Embodiment 1
[0045] This embodiment provides a filter such as figure 1 As shown, it includes an upper tank 11, a lower tank 12, a base 2 and a control valve assembly; specifically, the base 2 is fixedly arranged between the upper tank 11 and the lower tank 12, and the base 2 is provided with a The oil inlet pipeline 21, the oil return pipeline 22 and the oil outlet pipeline 23, the oil inlet pipeline 21 is communicated with the oil outlet pipeline 23, the oil outlet pipeline 23 is communicated with the low pressure oil pump, and the low pressure oil pump can pump oil to the common rail system; the control valve assembly is arranged in the On the base 2, the control valve assembly can control the oil inlet pipeline 21 to alternatively connect the lower tank 12 and the main oil tank, or connect the upper tank 11 and the auxiliary oil tank; the control valve assembly can control the oil return pipeline 22 to alternatively connect to the main oil tank and the common rail system, or the auxilia...
Embodiment 2
[0066] This embodiment provides a filter, and the overall structure of the filter provided in this embodiment is basically the same as that of the filter in Embodiment 1, and only some settings of the control valve assembly are different, and this embodiment does not The same structure as that of the first embodiment will be described in detail.
[0067] The difference between this embodiment and the first embodiment is that, as Figure 8 As shown, the oil inlet control valve and the oil return control valve are both two-position three-way solenoid valves, and the three channels of the first two-position three-way solenoid valve 36 are respectively connected with the upper oil inlet port 211, the lower oil inlet port 212 and the oil inlet pipe. Road 21 is connected, and the three channels of the second two-position three-way solenoid valve 37 are respectively connected with the upper oil return port 221, the lower oil return port 222 and the oil return line 22; the number of s...
