摘要： PROBLEM TO BE SOLVED: To provide a valve timing variable device with a restriction pin for restricting a valve timing changeable range projected in an early stage.
SOLUTION: This valve timing variable device is so configured that when the restriction pin is projected from a storage hole, the cross-sectional area of an oil passage for discharging hydraulic fluid pressing the restriction pin to the storage hole is increased. By such a structure, time required for setting pressing force by the hydraulic fluid weaker than urging force for urging the restriction pin in a projecting direction is shortened. Therefore, the restriction pin is projected in an early stage.

摘要： PROBLEM TO BE SOLVED: To provide a rotational-linear motion converting mechanism can restrain damaging of a thread of a female screw formed in a tapered part of a ring shaft.
SOLUTION: In this rotational-linear motion converting mechanism, a boundary Kr between a screw part 21A and a tapered part 21B in the ring shaft 2, is positioned near an end part (a tapered part 41B) of a shaft 4 by a predetermined quantity X, to a boundary Kp between a screw part 41A and the tapered part 41B in the planetary shaft 4. Thus, even if displacement is caused in the axial direction of the planetary shaft 4 due to a backlash, the displacement of the boundary Kp near the tapered part 21B to the boundary Kr in response to its displacement is restrained. Thus, meshing of a thread of a male screw 44 formed in a screw part 41A of the planetary shaft 4 with a thread of an incomplete shape of a female screw 24 formed in the tapered part 21B of the ring shaft 2, can be restrained.

摘要： PROBLEM TO BE SOLVED: To provide a planetary differential screw type rotation linear motion converting mechanism capable of suppressing increase in shift amount of a sun shaft even when the number of planetary shafts is reduced, and an actuator.
SOLUTION: Between an annular shaft 4 and the sun shaft 6 of the planetary differential screw type rotation linear motion converting mechanism 2, non-threaded planetary shafts 10 are arranged together with the arrangement of the planetary shafts 8 within the arrangement. The non-threaded planetary shaft 10 is formed of only a planetary gear, reducing manufacturing cost. Even when the number of the planetary shafts 8 requiring high manufacturing cost is reduced from 9 to 3, the non-threaded planetary shafts 10 can sufficiently suppress increase in the shift amount of the sun shaft 6. Thus, the actuator to which the planetary differential screw type rotation linear motion converting mechanism 2 is incorporated can highly accurately drive a variable valve train, achieve adjustment of valve working angle of an intake valve which is not disadvantageous to energy saving of an internal combustion engine, and prevent deterioration of fuel economy of the internal combustion engine.

摘要： PROBLEM TO BE SOLVED: To provide an electromagnetic drive valve in which the mountability can be improved by preventing an armature stem from becoming longer in the axial direction owing to the incorporation of a lift sensor.
SOLUTION: The armature stem 21 fixed with an armature 33 is coaxially arranged in a valve 11 functioning as a suction valve or an exhaust valve. An electromagnetic actuator 35 for closing drive is arranged around the armature stem 21, and the electromagnetic force actuates the armature 33 to open and close the valve 11 by displacing the armature stem 21 axially. The lift sensor 38 detects an amount of axial displacement in the armature stem 21 owing to the axial relative movement of a sensor coil 42 and a sensor core 46 accompanied by the displacement of the armature stem 21. In the armature stem 21, a recess 39 is installed in an opening at the upper end, and at least a part of each sensor coil 42 and sensor core 46 is arranged in the recess 39 respectively.
