[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-2 The embodiment of the utility model provides a technical solution: a compact and lightweight medium and high pressure filter, comprising a device body 1, wherein the device body 1 comprises a filter cartridge 2, a filter seat 3 and a filter element 4, wherein the filter element 4 is installed inside the filter cartridge 2, and the filter cartridge 2 is installed at the bottom of the filter seat 3 by means of threads;

[0020] The problem is solved, the filter seat 3 includes a rectangular structure, an oil inlet 5 and an oil outlet 6 are opened on one side of the filter seat 3, the oil inlet 5 and the oil outlet 6 are located on the same side, a plug 8 is installed in the oil outlet 6, and a connecting threaded port 7 is opened at the bottom of the filter seat 3, the filter seat 3 can be installed on the filter cartridge 2 by threading, thereby improving the convenience of connecting the two.

[0021] Furthermore, the filter cartridge 2 has a cylindrical structure, and the interior of the filter cartridge 2 is a hollow structure. A first sealing ring 9 and a PTFE support ring 10 are provided at the connection between the filter cartridge 2 and the filter seat 3. The first sealing ring 9 is located at the top of the PTFE support ring 10. The first sealing ring 9 and the PTFE support ring 10 at the connection between the filter cartridge 2 and the filter seat 3 can effectively improve the sealing of the two, and further prevent oil leakage.

[0022] Differently, the filter element 4 is of cylindrical structure, a second sealing ring 11 is provided at the joint between the top of the filter element 4 and the filter seat 3, and a bypass valve 12 is installed at the bottom of the filter element 4.
