Particularly, described first passage is identical with the quantity of piston with the quantity of second channel, and first passage and second channel replace uniform array.
Again particularly, described first passage, second channel and chamber of confluxing are columnar hollow body, and the axis in chamber of confluxing and the axis coaxle of spool are arranged.
More specifically, described chamber of confluxing can only be in communication with the outside by first passage and second channel.
Advantageously, described spool cross section is in axial direction " work " font.
Advantageously, described spool is also provided with the vent hole running through spool, and described vent hole is between first passage and second channel, and described vent hole does not communicate with first passage or second channel.
Advantageously, described spool axially runs through along it 4 tapped holes.
Beneficial effect
In line with simple and reliable principle, the end of the first passage of spool is communicated with by chamber of confluxing with the end of second channel by the utility model, achieves multiple containing cavities and shares a spool, decrease number of spare parts, simplify transmission link, improve stability and the reliability of device.
The head end of first passage and the head end of second channel are arranged to the outer circumferential face extending to spool along the radial direction of spool, achieve being communicated with of conflux chamber and containing cavities, and chamber of confluxing is communicated with extraneous.
First passage, second channel and chamber of confluxing are set to columnar hollow body, manufacture and the processing of part can be facilitated.
Spool cross section be in axial direction set to " work " font and multiple vent hole is set on spool, not only alleviating the weight of transfer device, realize light-weight design, also helping the heat radiation of device.
