Description
Technical field
The present invention relates to the supply system technical field, relate in particular to a kind of engine lubricating oil oil feeding system.
Background technique
General motor supplying lubricating oil adopts motor pump to carry out supplying lubricating oil more, motor pump exists and to need the motor driving operation of oil pump, and complex structure, cost height, fluctuation of service, sealability is to be improved, working life is short, maintenance cost is high shortcoming.
Summary of the invention
The object of the invention is to for the problems referred to above deficiency, a kind of engine lubricating oil oil feeding system be provided, have good seal performance, constant oil supply, stable, long service life, simple in structure, save the energy, need not the advantage of extra motor.
In order to achieve the above object, the present invention is by the following technical solutions:
The engine lubricating oil oil feeding system, be provided with oil pump housing, described oil pump housing one end is provided with the oil pump enclosing cover, and the other end is provided with the oil pump inner cap, be provided with one rounded, inside in the middle of the described oil pump housing and eccentric wheel be installed and cooperate the oil pump inner cap and the oil pump enclosing cover forms the perforation structure of oil pocket, this perforation structure stretch out an oil inlet hole and an oil outlet; Be provided with the pressure spring type sealer of being close to the eccentric wheel periphery between described oil inlet hole and the oil outlet.
Described pressure spring type sealer by the sealer mounting hole of being located between oil pump housing oil inlet hole and the oil outlet and connect with oil pocket, be located in the sealer mounting hole and the link block that fits tightly with eccentric wheel and the stage clip of being located at the link block the other end form.
Described eccentric wheel center is provided with spindle hole.
Described oil pump enclosing cover exterior periphery is provided with a circular groove that is ring, and this circular groove cooperates with the oil pump housing inwall and forms a seal ring die cavity is installed.
Described seal ring is installed in the die cavity and is provided with a seal ring.
Described seal ring is O-ring seals.
Further, described oil inlet hole and oil pocket connect, and described oil outlet and oil pocket connect.
Further, described spindle hole is installed on the main shaft, and this main shaft provides power by in-engine swash plate mechanism.Described main shaft and spindle hole are undertaken spacing by position limit pin.
When eccentric wheel rotates to when not blocking oil inlet hole, oil inlet hole and oil pocket connect, and lubricant oil enters oil pocket inside by oil inlet hole, and under the effect of eccentric wheel rotary thrust, the lubricant oil in the oil pocket flows towards the oil outlet direction.When eccentric wheel rotates to when not blocking oil outlet, oil outlet and oil pocket connect, and under eccentric wheel rotary thrust active force, the lubricant oil in the oil pocket flows out through oil outlet.
The present invention adopts said structure, have good seal performance, constant oil supply, stable, long service life, simple in structure, save the energy, need not the advantage of extra motor.
