Setting, i.e. commutation component 4 ' are parallel and equidirectional with driving assembly 2 '.It is upward in motor shaft that the setting not only reduces hydraulic pump
Size, while motor radial dimension is also significantly reduced compared with the invaginating hydraulic pump in embodiment one.
In conclusion invaginating hydraulic pump provided by the invention can by opening up mounting hole, hydraulic seat on oil circuit shell
Disassembly is mounted in mounting hole the separation for realizing hydraulic package and the pump housing, not only facilitates the replacement of hydraulic package and during fabrication
The other component of hydraulic package and hydraulic pump can be used different materials and be made, and significantly reduce manufacturing cost, and invaginating
Mounting means then substantially reduces the volume of hydraulic pump.The flow direction of oil circuit component inner fluid is replaced by setting commutation component,
The opposite oil circulation of both direction is formed, so that executing agency can automatically move back and forth, without manual operation, significantly
Improve the working efficiency of hydraulic pump.
Although the present invention is disclosed above by preferred embodiment, however, it is not intended to limit the invention, this any known skill
Skill person can make some changes and embellishment without departing from the spirit and scope of the present invention, therefore protection scope of the present invention is worked as
Subject to claims range claimed.
