- Patent Document 1 Japanese Patent Application "Kokai" No. 10-220207
- Pulsating displacements due to such torque variations described above will occur conspicuously in particular when the pressure of the fluid fed from the pump is low. And, this phenomenon occurs also in the course of switchover of the phase of the cam shaft relative to the crank shaft to a target phase on the retarded angle side from the advanced angle side.
- a pressure drop due to the pulsating pressure may lower a lock released state maintaining pressure of the lock mechanism, as a result of which the locking mechanism may be brought into its locking state inadvertently.
- a lock pin provided as a restricting member for the locking mechanism pivots about the outer periphery of a receiving hole while this lock pin is being accommodated within a retracting hole.
- the object of the present invention is to provide a valve timing control apparatus capable of avoiding inadvertent realization of a locked state by effectively preventing pulsating pressure of fluid generated in association with torque variation of a cam shaft from having any effect on a fluid passageway for lock releasing, thereby to restrict occurrence of inadvertent realization of the locked state during driving of the internal combustion engine.
- the apparatus comprises:
- a check valve that inhibits communication of the fluid from the first switching valve to the second switching valve and allows communication of the fluid from the second switching valve to the first switching valve. Therefore, it is possible to prevent pulsating pressure that occurs in association with torque variation in the rotational shaft from being transmitted from the first switching valve to the second switching valve. Hence, stable fluid free from the influence of the pulsating pressure can be fed from the second switching valve to the third fluid passageway. As a result, the locking mechanism can effectively maintain its lock-released state by this stable fluid pressure and the inadvertent locking of the mechanism can be avoided.
- the fluid fed from said pump can be fed to said first switching valve with bypassing said second switching valve and can be fed to said second switching valve with bypassing said first switching valve.
- passage resistance of the first switching valve and the passage resistance of the second switching valve do not affect each other. Hence, controlling operation of rotational phase and controlling operations of the locking mechanism can be effected more speedily.
- the fluid fed from said pump can be fed to said first switching valve through said check valve and can be fed to said second switching valve with bypassing said check valve.
- the check valve is interposed between the pump and the first switching valve, it is possible to prevent pulsating pressure of the fluid occurring due to torque variation in the rotational shaft from being transmitted to the pump. Therefore, the pulsating pressure will not affect the second switching valve via the pump. As a result, the locking mechanism can effectively maintain its lock-released state by this even more stable fluid pressure.
- the apparatus further comprises:
- passage resistance of the first switching valve and the passage resistance of the second switching valve do not affect each other.
- controlling operation of rotational phase and controlling operations of the locking mechanism can be effected more speedily.
- the pulsating pressure does not affect the second switching valve via the pump.
- the locking mechanism can effectively maintain its lock-released state by this even more stable fluid pressure.
- an aperture area of said check valve when the fluid is being fed from said pump to said first switching valve is greater than a passageway aperture area of said first connecting passageway.
- the passageway aperture area of said first connecting passageway is greater than the passageway aperture area of said second connecting passageway.

- the pilot passageway 13 is connected to a connection port 111 of a second switching valve 110 via an annular passageway 95 and a connecting passageway 96 also provided on the outer peripheral side of the supported portion of the cam shaft 10.
- the first switching valve 100 is controlled for its switching operations by a controller (not shown). Under the condition shown in Fig. 1 and Fig. 2 wherein the valve 100 is switched to an angle advanced position (energized state), a supply port 103 connected to an oil pump 120 via a check valve 140 is connected and communicated to the connection port 101 and also the connection port 102 is connected and communicated to an exhaust port 104 connected to an oil pan 130.

Further, under the condition shown in Fig. 2 wherein the valve 110 is switched to the exhausting position (non-energized state), the connection port 111 is connected and communicated to the exhaust port 113 whereas the supply port 114 is blocked. Therefore, under this supplying position condition, oil is supplied to the pilot passageway 13 and under the exhausting position condition, oil is discharged through the pilot passageway 13 to the oil pan 130.
- the inner rotor 30 is fixedly and integrally attached to the cam shaft 10 by the bolt 16 and includes vane grooves 31 for allowing attachment of the four respective vanes 50 along the radial direction.

