摘要： A process for the manufacture of a camshaft comprises the steps a) providing a segment with a hole wherein the shape of the hole is adapted to fit onto the cross section of the shaft when a force is applied radially to the segment, b) with the same force as in step a) applied, inserting the camshaft axially into the hole in the segment, and when the segment is placed in the desired position on the camshaft; c) releasing the force applied to the segment so that the segment changes shape and comes into contact with the camshaft. Advantages include that the camshaft can be made lightweight, with less difficulties and at a lower cost.

The decompression device (1) has a shaft (10) located axially within the camshaft (2), and rotatable relative to the camshaft (2) to extend or retract a first and a second lifter (12, 13) radially. The first and second lifters (12, 13) are respectively provided inwardly of lobe faces of the first and second lobes (14, 15) on the camshaft (2) in a radial direction of the camshaft (2) such that the first lifter and the second lifter (12, 13) can extend outwardly or retract inwardly in the radial direction from the lobe faces. The shaft (10) has first and second eccentric portions (10A, 10B) located in transverse slots (12B, 13B) in the first and second lifters (12, 13) to extend or retract the first and second lifters (12, 13) respectively. The second lifter (13) has a longitudinal cut-out (13C) extending to the transverse slot (13B) of the second lifter (13) to allow the second eccentric portion (10B) to enter the transverse slot (13B).

摘要： A valve opening/closing timing control device capable of quickly determining attainment of an intermediate locked phase includes: an intermediate lock mechanism capable of switching between a locked state in which a lock member provided in a drive-side rotary member protrudes and fits into a recess provided in a driven-side rotary member, thereby constraining a relative rotation phase to an intermediate locked phase, and an unlocked state in which the lock member withdraws from the recess, thereby releasing the constraint; a phase control unit that controls supply of a fluid to a retard chamber and discharge of the fluid from an advance chamber, or controls discharge of the fluid from the retard chamber and supply of the fluid to the advance chamber, such that the lock member attains the intermediate locked phase; and a determination unit that determines whether the lock member will attain the determination phase, when control has been performed such that the lock member moves toward a determination phase that has been set at a different position than the intermediate locked phase in the recess, after execution of control to supply the fluid to the retard chamber and discharge the fluid from the advance chamber, or control to discharge the fluid from the retard chamber and supply the fluid to the advance chamber. When the result of that determination is that the lock member will not attain the determination phase, the determination unit determines that the relative rotation phase is in the locked state.
