Embodiment

Below in conjunction with accompanying drawing preferred forms of the present utility model is specifically described:

Referring to Fig. 1 to Fig. 5, this modularization machine oil cooling filter comprises oil filter 1, machine oil cooler 2, filter block 3, hollow double threaded screw 4.

Oil filter 1 adopts rotary mounting engine oil filter, it comprises shell 1a, seal ring 1b, thread plate sub-assembly 1c, non-return valve block 1d, filter element part 1e, supported spring 1f, and there are circumferentially uniform 6 oil inlet hole 1h of fuel-displaced tapped hole 1g, center region at the center of thread plate sub-assembly 1c.

Machine oil cooler 2 is the disc type oil cooler, it comprises shell 2a, place the cooled wafer group assembly in it, place the seal ring 2b of its downside, cooled wafer group assembly is by stacked successively and constitute by five water-stop sheet 2e, 6 layers of disc type cooled wafer group 2f at interval up and down, also respectively be provided with a water-stop sheet 2e between the disc type cooled wafer group 2f of the shell 2a and the superiors and the undermost disc type cooled wafer group 2f, shell 2a, water-stop sheet 2e, the center region of cooled wafer group 2f forms the vertical up and down passage 2g that connects, peripheral cavity between shell 2a and water-stop sheet 2e and the cooled wafer group 2f outside forms cooling water channel 2h, a relative side of shell 2a upper and lower end face respectively has a hydraulic fluid port (omitting the piece number of two hydraulic fluid ports in the accompanying drawing), the inside of water-stop sheet 2e and cooled wafer group 2f communicates and forms the oil duct 2i that communicates up and down with described two hydraulic fluid ports, the water supply connector 2d and the water output connector 2c that communicate with cooling water channel 2h are arranged on the sidewall of shell 2a, and passage 2g, cooling water channel 2h, oil duct 2i is isolated each other.

Oil suction chamber 3a arranged in the filter block 3, go out oil pocket 3b, control chamber 3c, the pressure-limit valve 3d that communicates with oil suction chamber 3a, control chamber 3c respectively is housed on the filter block 3, also be equipped with respectively with oil suction chamber 3a on the filter block 3, go out the bypass valve 3e that oil pocket 3b communicates, have four on the filter block 3 and be used for the mounting hole 3f that is connected with motor.

One end of double threaded screw 4 spin with filter block 3 and with go out that oil pocket 3b communicates, the other end pass passage 2g after spinning one be communicated with (piece number that omits fastening screw nut in the accompanying drawing) with fuel-displaced tapped hole 1g with fastening screw nut and this end that shell 2a upper-end surface closely contacts, seal ring 1b closely contacts with the upper-end surface of shell 2a, seal ring 2b closely contacts with the upper-end surface of filter block 3, make oil filter 1, filter block 3 be posted by connecting with machine oil cooler 2 liquid sealings respectively, oil suction chamber 3a communicates with oil inlet hole 1h through oil duct 2i.
