It please coordinate with reference to Fig. 5 to Fig. 7, the multistage variable oil pump of the attached drawing display present invention is original state, at this time
Since the oil pressure that goes out at the fuel-displaced area 104 is in general use state, the adjusting spring 33 and the driving spring 43
Elastic force, respectively so that the adjusting valve body 34 be resisted against the portion of the first class 116 and the driving valve body 44 be resisted against this second
Portion of class 124, and not yet formed it is any go out oil pressure and fuel-displaced flow on adjustment.
It please coordinate with reference to shown in Fig. 8 and Figure 15, the fuel-displaced area 104 is lifted in order to cater to the demand of external use condition
Outlet oil pressure 51 and rate of discharge 52, make the operating characteristics curve of the present invention be in first segment variable range 501, the fuel-displaced area 104
Pressurization oil by the second unicom road 122 push against the driving valve body 44 end, to overcome the elastic force of the driving spring 43, make
The driving valve body 44 moves towards the driving end plug 42 away from the portion of the second class 124 and is resisted against the driving end plug 42,
In 44 displacement process of driving valve body, which is influenced by the driving valve body 44 and rotates an angle, and it is outer thus to change this
Meshing relation between rotor 22 and the internal rotor 23, and between the interior teeth portion of the outer rotor 22 and the outer toothed portion of the internal rotor 23
Gap, and then adjust the oil flow rate that inner and outer Rotator rotary presser is delivered to outlet.
It please coordinate with reference to shown in Fig. 9, Figure 10 and Figure 15, be in when of the invention under 502 state of second segment variable range, this means,
External condition for the demand amplitude of pressurization machine oil of the present invention if first segment variable range 501 is not urgent when, at the fuel-displaced area 104
Outlet oil pressure 51 still be slightly above first segment variable range 501 outlet oil pressure 51, also, the driving valve body 44 be held against in
While the driving end plug 42, as shown in figure 8, the fuel-displaced area 104 pressurization oil push against the adjusting valve body 34 away from this first
Portion of class 116, in 34 displacement process of valve body is adjusted, which corresponds to wherein one by-pass prot 119 in position,
Therefore the part in the fuel-displaced area 104 pressurization oil is sequentially from the sluice way 113, by-pass prot 119, the annular groove 341, wherein one return port
118 and the reflux road 117 and backflow to the Ru You areas 103, as shown in figure 3, the pressurization oil stream amount for returning the fuel-displaced area 104 by drawing
Technological means, accordingly to adjust the corresponding outlet oil pressure 51 of each rotating speed under 502 state of second segment variable range and rate of discharge 52
Adjustment amplitude.
It please coordinate with reference to shown in Figure 11, Figure 12 and Figure 15, when external condition exports the demand of oil level for the present invention
When having further lifting, and the operating characteristics curve of the present invention is set to be in rate of discharge increase in demand area 503, at this time, this is fuel-displaced
The pressurization oil in area 104 will further bestow 34 pressure of adjusting valve body, the adjusting valve body 34 is re-directed towards the adjustable side
32 displacements are filled in, and make the annular groove 341 away from the by-pass prot 119, so that closing pressurization oil in the sluice way 113 is directed to this time
Discharge orifice 118 and return to the passage in the Ru You areas 103, therefore the fuel-displaced area 104 outlet oil pressure 51 and rate of discharge 52 be able to greatly
The growth of amplitude, to meet the needs of external condition is for oil level and its pressure.
It please coordinate with reference to shown in Figure 13 to Figure 15, when the required pressurization oil mass of external condition downgrades a little, and in the
When in the state of three segment variable areas 504, still, outlet oil pressure 51 and rate of discharge 52 are still higher than rate of discharge increase in demand area
503 outlet oil pressure 51 and rate of discharge 52, at this time, the pressurization in the fuel-displaced area 104 oil push against the adjusting valve body 34 to against
In the adjusting end plug 32, then the subregion of another by-pass prot 119 is not covered by the adjusting valve body 34, thus makes this draw
Pressurization oil in runner 113 be able to from the by-pass prot 119, another return port 118 and stream returns to the Ru You areas 103, at the same time should
Pressurization oil in first room 115 is also back to the Ru You areas 103 by another return port 118, makes outlet oil pressure 51 and outlet
Flow 52 can adjust the amplitude of lifting in response to demand.
In the present invention, by the sluice way 113 of the housing 10, two return ports 118 and two by-pass prots 119 etc. guiding
The structure of machine oil flow direction, and coordinate the regulating valve 30 and the assembling of the driving valve 40 so that the driving valve 40 drives the pressurization group
