Embodiment

The utility model is described in further detail below in conjunction with the accompanying drawings：

With reference to shown in Fig. 1 and Fig. 2, the utility model includes shell 1, the filter core 10 being placed in shell 1, check-valves 8 and side Port valve 11；

The front end of shell 1 is provided with end cover 2, is connected between end cover 2 and shell 1 for detachable-type sealed；

The front end of filter core 10 is provided with oil-out and rear end is provided with oil inlet, and the oil-out of filter core 10 is provided with flowline 4 and end plate 3, flowline 4 leads to the center of filter core 10, one end of flowline 4 passed from the center of end cover 2 and the other end with Welded seal is connected between end plate 3, and installation gap is left between flowline 4 and end cover 2；

The front end of shell 1 is provided with the installing port 6 of pyramidal structure, and end plate 3 is the conical plate to match with installing port 6, is held Rubber sealant 5 is extruded between plate 3 and installing port 6, oil suction chamber 12 is formed between filter core 10 and shell 1, end cover 2 is set The oil inlet pipe 7 for leading to oil suction chamber 12 is equipped with, sealing connects between oil inlet pipe 7 and shell 1, between oil inlet pipe 7 and end cover 2 Connect；
