The secondary structure connected with clearance portion 21, spool oil groove B9, valve pocket oilhole B7, oil pocket B, described oil pocket A
It is set to successively with valve pocket oilhole A6, valve body interstitial hole 17, outer oil sump oilhole 18, oil return opening 4, fuel tank even
Logical structure.So machine oil from oil-in enter oil pocket B, the machine oil in oil pocket A then from oil pocket A through fuel-displaced
Mouthful, it flow back in fuel tank, after oil pocket A and oil pocket B inner engine oil amount change, it is achieved continuous variable valve is just
Time system the rotor rotation to a direction, it is achieved the change of engine valve timing adjusts.
When described valve body 2 is positioned at valve pocket pars intermedia 27 position of valve pocket cavity 11, described in put valve can
Realize the oil circuit (as shown in Figure 3) of the second state.Due to the shift position of spool, described band
The band A28 of 26 is set to seal the structure that can seal valve pocket oilhole A6, the band of band 26
B29 is configured to seal the structure of valve pocket oilhole B7.Under the most such situation, in oil pocket A and oil pocket B
Oil level will not change, and rotor cannot realize the rotation of the rotor of continuous variable valve timing system, starts
The angle of machine valve timing will not change and adjust, and meets the demand of continuous variable timing system.
When described valve body 2 is positioned at 14 position, valve pocket right part of valve pocket cavity 11, described in put valve can
Realize the oil circuit (as shown in Figure 4) of the third state.Due to the shift position of spool, described oil-in
3 be set to successively with clearance portion 17, spool oilhole B9, spool outer oil sump 15, valve body oilhole A8, valve pocket oil
Hole A6, oil pocket A connection structure, described oil pocket B be set to successively with valve pocket oilhole B7, valve body in the middle of
Hole 17, outer oil sump oilhole 18, the structure of oil return opening 4 connection.Such structure arrange, when with high-pressure oil duct
The machine oil of connection enters oil pocket A from oil-in, the machine oil in oil pocket B then from oil pocket B through oil-out, stream
Return in fuel tank, after oil pocket B and oil pocket A inner engine oil amount change, it is achieved continuous variable valve timing system
Rotor to the rotation contrary with the oil circuit of the first state, it is achieved engine valve timing is round about
Change adjusts；Meet the demand of continuous variable timing system.
The control of valve kinestate in valve pocket cavity is put, it is possible to realize three kinds of state oil circuits by centering, three
Cooperation between the oil circuit of the state of kind, can be achieved with continuous variable valve timing system rotor rotation direction and turns
The control of dynamic angle, it is achieved continuous variable valve timing system works the most on the engine.
The present invention puts valve arrangement in continuous variable valve timing system, when controlling spool at valve pocket cavity
When being inside in diverse location, it is possible to realize the oil circuit of different conditions, the oil circuit cooperating of different conditions, with regard to energy
Enough realizations are to continuous variable valve timing system rotor rotation direction and the control of rotational angle, it is achieved continuous variable
Valve timing system works the most on the engine.Of the present invention for continuous variable valve timing
System puts valve arrangement, simple in construction, dependable performance, with low cost, it is possible to put in realizing conveniently and efficiently
Valve internal oil passages changes, it is achieved different oil circuit trends, machine oil is by different oil circuits, it is achieved with oil pocket A or oil pocket
The connection of B, meets VVT centering and puts valve internal oil passages change demand.
Above in conjunction with accompanying drawing, the present invention is carried out exemplary description, it is clear that concrete implementation of the present invention is not subject to
The restriction of aforesaid way, if the various improvement that the method design that have employed the present invention is carried out with technical scheme, or
The most improved design by the present invention and technical scheme directly apply to other occasions, all in the protection of the present invention
In the range of.
