With the oil liquid pressure collective effect of plunger base, it is adjacent to swash plate；Pintle and transmission axis connection, operate synchronously；Wedge is assemblied in
In shell, flap type is installed in wedge, is adjacent to cylinder body under the action of valve spring, and flow function is realized together with pintle
Energy；Oil inlet loop is fixed on shell, and oil inlet is provided on oil inlet loop, is provided with oil outlet on wedge.
Compared with prior art, remarkable advantage of the invention are as follows: the present invention has rational design, and simple and compact for structure, rotation is used to
It measures small；Transmission shaft and swash plate use separate structure, can realize the seriation of product by changing swash plate angle；Flow mode selects
The mode that pintle is combined with flap type can be realized low speed heavy pressure operating condition reliably working.

On body 1, it is provided with oil inlet 5 on oil inlet loop, oil outlet 18 is provided on wedge.
Further, transmission shaft 2 and swash plate 7 use separate structure, and transmission shaft 2 drives swash plate 7 and the synchronous fortune of pintle 13
Turn.
Pintle 13 and flap type 14 realize flow function jointly.
The chuck 8 is connect with swash plate 7, plunger part 9, and centering 10 one end of bulb is connect with chuck 8, the other end and backhaul
The connection of 12 one end of spring, 12 other end of retracting spring are connect with pintle 13.
Below with reference to embodiment, the present invention is further described.
Embodiment
In conjunction with Fig. 1, a kind of axial plunger pump, by shell 1, transmission shaft 2, angular contact ball bearing 3, retaining ring 4, oil inlet loop 6,
