Show, and the state that the tilt angle of swash plate 35 is maximum rating i.e. 12 ° is shown in figures 7 and 8.
On the basis of Fig. 5, firstly, drive shaft 90 will rotate under the action of driving portion.When drive shaft 90 is to arrow
1. direction when being rotated, the cylinder block 50 being fixed in drive shaft 90 will also rotate together.Cylinder block 50 is by edge
Direction identical with drive shaft 90 rotated, 2. arrow has indicated the direction of rotation of cylinder block 50.At this point, cylinder block 50
Rotary shaft be drive shaft 90.
When cylinder block 50 rotates, the piston assembly 70 being inserted on cylinder block 50 will rotate together.Because living
The piston main body 71 of plug assembly 70 is inserted into inside the cylinder-bore 55 of cylinder block 50, therefore in the cylinder block 50 rotation,
Piston assembly 70 will also be driven and rotate together.The piston assembly 70 being respectively inserted into the multiple cylinder-bore 55
It will rotate simultaneously.
In addition, the retaining ring 80 being connected in piston assembly 70 will also carry out together when piston assembly 70 is rotated
Rotation.Because the globe joint 73 being provided in the piston assembly 70 is also connected while being connected in piston main body 71
It is connected in retaining ring 80, therefore can finally make piston assembly 70 that retaining ring 80 be driven to be rotated together.Each globe joint 73
Retaining ring interconnecting piece is pressed into the retaining ring hole 82 of the retaining ring 80 with rotatable state.Because retaining ring 80 can be relative to oblique
Disk 35 carries out independent rotation, therefore will be rotated relative to fixed swash plate 35.3. arrow represents the rotation of retaining ring 80
Direction.
When retaining ring 80 is rotated, retaining ring 80 will be in the state of maintaining the angle parallel with the inclined surface 36 of swash plate 35
It is rotated.This is because retaining ring 80 can maintain to be adjacent to the shape on the swash plate 35 by the rotary joint of swash plate 35
State, as a result, the retaining ring 80 can not shake in rotary course and with right with the swash plate 35 inclined surface 36
The certain tilt angle answered is rotated.Whereby, can prevent the course of work guide ring 80 of pump with basic rotary shaft
The phenomenon that arbitrarily being rotated or tilted centered on other unrelated rotary shafts.
At this point, the movement of the piston assembly 70 rotated together with retaining ring 80 will receive the influence of inclined surface 36, such as
In Fig. 5 and situation shown in fig. 6, because swash plate 35 is in parallel state and does not tilt, piston assembly 70 will not
Carry out elevating movement (arrow 4. direction).That is, being applicable in fluid pump of the invention will not in the state of as shown in figs.5 and 6
Execute pumping function.
But under heeling condition as shown in Figure 7 and Figure 8, because the retaining ring 80 can be with the inclined surface of swash plate 35
36 maintain inclined state together and are rotated, therefore the piston assembly 70 rotated together with retaining ring 80 will pass through inclination
Face 36 carries out elevating movement.
It, will be along when being moved to the right while rotating positioned at the piston assembly 70 in left side originally on the basis of Fig. 7
Inclined surface 36 rises to relatively high position is mobile.As a result, the piston main body 71 of piston assembly 70 will be to cylinder block 55
Medial movement.Next when continuing rotation, piston assembly 70 will be moved along inclined surface 36 to relatively low position again
It is dynamic to decline.4. arrow represents the lifting direction of piston assembly 70.
In addition, in the lifting process of piston assembly 70, piston assembly 70 will carry out compressing/extensional motion and in this process
In fluid is compressed or is sucked.The fluid being present in inside cylinder-bore 55 is pressed during piston assembly 70 rises
Contracting, and spued via the first connectivity slot 13 by the first valve port 18a.At the same time, the piston assembly 70 of decline will pass through
Two valve port 18b draw fluid into the second connectivity slot 13' and go out, and preparation compresses it in next stroke.
By the cylinder block 50, piston assembly 70 and the rotation of retaining ring 80, a series of actions as described above will be continuously performed, and
It is repeatedly completed sucking and discharge stroke whereby.
