Abstract: A valve timing adjusting apparatus for an internal combustion engine having a bearing includes a camshaft, a housing, a vane rotor, a control valve, and a fastening member. The fastening member is mounted on an axial end portion of the camshaft on a side of the vane rotor opposite from the bearing. The vane rotor is coaxially fastened to the camshaft between the fastening member and a step portion, which is provided to the camshaft on a side of the bearing. A sleeve of the control valve is coaxially received in an axial hole of the camshaft, which opens at an end surface of the end portion of the camshaft. Each of the advance output port and the retard output port is communicated with a corresponding one of the advance chamber and the retard chamber through the camshaft.

Abstract: One of retard passages, which supplies working fluid to one of retard chambers, is a dedicated passage. The other remaining retard passages, which supply the working fluid to the other remaining retard chambers, are branch passages, which are branched from a retard passage that serves as a supply passage. With this construction, a flow quantity of working fluid per unit time supplied from the one of retard passages to the one of retard chambers becomes larger than a flow quantity of working fluid per unit time supplied from the other remaining retard passages to the other remaining retard chambers. Thus, the one of retard chambers can be filled with the working fluid earlier than the other remaining retard chambers.

Abstract: A shoe housing 3 is connected to and rotatable together with an input shaft. A vane rotor 9 is connected to an output shaft and accommodated in shoe housing 3 so as to cause a rotation within a predetermined angle with respect to shoe housing 3. Vane rotor 9 and shoe housing 3 cooperatively define hydraulic chambers 10, 11, 12 and 13 whose volumes are variable in accordance with a rotational position of vane rotor 9 with respect to shoe housing 3. A locking member 7 is accommodated in vane rotor 9 and shiftable in a direction parallel to a rotational axis common to shoe housing 3 and vane rotor 9. And, an engaging bore 20, formed on a front plate 4 secured to shoe housing 3, receives locking member 7 through a tapered surface. With this arrangement, it becomes possible to provide a control apparatus for varying a rotational or angular phase between the input and output shafts, while adequately maintaining the durability of the apparatus with a simple configuration easy to manufacture and suitable for downsizing without causing hammering noises or increasing operational resistances.

Abstract: In a vane-type rotational phase adjusting apparatus used for adjusting opening/closing timings of an intake valve or an exhaust valve of an engine, a housing unit driven by a driving shaft has a fan-shaped accommodating chamber between adjacent two of a plurality of shoes arranged circumferentially. A vane unit for driving a driven shaft is disposed in the housing unit with its vanes being disposed in the corresponding one of the accommodating chamber so that the rotational phase of the driven shaft is adjusted by the pressure of fluid in the accommodating chamber. Recesses are formed as fluid reservoirs in a cross-sectionally half circle shape on the circumferential end walls of the shoes to hold the operating fluid therein when the housing unit and the vane unit are at rest because of engine stop.

The end face of the rotary member is formed therein with an annular recess and has a reference position information projection on the radially inner peripheral wall of the recess and a plurality of angular position information projections on the radially outer peripheral wall of the recess. The rotary member is covered with a detector housing mounted on the engine block and having an outer end wall supporting sensors faced to the circular paths of circumferential movements of the projections on the rotary member. The detector housing end wall has central opening with a bearing mounted therein to receive the outer end portion of the cam shaft and position the detector housing relative to the cam shaft whereby the sensors are precisely positioned relative to the circular paths of the movements of the projections. The cam shaft terminates in an outer end extremity on which a distributor rotor is mounted and covered with a distributor cap mounted on the detector housing.
