Claims
- 1. A valve timing control device associated with an internal combustion engine comprising:a rotational member which rotates together with a cam shaft of said internal combustion engine during running thereof; a rotation transmission member mounted on said rotational member so as to rotate relative thereto and rotating together with a crank shaft of said internal combustion engine; a phase adjusting mechanism which adjusts a rotational phase of said rotational member relative to a rotational phase of said rotation transmission member based on a magnitude of a fluid pressure; a regulating valve which controls the magnitude of the fluid pressure supplied to said phase adjusting mechanism; an electromagnetic mechanism mounted to said internal combustion engine and having a pushing member, said pushing member being moved in the axial direction of the cam shaft upon activation of said electromagnetic mechanism, said regulating valve being moved upon engagement with said pushing member; and an adjusting member interposed between said pushing member and said regulating valve for adjusting the amount of the axial movement of said regulating valve.
- 2. The valve timing control device associated with an internal combustion engine according to claim 1, wherein the adjusting member is shaped as a substantially cylindrical cup.
- 3. The valve timing control device associated with an internal combustion engine according to claim 1, wherein the rotational transmission member is driven by a chain.
- 4. The valve timing control device associated with an internal combustion engine according to claim 1, wherein the adjusting member is further for adjusting an initial position of the pushing member and a clearance between the pushing member and the regulating valve.
- 5. The valve timing control device associated with an internal combustion engine according to claim 1 further comprising a connecting member accommodating therein the regulating valve, the connecting member being operatively connected to fasten the rotational member to the cam shaft.
- 6. The valve timing control device associated with an internal combustion engine according to claim 1, wherein the regulating valve is urgingly biased against the adjusting member by a spring.
- 7. The valve timing control device associated with an internal combustion engine according to claim 5, wherein the regulating valve is operatively positioned at a center portion of the connection member.
- 8. The valve timing control device associated with an internal combustion engine according to claim 1, wherein the pushing member, the regulating valve, and the adjusting member are lubricated.
- 9. The valve timing control device associated with an internal combustion engine according to claim 1, wherein the regulating valve includes a projection tip abutting the adjusting member, and the projection tip has a spherical outer surface.
- 10. A valve timing control device associated with an internal combustion engine comprising:a rotational member rotating together with a cam shaft of said internal combustion engine during running thereof; a rotation transmission member mounted on said rotational member so as to rotate relative thereto and rotating together with a crank shaft of said internal combustion engine; a phase adjusting means for adjusting a rotational phase of said rotational member relative to a rotational phase of said rotation transmission member based on a magnitude of a fluid pressure; a regulating means for controlling the magnitude of the fluid pressure supplied to said phase adjusting means; an electromagnetic means mounted to said internal combustion engine, for selectively engaging and thereby axially moving the regulating means along an axis of the cam shaft, the electromagnetic means having a pushing means for engagingly contacting with the regulating means in axially moving the regulating means; and an adjusting means interposed between said pushing means and said regulating means, for adjusting the amount of the axial movement of said regulating means.
- 11. The valve timing control device associated with an internal combustion engine according to claim 10, wherein the adjusting means includes a substantially cylindrical cup operatively connected to an end portion of the pushing means.
- 12. The valve timing control device associated with an internal combustion engine according to claim 10, wherein the rotational transmission member is driven by a chain.
- 13. The valve timing control device associated with an internal combustion engine according to claim 10, wherein the adjusting means is further for adjusting an initial position of the pushing means and a clearance between the pushing means and the regulating means.
- 14. The valve timing control device associated with an internal combustion engine according to claim 10 further comprising a connecting means formed to accommodate therein the regulating valve and for fastening the rotational member to the cam shaft.
- 15. The valve timing control device associated with an internal combustion engine according to claim 10, wherein the regulating means includes a valve element urgingly biased against the adjusting means by a spring.
- 16. The valve timing control device associated with an internal combustion engine according to claim 14, wherein the regulating means includes a valve element accommodated in a center portion of the connection means.
- 17. The valve timing control device associated with an internal combustion engine according to claim 10, wherein the regulating means includes a valve element having a projection tip for contacting the adjusting means, and the projection tip has a spherical outer surface.
