Description
Technical field
The present invention relates to lubricating system of IC engine technical field, in particular to a kind of pressure control based on fixed displacement lubricating oil pump
System processed.
Background technique
The effect of lubricating oil pump be each slipper that lubricating oil is supplied to engine to ensure its normal work,
Power source come from engine itself, the flow of exit end machine oil be it is directly proportional with the revolving speed of engine, due to engine
Revolving speed be a variable, between required flow of lubrication and engine speed be not be proportional relation, therefore, work as hair
Motivation works in high-velocity section, it may appear that the excessive problem of oil flow rate in turn results in the waste of engine power.
In the prior art, there are mainly two types of modes for the flow control of lubricating oil pump, and one is pressure release is arranged in the outlet end of pump
Valve, in this way, as revolving speed gradually rises, the outlet oil pressure of lubricating oil pump is stepped up when engine operation is in slow-speed of revolution section；
When engine enters high revolving speed section, the outlet oil pressure of lubricating oil pump is higher than the preset pressure value of relief valve, and relief valve is
It starts to work, discharge part machine oil, so that engine oil pressure be made to maintain a steady state value.But this mode only has pressure release work
With pressure regulation ability is very weak.
Another kind is the lubricating oil pump using changeable flow, and such lubricating oil pump is equipped with a mechanical flow control machine
Structure, which usually feeds back driving by the oil pressure of lubricating oil pump exit end, for example, vane-type variable flow machine oil
Pump.It is compared with first way, the lubricating oil pump of such changeable flow is conducive to improve the greasy property of high engine speeds section, but
Since the section that it is adjusted is few, oil pump capacity reacting condition postpones in operational process, and engine oil pressure fluctuation range is big, therefore simultaneously
The waste problem of the lubrication problem or engine power that cannot be fully solved when high engine speeds rotation.
Summary of the invention
The technical problem to be solved in the present invention is to provide the pressure controls based on fixed displacement lubricating oil pump that a kind of structure simplifies
System, the control system can be such that fixed displacement lubricating oil pump realizes and the consistent two-stage adjustable pressure mould of two-stage variable discharge capacity effect
Formula.
In order to solve the above-mentioned technical problem, the present invention adopts the following technical scheme: a kind of structure simplify based on fixed displacement

Before, the engine oil pressure in first pressure feedback cavity and second pressure feedback cavity is not enough to push plunger mobile, at this time fixed displacement machine
Pressure oil in oil pump oil outlet chamber is all flowed out from the oil discharge outlet of pressure limiting valve；When the engine oil pressure of main oil gallery reaches the level-one of setting
When vent pressure point, the pressure oil in first pressure feedback cavity and second pressure feedback cavity pushes the plunger of pressure limiting valve to be moved
It is dynamic, communicate oil outlet chamber interface with oil suction chamber interface, the partial pressure oil in fixed displacement lubricating oil pump oil outlet chamber passes sequentially through at this time
Oil outlet chamber interface, transporting room, oil suction chamber interface flow back into oil suction chamber, and another part pressure oil is then from the oil discharge outlet stream of pressure limiting valve
Out, to reduce output pressure；
When switch electromagnetic valve is switched to another working condition under control of the ecu, the P mouth of switch electromagnetic valve is not connected to A mouthfuls,
A mouthfuls are connected to T mouthfuls, and system enters the second level adjustable pressure stage, in this stage, without oil pressure in the first pressure feedback cavity of pressure limiting valve
Supply, second pressure feedback cavity are interior full of main oil gallery pressure oil；It is let out in the second level that the engine oil pressure of main oil gallery does not reach setting
Before pressure pressure point, the engine oil pressure in second pressure feedback cavity is not enough to push plunger mobile, and fixed displacement machine oil pumps out at this time
Pressure oil in oil pocket is all flowed out from the oil discharge outlet of pressure limiting valve；When the engine oil pressure of main oil gallery reaches the second level pressure release pressure of setting
When force, the pressure oil in second pressure feedback cavity pushes the plunger of pressure limiting valve to be moved, and makes oil outlet chamber interface and oil suction chamber
Interface communicates, and the partial pressure oil in fixed displacement lubricating oil pump oil outlet chamber passes sequentially through oil outlet chamber interface, transporting room, oil suction chamber at this time
Interface flows back into oil suction chamber, and another part pressure oil is then flowed out from the oil discharge outlet of pressure limiting valve, to reduce output pressure.
Control system provided by the invention passes through the united application of pressure limiting valve and switch electromagnetic valve, makes fixed displacement lubricating oil pump
It is able to achieve two-stage variable discharge capacity, and controls simple, in time, the system is by the aperture of regulation pressure-limiting valve, to control machine oil for response
The flow of output is pumped, to achieve the effect that reduce power.Control system of the invention had both taken full advantage of fixed displacement lubricating oil pump
The advantages of middle and slow speed of revolution volumetric efficiency height, stable structure, at low cost, good reliability, and assign fixed displacement lubricating oil pump " second level becomes
The ability of row ".Because fixed displacement lubricating oil pump has part few, stable structure for vane-type variable flow machine oil pump,
The advantages that cost is relatively low, good reliability, and volumetric efficiency of the constant displacement pump in middle low speed is also higher than vane pump, it is low in identical
Under fast operating condition, the discharge capacity of constant displacement pump can be designed smaller, so as to the torque in low speed section in reducing.
