Embodiment
In the description of the invention, it is to be understood that the orientation or position relationship of the instruction such as term " interior ", " outer " are
Based on orientation shown in the drawings or position relationship, it is for only for ease of the description present invention and simplifies description, rather than instruction or dark
Show that the device of meaning or element there must be specific orientation, with specific azimuth configuration and operation, thus it is it is not intended that right
The limitation of the present invention.
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 of two element internals, can be joined directly together, can also be indirectly connected by intermediary, for
For one 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 present invention is made further with reference to embodiment and accompanying drawing
Bright, the content that embodiment refers to not is limitation of the invention.
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 provided with separate main pump rotor chamber and auxiliary pump turn
Sub- chamber, is provided with main pump rotor 3 in the main pump rotor chamber, and the auxiliary pump rotor chamber is interior to be provided 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, a naturally also important indicator for directly affecting engine reliability,
Especially it is emphasized that 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 need 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, main pump oil discharge outlet 3b and auxiliary pump oil inlet 4a draining oil groove 6 are communicated with the pump housing 1.
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 larger rotary resistance to the bent axle of engine, separately
On the one hand, too high 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 rotating shaft axis hole of connection oil sump and auxiliary pump rotor 4 is additionally provided with the pump cover 2.
Because auxiliary pump uses not as the main pump oil unit under normal condition, therefore 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 rotating 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 provided 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, steam vent 8 is additionally provided with the valve body 7a, the steam vent 8 connects main pump inlet port 3a.In order to protect
Demonstrate,prove the normal work of relief valve, it is necessary to discharge, therefore send out for air pressure caused by the inner plunger 7b of relief valve 7 normal movement
A person of good sense is provided with steam vent 8 on valve body 7a
Above-described embodiment is the preferable implementation of the present invention, and in addition, the present invention can be realized with other manner, not taken off
It is any on the premise of conceiving from the technical program obviously to replace within protection scope of the present invention.
In order to allow those of ordinary skill in the art more easily to understand improvements of the present invention relative to prior art, this
Some accompanying drawings of invention and description have been simplified, and for the sake of clarity, present specification is omitted some other members
Element, those of ordinary skill in the art should be aware that these elements omitted also may make up present disclosure.
