Embodiment Construction
[0046] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0047] The present invention provides an electronically controlled split unit pump, which includes a pump body 8 and a valve body 23. The valve body 23 is fixed on the side of the pump body 8 by bolts. The outlet of the oil passage communicates with the pump nozzle oil passage 29, the plunger chamber, and the high-pressure oil passage D in the valve body 23; the low-pressure oil passage in the pump body 8 communicates with the low-pressure oil passage in the valve body 23.
[0048] Such as Figure 13As shown, the high-pressure oil passage in the pump body 8 is divided into oil passage I30, oil passage II31 and oil passage III32; Road III32 is arranged obliquely, one end communicates with high-pressure oil passage D in valve body 23, and there is a bend II34 between the two, and the other end communicates with oil passage II31; oil passage II31 is vertical...
