摘要： This invention provides an improved variable cam phaser for an automobile engine equipped with a controller capable of enabling execution of a given phase angle varying command in a shortened response time. The variable cam phaser has two control rotors which are arranged coaxial with a camshaft and rotatable relative to each other under the influence of two electromagnetic actuators and driven by the crankshaft of the engine. The variable cam phaser also has a relative phase angle varying mechanism for varying the relative phase angle of the camshaft relative to the crankshaft. When the two electromagnetic actuators are simultaneously energized, the two control rotors are held mutually unrotatable. However, when the braking torque of one actuator is reduced, the control rotor associated with that actuator is rotated relative to the other control rotor to immediately start the execution of the command.

摘要： [Problems]To provide a variable phase controller for an engine which assures easy manufacturing at low cost, reduces operating sound, and includes a relative rotational motion mechanism enabling quick change of a phase angle between a cam shaft and a crank shaft.[Means for Solving Problems]A variable phase controller for an engine controls the rotational motion of a first control rotor for changing the relative phase angle between a crank shaft and a cam shaft to either a phase-lead angle side or a phase-lag angle side in accordance with the direction of such control. The variable phase controller has a first braking means for rotating the first control rotor to one side, and a second braking means for braking a second control rotor and rotating the first control rotor in the direction opposite to the rotation caused by the first braking means via a second intermediate rotor (or cam guide plate) displaced by the force applied by a movable element (or rotating eccentric circular cam) displaced in guide grooves by braking of the second control rotor, thereby controlling the rotational motion of the first control rotor.

摘要： OBJECTTo provide a simpler, axially shorter, and easy-to-manufacture phase varying apparatus for an automobile engine, utilizes a four-link mechanism consisting of multiple circular members. MEANS FOR ACHIEVING THE OBJECTAn inventive phase varying apparatus has: a camshaft; drive rotor driven by the crankshaft; a first and a second torque means for rotating a first and a second control rotors, all aligned coaxially and rotatable relative to each other; and a phase angle varying mechanism operably coupled to the first and second torque means, so as to varying the relative phase angle between the camshaft and the crankshaft. The phase angle varying mechanism comprises: a circular eccentric cam integral with the camshaft; a first and a second link each having a shape of a substantially cylindrical form; and a quasi-radial guide mechanism and displacement forcing means collaborating with each other for displacing either one of the first and second links in a quasi-radial direction of the rotor.

摘要： [OBJECT] After having determined a phase angle, the phase angle is maintained as the determined one without consuming electric power. [ACHIEVING MEANS] An intermediate member 14 is movably disposed on the outer periphery of an inner cylinder part 12 that is relatively rotatably disposed with respect to an outer cylinder part 10 to which a driving force of a crankshaft is transmitted and that is connected to a camshaft. In a process in which the intermediate member 14 moves in the axial direction when a solenoid 74 or a solenoid 76 is energized, balls 46 and 48 move in mutually opposite directions in response to a displacement in the axial direction caused by the movement of the intermediate member 14, and the phase between the outer cylinder part 10 and the camshaft 2 is variably adjusted. After the intermediate member 14 is set at an advance position or a retard position when the solenoids 74 and 76 are deenergized, the balls 46 and 48 stop moving for the input of torque from the outer cylinder part 10 or from the camshaft 2, anda self-locking state is reached.
