    Abstract: PROBLEM TO BE SOLVED: To shorten the whole length of a variable camshaft timing system to prevent a fluid leakage.
    SOLUTION: This variable camshaft timing system comprises a variable camshaft timing phaser having advance chambers 102 and retard chambers 107 and mounted to a camshaft 126, an advance line 108 in fluid communication with the advance chambers 102 and leading to the camshaft 126, and a retard line 110 in fluid communication with the retard chambers 107 and leading to the camshaft 126. A cam bearing having ports aligned with the advance line 108 and the retard line 110 is surrounded by a sleeve 236 having the same thermal expansion coefficient, and a control system 130 arranged separately from the phaser has a valve for selectively impeding and unidirectionally allowing the flow of the fluid from the port of the advance line 108 or retard line 110.

    Abstract: PROBLEM TO BE SOLVED: To set a pressure level for releasing a locking pin higher than a pressure level for retaining the lock pin in a variable camshaft timing phaser.
    SOLUTION: The variable camshaft timing phaser comprises: a rotor 2 which is connected to a camshaft and of which relative angular position with respect to a housing 1 can be changed; the locking pin 10 slidably located in a hole 17 of the housing 1; the locking pin having a tapered inner top end portion 18 which can be engaged with a tapered recess 19 of the rotor 2 so that the locking pin can move within the hole 17, between the locking position where the relative angular position of the rotor 2 with respect to the housing 1 is locked when the inner top end portion 18 is engaged with the recess 19 and the lock releasing position; a spring 21 for biasing the locking pin 10 toward the locking position; and a movable ball-like or cylindrical piston 14 which allows fluid to flow into the recess 19 or inhibits the fluid from flowing into the recess 19. The cross-sectional area of the piston 14 is smaller than that of the outer diameter of the locking pin main body.

    Abstract: PROBLEM TO BE SOLVED: To prevent noise from occurring at the time of running of a rotor by restraining movement of a vane in a chamber.
    SOLUTION: Cavity of the housing 1 is divided by the vane 5 of the rotor 2 into chambers 6, 7. The passages 12, 13 connecting the chambers 6, 7 are provided to facilitate oscillation of the vane 5 in the cavity. A valve 4 is disposed to form at least two openings for fluid flowing between the chambers 6, 7, and being disposed to keep at least one opening closed. A bypass 30 is disposed to stop or slow down the rotation between the housing 1 and the rotor 2, thereby allowing a locking mechanism to lock the housing 1 and the rotor 2 together independent of fluid flow. The bypass 30 is disposed apart by a predetermined distance 32 from a passage 13a connecting the chamber 6 to the chamber 7.

    Abstract: PROBLEM TO BE SOLVED: To provide a variable cam timing phase device provided with a plurality of integral type check valves. SOLUTION: In this variable cam timing phase device, a spool valve 204 has a spool 209 having two lands and the check valves 228a, 228b. When the spool is at a first position, fluid from an advance chamber 208 passes through a port into a hole surrounding a spindle part at the center of the spool valve and flows by passing through a port into a passage communicating with a retard chamber and the check valves. When the spool is at a second position, fluid from the retard chamber 210 passes through the port into the hole surrounding the spindle part at the center of the spool valve and flows by passing through a port into a passage communicating with the advance chamber and the check valves. When the spool is at a third position, a passage into the port of the spool valve from the advance chamber is closed, and a passage into the port of the spool valve from the retard chamber is closed.

    Abstract: PROBLEM TO BE SOLVED: To provide a variable camshaft timing system which reduces vibration and noise resulting from the air mixed in a chamber. SOLUTION: The variable camshaft timing system is provided with a rotor 2 having a vane 5 which divides the cavity within a housing 1 into first and second chambers 6, 7. Passages 12, 13 which connect the first and the second chambers 6, 7 to each other and facilitate vibration of the vane 5 within the cavity by transporting fluid between the first and the second chambers 6, 7, are provided in the rotor 2. Moreover, the variable camshaft timing system is provided with a lock pin 10 which is substantially located in a cell 17 of the housing 1 so as to lock the housing 1 and the rotor 2 independently of the flow of the fluid without being influenced by the relative rotation, and at least one vent path 18 which is located between either of the first and the second chambers 6, 7 and the cell 17 of the housing 1 so as to discharge the air within the chamber 6 or 7, thereby reducing the noise.

    Abstract: PROBLEM TO BE SOLVED: To lock a relative position of a rotor and a housing in the operation without generating the relative vibrating motion between the rotor and the housing. SOLUTION: This variable camshaft timing phaser 10 is provided with the rotor 12 selectively movable between an advance position and a retard position to the housing 14. The rotor has a vane 20 received by an advance part 18A and a retard part 18R. Pressurized oil is selectively introduced into the advance part or the retard part, and simultaneously discharged from the retard part or the advance part. When a spool is located on a neutral position by a locking pin 48 axially movably accommodated in a passage 50 of the rotor, the relative position of the rotor and the housing is locked on a predetermined position. The locking pin is elastically energized toward a locking position by a spring 52, and is urged away from the locking position by the pressurized oil from a pressurization source.