- the receiving groove 32 is a groove for receiving a head of the lock plate 60a, 60b by a predetermined engagement amount under the condition shown in Fig. 2 , i.e. the condition wherein the relative phases of the driven rotational body such as the cam shaft 10, the inner rotor 30, etc. and the driving rotational body such as the outer rotor 40, the timing sprocket 70, etc. come into synchronization or registry with each other at a predetermined phase (an intermediate phase between the most advanced angle phase and the most retarded angle phase suitable for startup of the internal combustion engine).
- a predetermined phase an intermediate phase between the most advanced angle phase and the most retarded angle phase suitable for startup of the internal combustion engine.
- the outer rotor 40 is assembled to the outer periphery of the inner rotor 30 to be rotatable relative thereto over a predetermined range. And, on opposed sides of the outer rotor 40, a front plate 41 and a rear plate 42 are integrally fastened by means of a bolt 43. Further, in the outer rotor 40, there are formed, by the inner rotor 30, a plurality of operational chambers R0 each of which accommodates the vane 50 corresponding thereto and which is divided into an advanced angle chamber R1 and a retarded angle chamber R2.
- retracting grooves 46a, 46b for accommodating the lock plates 60a, 60b and springs 61a, 61b for urging these plates 60a, 60b toward the inner rotor 30.
- the lock plates 60a, 60b are engaged in the retracting grooves 46a, 46b to be movable along the radial direction of the outer rotor 40 and are urged by the springs 61a, 61b toward the inner rotor 30.
- the springs 61a, 61b are compression springs interposed between the lock plates 60a, 60b and retainers 62a, 62b and these retainers 62a, 62b are fixedly assembled to the outer rotor 40.
- the engine is started up under the condition shown in Fig. 2 , that is, the condition wherein the heads of the lock plates 60a, 60b are engaged and locked within the receiving grooves 32 at a predetermined phase suitable for startup of the internal combustion engine.
- the oil pump 120 is driven to start feeding of an amount of oil.
- the oil discharged from the oil pump 120 is supplied via the check valve 140 from the supply port 103 of the first switching valve 100 through the connection port 101, the connecting passageway 92, the annular passageway 91, the advanced angle passageway 11, the connecting passageway 34 to the advanced angle chamber R1.
- an amount of oil fed from the oil pump 120 to the second switching valve 110 is not supplied to the pilot passageway 13 because the supply port 114 of the second switching valve 110 is currently blocked, so a locking state is maintained.
- the first switching valve 100 is energized by a signal from the controller (not shown), as shown in Fig. 5 , the amount of oil discharged from the oil pump 120 is supplied via the check valve 140 from the supply port 103 of the first switching valve 100 through the connection port 102, the connecting passageway 94, the annular passageway 93, the retarded angle passageway 12 and the connecting passageway 37 to the retarded angle chamber R2.
- an amount of oil is discharged from the advanced angle chamber R1 through the advanced angle passageway 11, the switching valve 100, etc. into the oil pan 130.
- the driven rotational body including the cam shaft 10, the inner rotor 30 and the vanes 50, etc.

- the check valve 140 which allows communication of oil to the first switching valve 100 and inhibits (checks) communication of oil to the oil pump 120.
- the second switching valve 110 for controlling feeding/discharging of oil to/from the pilot passageway 13 is connected to the oil pump 120 via the second connecting passageway 84 branched from a branching point 83 of the first connecting passageway 82 connecting between the oil pump 120 and the check valve 140.
- the check valve 140 pulsating pressure of oil that occurs due to torque variation in the cam shaft 10 can be prevented from being transmitted from the first switching valve 100 to the oil pump 120.
- the second switching valve 110 is supplied with oil through the second connecting passageway 84 branched from the first connecting passageway 82 connecting between the oil pump 120 and the check valve 140, the second switching valve 110 is free from any effect of the pulsating pressure of oil that occurs due to torque variation in the cam shaft 10. So that, the oil can be supplied in a stable manner from this second switching valve 110 to the pilot passageway 13. As a result, the stable oil can be supplied to the receiving groove 32, so that the condition of the lock plates 60a, 60b being accommodated within the retracting grooves 46a, 46b can be maintained, thereby to prevent occurrence of inadvertent locking.
- the aperture area of the check valve 140 be greater than the passageway aperture area of the first connecting passageway 82. Further, for preferential supply of oil to the operational chamber R0 during the advanced/retarded angle control operations, it is preferred that the passageway aperture area of the first connecting passageway 82 be greater than the passageway aperture area of the second connecting passageway 84.
- the predetermined phase being an intermediate phase between the most advanced angle phase and the most retarded angle phase suitable for startup of the internal combustion engine.
- the invention is not limited thereto. Instead, the "predetermined phase” can be the most retarded angle phase or the most advanced angle phase, as a matter of course.
- the present invention is applicable to a valve timing control apparatus used for controlling opening/closing timing of an exhaust valve or an intake value in a valving device of an internal combustion engine.
