For the flow in the further control working oil path, second modulating valve 5 that also comprises embodiment illustrated in fig. 1, it is connected between the Working oil cooler 7 of the second outlet 33 of the first modulating valve 3 and working oil path.
More specifically, the second modulating valve 5 has the structure that is similar to the first modulating valve 3, and it has the second import 51, the second controlling mechanism, the 3rd outlet the 52 and the 4th outlet 53.The second import 51 of the second modulating valve 5 and the Working oil cooler of working oil path 7 are connected by pipeline, the 3rd outlet 52 of the second modulating valve 5 is the spillage oil outlet, the 4th outlet 53 of the second modulating valve 5 is connected with the second outlet 33 of working oil path, the first modulating valve 3, and the second controlling mechanism is used for regulating the size of the 3rd outlet 52.
In the present embodiment, the second controlling mechanism of the first controlling mechanism of the first modulating valve 3 and the second modulating valve 5 is similar spring controlling mechanism, for example the first controlling mechanism of the first modulating valve 3 comprise adjusting nut 34, spool 35, be set in spool 35 outsides, have with second the outlet 33 openings that communicate 371 valve pocket 37 and Regulation spring 36, Regulation spring 36 is connected between adjusting nut 34 and the spool 35, change the upper-lower position of adjusting nut 34, namely can regulate the size of the area that communicates of the opening 371 of the second outlet 33 and valve pocket 37.The second controlling mechanism of the second modulating valve 5 comprises adjusting nut 54, spool 55 and Regulation spring 56, Regulation spring 56 is connected between adjusting nut 54 and the spool 55, change the upper-lower position of adjusting nut 54, namely can regulating spool 55 and the communicate size of area of the 3rd outlet 52.
In addition, the present embodiment also comprises the second gear pump 4 and motor 41.Motor 41 is connected to drive the second gear pump 4 with the second gear pump 4, the oil outlet of the second gear pump 4 is communicated with the oil outlet of the first gear pump 2, the first import 31 of the first modulating valve 3, and the second gear pump 4 and motor 41 are used for when hydraulic coupler body 13 does not start or lubricant oil appears providing when emergency situations is stopped transport in hydraulic coupler body 13.
During operation embodiment illustrated in fig. 1, the power of the first gear pump 2 comes from the rotation of driving gear shaft 11, and the first gear pump 2 sucks oil in the fuel tank, and oil enters the first modulating valve 3 by pipeline after by 2 pressurizations of the first gear pump oil content is joined.Oil by the first outlet 32 enters lubricating oil path, through entering the female pipe of lubricant oil after lubricant oil oil cooler 61, the filter 62 etc.Be connected to the less pipeline of diameter that leads to each bearing shell on female pipe, the usefulness of each bearing shell lubrication and cooling is provided.The second outlet oil of 33 by the first modulating valve 3 enters working oil path, after finishing moment and transmit by pump impeller 131, turbine 132, by entering working oil oil cooler 7 after scoop tube 15 sucking-offs (scoop tube 15 can be controlled the sucking-off oil mass by regulating aperture).By the second modulating valve (working oil modulating valve) 5 control working oil flows, the oil that flows through the 3rd outlet 52 is that spillage oil directly flows back to fuel tank at last.Oil by the 4th outlet 53 reenters the working oil circulation.
Particularly, and simultaneously referring to Fig. 2-Fig. 4, the outlet oil of the first gear pump 3 at first advances the first import 31 of the first modulating valve 3, if oil pressure is greater than a certain setting value X, then oil meeting jack-up spool 35, move by spool 35, the second outlet 33 is opened and is made part oil enter working oil path, and remaining oil flows into lubricating oil path through the first outlet 32.Oil pressure setting value X compresses Regulation spring 36 controls by adjusting nut 34.In Fig. 2, adjust adjusting nut 34 downwards, then Regulation spring 36 resiliently deformables strengthen, and setting value X increases thereupon, thereby the opening 371 of valve pocket 37 is reduced with the second outlet 33 areas that communicate, and the work oil mass of providing reduces.Otherwise to adjusted, then the X value reduces, and the work oil mass increases.When oil pressure reached certain value, oil pressure acted on the power that makes progress on the spool 35 and acts on power downward on the spool 35 greater than Regulation spring 36, so with spool 35 jack-up, like this, the opening 371 of the second outlet 33 and valve pocket 37 is connected.
