Embodiment
In the description of the utility model, it is to be understood that the orientation of the instruction such as term " interior ", " outer " or position are closed
It is to be described based on orientation shown in the drawings or position relationship, to be for only for ease of description the utility model and simplifying, rather than
Indicate or imply that signified device or element there must be specific orientation, with specific azimuth configuration and operation, therefore cannot
It is interpreted as the limitation to the utility model.
In addition, term " installation ", " connected ", " connection " should be interpreted broadly, for example, it may be mechanically connecting or being electrically connected
Connect or the connection inside two elements, can be directly connected, can also be indirectly connected by intermediary, for
For those of ordinary skill in the art, the concrete meaning of the term can be understood as the case may be.
For the ease of the understanding of those skilled in the art, the utility model is made with reference to embodiment and attached drawing further
Explanation, the content that embodiment refers to not is restriction to the utility model.
As shown in Figure 1, a kind of birotor lubricating oil pump, it can be ensured that engine location occurs to be still able to ensure during larger inclination
The good lubrication of engine, including the pump housing 1, pump cover 2, the pump housing 1 is interior to be equipped with mutually independent main pump rotor chamber and auxiliary pump turn
Sub- chamber, is equipped with main pump rotor 3 in the main pump rotor chamber, and the auxiliary pump rotor chamber is interior to be equipped with auxiliary pump rotor 4, on the pump cover 2
It is provided with main pump inlet port 3a, main pump oil discharge outlet 3b, auxiliary pump inlet port 4a and auxiliary pump oil discharge outlet 4b, the main pump inlet port 3a companies
Connect the left side oil pipe of engine oil pan bottom, the main oil gallery of the main pump oil discharge outlet 3b connections engine, the auxiliary pump oil suction
The right side oil pipe of mouth 4a connection engine oil pan bottoms, the auxiliary pump oil discharge outlet 4b connect the oil sump of the main pump side,
The main pump rotor 3 and auxiliary pump rotor 4 drive by the master gear on engine crankshaft.
In the practical application of engine, how to ensure under critical conditions that engine is still able to obtain good lubrication to be
One examination very important index of engine performance, is naturally also an important indicator for directly affecting engine reliability,
Especially it is emphasized that the prior art did various trials for the lubrication under the tilt condition of engine, but all
Fail it has been proposed that using this thinking of dual pump design, its reason essentially consists in dual pump design and necessarily brings certain power to disappear
Consumption, to ensure that two independent pump housings obtain good lubrication, often needs to set complex lubricating pipe, power damage again
The problem of consumption and the arrangement of pipeline inherently evade very much for engine, and inventor then courageously contemplates and it is double to employ
Rotor design, and also especially emphasize for two rotors to be horizontally arranged at the side of engine, allow main pump rotor and auxiliary pump to turn
The armature spindle of son is parallel with engine crankshaft space, and the main pump rotor 3 and auxiliary pump rotor 4 in rotation are with regard to that can overcome engine to operate
Middle uneven shake（This structure design is rather similar to the balance shaft design of some engines）, inventor this feels free to try
Undoubtedly breach the bottleneck of existing technical staff and make important breakthrough.
Further, the pump housing 1 is equipped with the draining oil groove 6 of connection main pump oil discharge outlet 3b and auxiliary pump oil inlet 4a.
In the state of normal operation, i.e. engine not run-off the straight, at this time the main pump of the lubricating oil pump be possible to meeting
There is the state of oil extraction hypertonia, if oil extraction hypertonia will produce the bent axle of engine larger rotary resistance, separately
On the one hand, excessive oil extraction pressure can also be eventually converted into the interior energy of lubricating oil, cause oil outlet temperature also to raise, for starting
The lubricating oil viscosity of machine can impact, therefore, it is necessary to set pressure release passage for the oil discharge outlet of main pump.
Further, the oilhole 5 of the shaft axis hole of connection oil sump and auxiliary pump rotor 4 is additionally provided with the pump cover 2.
Since auxiliary pump uses not as the main pump oil unit under normal condition, actual auxiliary pump rotor 4
Armature spindle does not undertake larger load, and therefore, directly it can be lubricated using oil sump inner fluid, so invention
People has opened up the oilhole 5 of the shaft axis hole of connection oil sump and auxiliary pump rotor 4 on pump cover 2.
Further, a relief valve 7 is additionally provided with the pump housing at main pump oil discharge outlet 3b, the relief valve 7 includes valve body
Drain tap 7d, the drain tap 7d are equipped with the middle part of 7a and plunger 7b in valve body 7a and plunger spring 7c, the valve body 7a
Connect the main pump inlet port 3a.- main pump the meeting of being possible to of lubricating oil pump is caused the problem of foregoing to prevent draining oil groove 6 from blocking
There is the state of oil extraction hypertonia, inventor is further provided with relief valve on the pump housing.
Further, exhausting-gas hole 8 is additionally provided with the valve body 7a, the exhausting-gas hole 8 connects main pump inlet port 3a.In order to protect
Demonstrate,prove the normal work of relief valve, it is necessary to which the air pressure for the normal movement generation of 7 inner plunger 7b of relief valve discharges, therefore sends out
A person of good sense is provided with exhausting-gas hole 8 on valve body 7a
Above-described embodiment is the preferable implementation of the utility model, and in addition, the utility model can be with other sides
Formula is realized, any on the premise of the technical program design is not departed from obviously to replace in the protection model of the utility model
Within enclosing.
