Abstract: An engine rotational position detector and distributor assembly has a crank-driven rotary member mounted on an end portion of a cam shaft extending outwardly from engine block. 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.

Abstract: An assist spring is fixed at its one end to a vane rotor and at its other end to a spring hook provided at an outside of a housing 18. A signal plate is fixed to the vane rotor on a side of the spring hook. A cam angle sensor is provided at an outer peripheral side of the signal plate for detecting a rotational angle of the signal plate. The assist spring and the spring hook are arranged in an area, which is inside of an outer periphery of the signal plate in a radial direction, so that the cam angle sensor may not misidentify the assist spring and the spring hook and thereby exactly detects the rotational angle of the signal plate.

Abstract: A first-side check valve prevents a hydraulic fluid from being discharged out of a retard chamber, and a second-side check valve prevents the hydraulic fluid from being discharged out of an advance chamber. A first-side control valve opens or closes a first-side discharge passage by a pilot pressure received through a retard pilot passage. A second-side control valve opens or closes a second-side discharge passage by the pilot pressure received through an advance pilot passage. Another check valve is disposed in a supply passage between a phase switch valve and a branch point, at which a supply passage is branched.

Abstract: A valve timing adjusting apparatus has a housing and a vane rotor to form multiple fluid chambers, and a relative position of the vane rotor to the housing is adjusted by the fluid pressure supplied into the fluid chambers. A check valve is provided in a branched passage portion, so that working fluid may not be pushed out from an advancing fluid chamber to a low pressure side, even when the working fluid in the advancing fluid chamber is temporally compressed to increase its fluid pressure due to a torque change applied from a cam shaft to the vane rotor.

Abstract: A base material of a peripheral wall and a vane rotor is formed by extrusion molding an aluminum alloy and cutting an extrusion molded article to the desired length. Further, the extrusion molded article can be molded with high accuracy by extracting the aluminum alloy after extrusion. Preferably, 6000 system of Al—Mg—Si is used as an aluminum alloy. The cutting process and polishing process are applied to the roughly molded base material to form the peripheral wall and the vane rotor. By varying the length to be cut, the volume of each retard hydraulic chamber and each advance hydraulic chamber are adjusted. When the volume of the hydraulic chambers are adjusted, the torque for relatively rotating and driving the vane rotor with respect to the housing member can be changed even pressure of working oil is the same.

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 angles 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.
