Problems solved by technology

[0004] However, setting hydraulic components independently will increase the number of hydraulic components in the hydraulic system, thereby increasing the complexity of the hydraulic system, which is not conducive to the installation of the hydraulic system
In addition, because each hydraulic component works independently, there is a lack of correlation between them, so the cooperation between various hydraulic components is relatively difficult, thereby reducing the performance of the hydraulic system
In addition, in the prior art, each independent hydraulic component needs to be connected through pipelines, and such a connection is likely to cause leakage, so every additional independent hydraulic component will increase the failure rate and leakage rate of the hydraulic system

Embodiment Construction

[0022] Such as figure 1 As shown, in one embodiment of the present invention, the left end of the main body 2 is an oil inlet 21 , and the right end is an oil outlet 22 . A built-in spherical check valve is embedded at the oil inlet 21 of the main body 2, and the check valve core 5 of the check valve is pressed against the oil inlet channel 23 through the gland 4, so that the oil only It can flow from left to right, block the reverse transmission of pressure shock to the hydraulic pump, and protect the hydraulic pump. The one-way valve spring 6 of the one-way valve is a return spring embedded with a spherical one-way valve, which can control the position of the one-way valve spool. The first sealing ring 3 seals the gap between the main body 2 and the gland 4 .

[0023] Such as figure 1 As mentioned above, a piston accumulator is embedded in the upper end of the main body 2 , and the accumulator includes an accumulator housing 15 and an end cover 13 . The end cover 13 cove...

Abstract

The invention discloses a hydraulic device which comprises a main body, wherein an oil inlet is arranged at one side of the main body, and the other side of the main body is provided with an oil outlet. The hydraulic device is characterized in that a one-way valve is embedded in the oil inlet, an energy accumulator is embedded in the upper end of the main body, a filter is connected to the main body, the one-way valve is connected with an inlet of the filter through an oil inlet channel, the oil outlet is connected with an outlet of the filter through an oil outlet channel, therefore, the oil inlet channel, the filter and the oil outlet chancel are serially connected together to form a main passage of the hydraulic device, and the energy accumulator is connected in parallel to the oil inlet channel through a runner in the main body. The hydraulic device can realize integrated functions of hydraulic system pressure ripple rejection, hydraulic medium filtration and hydraulic pump pressure impaction protection, thereby reducing pipeline connection among components, eliminating leakage and improving system reliability.

Description

technical field [0001] The invention relates to the technical field of airborne hydraulic energy systems, in particular to a hydraulic device suitable for aircraft hydraulic energy systems. Background technique [0002] The aircraft hydraulic energy system is the core of the aircraft hydraulic system. The hydraulic pump converts the mechanical energy into the pressure energy of the fluid, and transmits it to each functional subsystem through the working fluid to complete the predetermined task. In the existing aircraft hydraulic system, in order to protect the system itself, it is necessary to suppress the pressure pulsation of the hydraulic system and protect the pressure shock of the hydraulic device. In the current aircraft hydraulic energy system, the hydraulic system pressure pulsation suppression, hydraulic medium filtration, and hydraulic pump pressure shock protection are realized by setting independent hydraulic components. [0003] In an embodiment of the prior ar...
