    摘要: Disclosed is 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 used for lock releasing. The apparatus includes a first fluid passageway for feeding/discharging fluid to/from an advanced angle chamber, a second fluid passageway for feeding/discharging fluid to/from a retarded angle chamber, a third fluid passageway for feeding/discharging fluid to/from a locking mechanism capable of locking relative rotation between an inner rotor and an outer rotor, a first switching valve for controlling the feeding/discharging of the fluid to/from the first fluid passageway and the second fluid passageway, a second switching valve for controlling the feeding/discharging of the fluid to/from the third fluid passageway, a pump for feeding fluid to the first switching valve and the second switching valve, and a check valve for inhibiting communication of the fluid from the first switching valve to the second switching valve and allowing communication of the fluid from the second switching valve to the first switching valve.

The device (1) also comprises at least one rotation angle limiting device (24 that, in an unlock state, does not limit the phase position of the output element (3) relative to the input element (2) but, in a locked state, limits it to a defined angular range or to a defined angle. The rotation angle limiting device (24) is transferred from the locked to the unlocked state by supplying pressure medium. A control line (19) is provided for supplying and withdrawing pressure medium to or from the rotation angle limiting devices (24), the control line (19) not communicating with the pressure medium supply device (32). A control valve (38) controls the supply and withdrawal of pressure medium to and from the control line (19). The control valve (38) comprises a hydraulic actuating mechanism (39) that is subjected to the action of pressure medium by the pressure medium supply device (32).

    摘要: A variable valve timing device is provided having a speed reduction mechanism that is simple in structure and which can keep the relative rotation between the camshaft and the sprocket within a predetermined angular range even if the speed reduction mechanism malfunctions. A camshaft (1) and a sprocket (2) are coaxially provided so as to be rotatable relative to each other. A speed reduction mechanism (5) is mounted in a housing (7) which is rotationally fixed to the sprocket (2). The speed reduction mechanism (5) includes an intermediate shaft (10) having a retainer portion (10b) retaining a plurality of rollers (9) disposed between the outer periphery of an eccentric shaft portion (6) of an output shaft (4) of an electric motor (3) and an internal gear (8) fixed in position in the housing (7). The intermediate shaft (10) has a stopper pin (17) provided on the intermediate shaft (10) engaged in an engaging recess (18) formed in the sprocket (2) so as to be movable within the range of the circumferential length of the recess (18). When the output shaft (4) of the electric motor (3) rotates, the rollers (9) are pressed against the teeth of the internal gear (8) by the eccentric shaft portion (6) and revolve around the output shaft (4). The revolution of the rollers (9) is transmitted to the camshaft (1) through the intermediate shaft (10), thus changing the angular position of the camshaft (1) relative to the sprocket. If the speed reduction mechanism (5) malfunctions, the stopper pin (17) engages the engaging recess (18), thus restricting the relative rotation between the intermediate shaft (10) and the stopper pin (17) within a predetermined angular range.