At this point, the first valve port 18a or duaspiracle mouth 18b according to the direction of rotation of drive shaft 90, on shell 10,30
Entrance or the outlet of fluid can be converted to.That is, on the basis of specific piston assembly 70, if when cylinder block 50 is along up time
The needle direction progress of piston assembly 70 compression movement when being rotated, then when cylinder block 50 is rotated counterclockwise
Shi Suoshu piston assembly 70 will carry out extensional motion.Whereby, the first valve port 18a and duaspiracle mouth 18b can be made to spit
It is converted on the direction of fluid or sucking fluid out.This is under the structure that swash plate 35 is fixed and cylinder block 50 rotates
The advantages of realization, can by the direction of rotation to drive shaft 90 is converted simply implement it is hydraulic formed direction turn
It changes.
In addition, roller ball 74 is adjacent to swash plate 35 equipped with roller ball 74 in the retaining ring interconnecting piece of globe joint 73
Inclined surface 36 on.The roller ball 74 in the rotary course of piston assembly 70 for reducing globe joint 73 and swash plate 35
Friction between inclined surface 36.
Next, to the mistake that the tilt angle of swash plate 35 is converted into state as shown in Figure 7 from state as shown in Figure 5
Journey is illustrated.Firstly, operating personnel can lift swash plate 35 and pushing tilt adjusting section 100 to the direction of swash plate 35.
That is, tilt adjusting section 100 will be along the spiral shell of assembly hole 33' when rotating tilt adjusting section 100 along the direction arrow A in Fig. 6
Line carries out linear movement and the direction B into Fig. 8 rises.Whereby, the contact head 105 of the tilt adjusting section 100 will lift tiltedly
The bottom surface of disk 35, and swash plate 35 will be pivoted about with the rotary shaft 34' of bracket 34 and its tilt angle is increased.
At this point, user can be adjusted by the degree of rotation to tilt adjusting section 100, and accurately by swash plate 35
Tilt angle be adjusted to required state.For this purpose, tilt adjusting section 100 when by the way that tilt adjusting section 100 rotating a circle
It is adjusted to certain degree to the direction of swash plate 35 distance outstanding, it can be by means of the number of revolutions pair of tilt adjusting section 100
The variation degree of the tilt angle of swash plate 35 is adjusted.As described above, in the present embodiment, tilt adjusting section 100 by with it is oblique
Disk 35 directly against single component constitute.Tilt adjusting section 100 as described above can be during disengaging directly to swash plate
35 tilt angle is adjusted, therefore can simplify the structure being adjusted for the tilt angle to swash plate 35.
In contrast, opposite with the sequence of the above process for reducing the process of the tilt angle of swash plate 35.When to opposite
Direction when rotating tilt adjusting section 100, tilt adjusting section 100 will be gradually distance from swash plate 35 and makes the tilt angle of swash plate 35
It is gradually reduced.At this point, although side end, that is, contact head 105 of tilt adjusting section 100 still is able to by keeping and swash plate 35
Direct contact condition and continue to press on swash plate 35, but because be not fastened or connected on swash plate 35, tilt
Adjustment portion 100 can't direct pull swash plate 35 rotate it.
When tilt adjusting section 100 retreats, swash plate 35 will move naturally under the effect of the pressure of piston assembly 70
Until being in contact with tilt adjusting section 100, and reduce its tilt angle in the process.That is, becoming from state as shown in Figure 7
State more as shown in Figure 5.As described above, not needing for tilt adjusting section 100 to be directly connected in the present embodiment or consolidate
Determine onto swash plate 35, can also increased or decrease the tilt angle of swash plate 35.Whereby, it does not need to match and be ready for use on tilt adjusting section
100 labyrinths being directly or indirectly connected on swash plate 35 or feedback structure etc. for maintaining its tilt angle.
Unlike this, when in the tilt adjusting section 100 equipped with elastomeric element, user is not needed directly to inclination
Adjustment portion 100 is adjusted, but the tilt angle of swash plate 35 can be adjusted naturally using elastomeric element.That is, working as
Elastomeric element will be compressed when passing over stronger pressure by swash plate 35, and swash plate 35 will be with the rotary shaft of the bracket 34
It is rotated naturally to the direction that tilt angle reduces centered on 34', to realize the adjusting to its tilt angle.
In addition, as described above, user can be by adjusting when elastomeric element is supported by individual adjustment portion again
The adjusting in portion and the tilt adjusting section 100 and elastomeric element are adjusted to 35 direction of swash plate base altitude outstanding,
To be set to the minimum cant of swash plate 35.
