The card interface of cloth, the side of the cylinder body and inner sheet are equipped with multiple equally distributed inner side flow dividing structures, the inner side shunting
The side of structure is provided with outside flow dividing structure, and the fuel feed hole side of the inner sheet is provided with inlet port.
Further, the edge of the tooth mouth is provided with multiple dentation mouths, and the dentation mouth is evenly distributed in tooth mouth side
Edge.
Further, a diameter of 1CM of the plunger hole, a diameter of 3CM of the fuel feed hole.
Further, one end of the card interface is in contact with logical oil groove, and the other end touches with cylinder body side edge.
Further, the inlet port is arcuation, and runs through inner sheet.
Compared with prior art, the beneficial effects of the invention are as follows：This kind of integrated form Variable plunger pump distributing construction is designing
When, generally use odd number plunger is so the generation in order to avoid hydraulic pulsation, and the tank design is set using even number plunger
Meter, different logical oily distributing slots is designed on the distribution circle of cylinder body, hydraulic coupling caused by cylinder body is passed through different hydraulic fluid ports
Exported, the conversion of two relatively independent hydraulic system energies, this kind of integrated form variable can be completed by completing single cylinder body
The advantages of plunger pump distributing construction, with higher integration, has saved the design space of product, while improve the work(of product
Rate density, while reduce the manufacturing cost of product and the difficulty of processing of product.
