    Abstract: PROBLEM TO BE SOLVED: To obtain a blade tensioner, having the action of providing continuous tension to a chain. SOLUTION: The blade tensioner, having a tension arm 18 with an end 22, a face 30 fixed on the tension arm 18 with the extending part longer than the end 22, and a blade spring 36 fixed on the tension arm 18 with the extending part longer than the end 22 and compressing the face 30 to a chain 16. When the chain 16 wears out and loosens, the face 30 maintains compression to the chain 16, by curving the both extending parts longer than the end 22 of the face 30 and the blade spring 36 along the tension arm 18, and the compression of the blade spring 36 provides the chain 16 with continuous tension.

    Abstract: PROBLEM TO BE SOLVED: To provide a variable cam shaft timing system having a rotor and a housing locked and unlocked in the most advance position, the most retard position and the intermediate position between them. SOLUTION: This system is provided with the rotor 22 fixed to a cam shaft 14 so as not to vibrate to the cam shaft 14, the housing 68 enclosing the rotor 22, rotating with the rotor 22 and the cam shaft 14, and vibrating to the rotor 22 and the cam shaft 14 between the most retard position and the most advance position, a locking means for removably locking the rotor 22 and the housing 68, and a control means for controlling the vibration of the rotor 22 to the housing 68.

    IPC: F01L1/34 ,  F01L1/344

    Abstract: PROBLEM TO BE SOLVED: To provide a multi-mode VCT system capable of being kept at any position between the most front position and the most back position. SOLUTION: This timing device comprises advance and retard chambers 24A and 24R, a pulse driving means, and a pressure driving means for interconnecting them. The pulse driving means comprises retard pulse means 50, 44, and 56 for conveying fluid from the chamber 24A to the chamber 24R under pulsation, and advance pulse means 52, 46, and 54 for conveying fluid from the chamber 24R to the chamber 24A under pulsation. The pressure driving means comprises retard pressure supplying means 34, 46, and 52 for supplying fluid to the chamber 24R, retard pressure discharging means 50, 44, 64, 180, and 32 for discharging fluid from the chamber 24A, advance pressure supplying means 34, 44, and 50 for supplying fluid to the chamber 24A, and advance pressure discharging means 52, 46, 66, 180, and 32 for discharging fluid from the chamber 24R.

    Abstract: PROBLEM TO BE SOLVED: To provide a variable cam shaft timing system adapted to continuously vary the position of a cam shaft relative to the position of a crankshaft. SOLUTION: This system is provided with a hub 40 fixed to the cam shaft 50, a housing 24 enclosing the hub 40, and vibrating to the hub 40 and the cam shaft 50, plural drive vanes 36 cooperating with the outer surface 42 of the hub 40, plural driven vanes 46 cooperating with the inner surface 32 of the housing 24 advance chambers 12 and retard chambers 14 alternately arranged, a locking means for preventing the relative motion between the housing 24 and the hub 40, and a vibration control means for controlling vibration of the housing 24 to the hub 40.

    IPC: F16H7/08

    Abstract: A hydraulic tensioner (100) is designed for low cost and ease of manufacturing. A housing (102) has a bore (104) and a sleeve member (105) received within the bore. A piston (130) is slidably received within the sleeve member, forming a high pressure fluid chamber (180) with the sleeve member. The housing can be constructed of inexpensive materials such as aluminum or plastic. The piston and sleeve member are constructed of drawn metal. The housing may be formed by injection molding. The sleeve member and other components of the tensioner may be assembled within the tensioner by inserting them into the mold during the injection molding process.
