Abstract
The invention relates to a hydraulic speed regulator which comprises a camshaft, a cam, an oil bucket, an oil pipe, a main engine oil pump and a manual control throttle, and is characterized by further comprising a speed-regulation oil pump, a high-pressure oil pipe, a speed-regulation hydraulic cylinder, a piston, a spring, a piston handle and an oil regulating valve. When oil which is sent into the speed-regulation hydraulic cylinder is more than that flowing out of the speed-regulation hydraulic cylinder, the piston moves right to reduce the oil supply quantity each time of the main engine oil pump; when the oil which is sent into the speed-regulation hydraulic cylinder is equivalent to that flowing out of the speed-regulation hydraulic cylinder, the piston does not move and the oil supply quantity each time of the main engine oil pump is unchanged; and when the oil which is sent into the speed-regulation hydraulic cylinder is less than that flowing out of the speed-regulation hydraulic cylinder, the piston moves left to increase the oil supply quantity each time of the main engine oil pump. The hydraulic speed regulator has the advantages of being simple, being small in volume, being light in deadweight and being beneficial to the improvement on an internal combustion engine.
Description
One, technical field
Hydrodynamic governor of the present invention belongs to plant equipment.
Two, background technology
Traditional speed regulator can only remove throttle by the rotating speed responding to internal combustion engine, and its deadweight is heavier, volume is also larger.
Three, summary of the invention
For the defect that above-mentioned technology exists, I devises a kind of speed regulator utilizing fluid pressure to regulate and control throttle, this speed regulator is very little from heavy and light, volume, and the past counter-movement number of times by responding to internal combustion engine removes throttle, also by responding to the fuel feeding number of times regulation and control throttle of camshaft.
The technical scheme that the present invention takes is as follows:
This hydrodynamic governor includes: camshaft, cam, oil drum, main lubricating oil pump, manual control accelerograph, is characterized in that:
1, regulation oil pump, high-pressure oil pipe, speed governing fluid cylinder, piston, spring, piston handle, oil pipe, oil regulating valve;
2, oil regulating valve is the speed that oil in adjustment speed governing fluid cylinder flows back to oil drum and goes, and the pressure that speed governing fluid cylinder, piston, piston handle bear is little, and available aluminium does.
When the engine operates, the cam of camshaft constantly makes main lubricating oil pump and regulation oil pump fuel feeding, regulation oil pump the oil of confession send into speed governing fluid cylinder through high-pressure oil pipe, the oil in speed governing fluid cylinder flows into oil drum, when engine speed is too high through oil pipe again, within the unit interval, the fuel feeding of governor impeller often, sends into the oil of speed governing fluid cylinder just more than the oil flowed out in speed governing fluid cylinder, moves right so just promote piston, the each fuel delivery of main lubricating oil pump is reduced, and engine speed just reduces; When engine speed is rated speed, the oil sending into speed governing fluid cylinder just equals the oil flowed out from speed governing fluid cylinder, piston is motionless, main frame just at the uniform velocity rotates, when engine speed is lower than rated speed, the oil sending into speed governing fluid cylinder is just less than the oil flowed out from speed governing fluid cylinder, so piston is just moved to the left, the each fuel delivery of main lubricating oil pump is increased, and engine speed is just accelerated.
The advantage of hydrodynamic governor:
1, simple and easy, with main lubricating oil pump common cam shaft, be conducive to reducing the deadweight of main body sum.
2, the improvement of internal combustion engine is conducive to: this speed regulator is mainly used in connecting internal combustion engine of living, (internal combustion engine of living also will applied for a patent in the recent period).
