Embodiment

[0027] Such as figure 2 As shown, the oil filter assembly with its own bypass function, the self-cleaning oil filter assembly is used for aero-engine fuel accessories, and the self-cleaning oil circuit assembly includes a housing 21, an oil filter cover 22, and a filter screen assembly 23 , Hex head screw 24, sealing ring 25, sealing ring 26, spring 27, inlet oil circuit 28, outlet oil circuit 29, guide column 210, hexagon head screw 211, end cover 212. The filter screen assembly 23 is a hollow ring structure, which cooperates with the guide post 210 and is sealed by a sealing ring 26 . When the pressure difference between the inlet oil passage 28 and the outlet oil passage 29 is less than the pre-tightening force of the spring 27, the fuel enters the self-cleaning oil filter from the inlet oil passage 28, and reaches the outlet oil passage 29 through filtering by the filter assembly 23; When the pressure difference between the outlet oil passage 28 and the outlet oil passag...

Abstract

The invention relates to the technical field of valve structures, oil filters and the like, in particular to a safety valve and oil filter integrated assembly. The assembly comprises a shell (21), a filter screen assembly (23) and a spring (27), and the filter screen assembly (23) is installed in a cavity of the shell (21); an oil path (28) and an oil path (29) are formed in the shell (21), and the oil path (28) is communicated with one end A of the filter screen assembly (23) and is communicated with the oil path (29) from an inner cavity of the filter screen assembly (23) to a filter screen;one end of the spring (27) abuts against the other end B of the filter screen assembly (23), and the other end of the spring (27) abuts against an oil filter cover (22); and the oil filter cover (22)is connected with the shell (21) through a hexagon head screw (24) or a bolt. Compared with the prior art, a bypass valve does not need to be installed any more, one assembling hole system is omitted, one oil inlet way and one oil outlet way are omitted, and the application range of the self-washing oil filter is greatly expanded.

Description

technical field [0001] The present invention may relate to technical fields such as a valve structure and an oil filter, and particularly relates to an assembly integrating a safety valve and an oil filter. Background technique [0002] Such as figure 1 As shown, the existing self-cleaning oil filter and bypass valve are two components, the self-cleaning oil filter component and the bypass valve component are respectively installed on two sets of parallel oil circuits to achieve low temperature and increased pollutants. When the filter screen is blocked, the fuel can enter the lower stage oil filter through the bypass valve. [0003] When the pressure of the inlet oil passage 8 is greater than the pressing force of the spring 2, the oil pressure pushes the bypass valve 6 to move to the left. Enter the outlet oil passage 9. [0004] The existing self-cleaning oil filter and bypass valve require a large installation space, and require two installation holes and two sets of ...
