Embodiment Construction

[0028] In order to make the purpose, technical solution and advantages of the application more clear, the technical solution in the embodiment of the application will be described in more detail below in conjunction with the drawings in the embodiment of the application.

[0029] A low-resistance integrated lubricating oil filter, such as Figure 5-7 As shown, it includes a casing 1, an oil filter element 22, a one-way valve 2, a bypass valve 3 and a lubricating oil filter frame 4. The housing 1 is provided with an inner chamber for containing filter elements, the oil filter element 22, the one-way valve 2, the bypass valve 3 and the lubricating oil filter frame 4 are all arranged in the inner chamber, and the middle part of the housing 1 is provided with a lubricating oil inlet, and the housing 1 There is a lubricating oil outlet on the top. The oil filter element 22 is arranged coaxially along the center line of the casing 1 of the casing 1, and the lubricating oil filter f...

Abstract

The invention relates to the field of lubricating oil systems, and in particular relates to a low-resistance integrated lubricating oil filter. A first piston rod is arranged to be of a hollow cylinder structure, and a first spring is arranged between the first piston rod and the inner wall of a lubricating oil filter framework, so that an additional limiting structure does not need to be arranged on the first spring; due to the reduction of the limiting structure, the flow area of lubricating oil in the one-way valve is increased, the bending degree of a lubricating oil flow path is reduced, and the resistance is reduced; meanwhile, the first piston rod is in sliding fit with the inner wall of the lubricating oil filter framework, and a guide structure in axial fit is reduced, so that the axial space reserved by the one-way valve is increased, the formation of the sliding valve is increased, the compression of the spring does not influence the flowing area of the lubricating oil, the flowing area of the lubricating oil is further increased, and the resistance loss of the lubricating oil is further reduced.

Description

technical field [0001] The application belongs to the field of lubricating oil systems, in particular to a low-resistance integrated lubricating oil filter. Background technique [0002] The aviation gas turbine engine lubrication system is an important part of the aviation gas turbine engine, mainly responsible for the lubrication of the engine's high and low pressure rotor fulcrum bearings, transmission gears and other components. The lubricating oil filter is an accessory to ensure the cleanliness of the lubricating oil system. It is mainly used to filter the lubricating oil in the engine lubrication system and remove impurities to ensure the normal use of the lubricating oil in the system. Due to the low oil supply pressure of the aero-engine lubricating oil, in order to ensure that the engine lubricating oil is normally supplied to each bearing cavity to participate in lubrication and heat exchange, the lubricating oil accessories and pipeline resistance on the lubricat...
