014 can manually open and close the input end of the hydraulic booster body 10.

The return oil pressure regulating module 4 includes a first throttle valve 401, an overflow valve 402, and a second throttle valve 403. A return oil pipe is provided between the output end of the hydraulic booster body 10 and the main pump station 1.

The input end and the output end of the hydraulic booster body 10 are connected through the first throttle valve 401. The overflow valve 402 is used to overflow the maximum pressure of the return oil pipe, and the flow rate of the return pipe is adjusted through the first throttle valve 401 and the second throttle valve 403.

[0023] Please see Figure 1 A leakage detection module 8 is installed on one side of the return oil pressure regulating module 4. The leakage detection module 8 includes a ball valve 801, a second two-position three-way solenoid valve 802, and a flow meter 803. The ball valve 801 and the second two-position three-way solenoid valve 802 are connected in parallel and are both connected to the return oil pipe located between the first throttle valve 401 and the overflow valve 402. The second two-position three-way solenoid valve 802 is connected to the flow meter 803. The ball valve 801 can extract and measure the returned hydraulic oil, or the second two-position three-way solenoid valve 802 and the flow meter 803 can monitor the flow rate of the returned hydraulic oil. By comparing the input and output hydraulic oil flow rates of the hydraulic booster body 10, leakage tests of the hydraulic booster body 10 at normal and high temperatures can be performed.

[0024] Please see Figure 1 , Figure 5 and Figure 6 On the other side of the return oil pressure regulating module 4, an output pressure module 6 is installed. A spring pressure module 7 is installed at one end of the output pressure module 6. The output pressure module 6 includes two load control boxes 601. A return oil pipe connecting sleeve 602 is fixedly installed on the upper part between the two load control boxes 601. An oil guide seat 607 is fixedly installed in the middle of the two load control boxes 601. A sealing disc 606 is installed at both ends of the oil guide seat 607. A transmission rod 604 is fixedly installed on the inner side of the two sealing discs 606. A conical sealing block 605 is installed on the side of the sealing disc 606 away from the oil guide seat 607. The load control box 601 has an oil drain port 603 at the end away from the oil guide seat 607. One end of the transmission rod 604 passes through one of the conical sealing blocks 605, two sealing discs 606 and the oil guide seat 607 and is fixedly connected to another conical sealing block 605. The two conical sealing blocks 605 and the sealing discs 606 are symmetrically installed relative to the oil guide seat 607. The other end of the transmission rod 604 is inserted into the inner side of the spring pressure module 7. The surfaces of both ends of the oil guide seat 607 are provided with multiple guide holes. The return oil pipe connecting sleeve 602 is connected to the inner side of the two load control boxes 601 through multiple guide holes.

[0025] In summary, the main pump station 1 and the input end of the hydraulic booster body 10 are connected through two oil injection pipes, and the output end of the main pump station 1 and the hydraulic booster body 10 are connected through a return oil pipe. When the hydraulic booster body 10 is pressurized for oil leakage detection, the main pump station 1 is pressurized by the first pressure reducing valve 202 on the two oil injection pipes and then the combined flow is input to the inside of the hydraulic booster body 10. The two first pressure reducing valves 202 are connected through the first two-position three-way solenoid valve 201. The first two-position three-way solenoid valve 201 and the two first pressure reducing valves 202 form the upper rotary valve oil supply unit 2 and the lower rotary valve oil supply unit 3, which facilitates the dual-path delivery operation of hydraulic oil and expands the pressure range of hydraulic oil. The overflow valve 402 is used to overflow the maximum pressure of the return oil pipe, and the flow rate of the return oil pipe is regulated by the first throttle valve 401 and the second throttle valve 403. The servo valve 5022 in the two automatic input control units 502 controls the servo cylinder 5021 based on the monitoring of the second pressure reducing valve 5023, thereby satisfying the automatic opening and closing control of the oil injection pipe by the automatic input control unit 502. At the same time, the manual input control unit 501 can manually open and close the oil injection pipe. Specifically, pushing the control handle 5013 causes it to rotate relative to the control mounting housing 5011 via a pin, and linearly pushes the push rod 5014 via the transmission slider 5016. Thus, the push rod 5014 can manually open and close the input end of the hydraulic booster body 10. The positioning knob 5012 is inserted into the inner side of the middle of the control handle 5013, which facilitates the stability of the control handle 5013 when it is in the middle of its stroke. When the positioning handle 5015 rotates, it drives the positioning tooth block 5017 to engage with the control handle 5013, thereby enabling fine adjustment of the swing angle of the positioning tooth block 5017.

[0026] When the hydraulic oil in the main pump station 1 returns to the inside of the main pump station 1 through the return oil pipe at the output end of the hydraulic booster body 10, the hydraulic oil in the return oil pipe is pressurized by the output pressurization module 6 and the spring pressurization module 7. Then, the pressure of the hydraulic oil in the hydraulic booster body 10 can be adjusted by the oil injection pipe, the output pressurization module 6 and the spring pressurization module 7 to meet the requirements of oil leakage pressure control in the hydraulic booster body 10. The heating oil tank 902 is equipped with an electric heating resistance wire, so that the auxiliary pump station 901 draws the hydraulic oil in the main pump station 1 into the heating oil tank 902 for heating, and then delivers it to the inside of the hydraulic booster body 10 through the two oil injection pipes. The ball valve 801 can extract and measure the returning hydraulic oil, or the second two-position three-way solenoid valve 802 and flow meter 803 can monitor the flow rate of the returning hydraulic oil. By comparing the input and output hydraulic oil flow rates of the hydraulic booster body 10, the hydraulic booster body 10 can be tested for oil leakage at normal and high temperatures.

[0027] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
