Moving axis is fixedly connected with swash plate, and the power transmission shaft top is provided with cotter way, and the plunger side is provided with piston shoes, and the plunger bottom sets
There is spring, the spring inner is provided with guide rod, and the piston shoes side is provided with boots groove, and the boots groove is connected with piston shoes activity, institute
State boots groove side and thickening plate is installed, the thickening plate is fixedly connected with boots groove.
Further, the cover internal is provided with bolt.
Further, the pump body is provided with bearing.
Further, the pump body is provided with valve plate, and baffle ring is provided with inside the valve plate.
Further, the plunger side is provided with connecting rod, and the connecting rod side is provided with conduit.
Compared with prior art, the beneficial effects of the utility model are：This kind of low noise cam-type axial piston pump, due to
Using swash plate and power transmission shaft fixed form, both reduces costs, and with good seamlessly transitting property, because swash plate angle is fixed, institute
Not have very big pressure differential between each two plunger, so go out to be formed high pressure differential in inlet port, coordinate pump housing front end
Space is lengthened, residual noise can be effectively reduced, makes the premium properties of the existing conventional pump of the plunger displacement pump, noise can reduced again and is adapted to now
Generation production needs.
