Patent number: 9677649Abstract: A hydraulic auto-tensioner includes a plunger fitted to a bottom end portion of a rod so as to be slidable along a radially inner surface of a valve sleeve and a radially outer surface of the rod. The plunger has a bottom plate formed with a valve hole. A first leakage gap is defined between sliding surfaces of the plunger and the valve sleeve, and a second leakage gap of which the flow resistance is lower is defined between sliding surfaces of the plunger and the rod such that while the engine is running normally, oil in a pressure chamber leaks into a reservoir chamber through the second leakage gap, and when starting the engine by actuating a starter/generator, the plunger rises until the valve hole is closed so that oil in the pressure chamber leaks into the reservoir chamber through the first leakage gap.Type: GrantFiled: September 16, 2014Date of Patent: June 13, 2017Assignee: NTN CORPORATIONInventors: Satoshi Kitano, Tadahisa Tanaka, Eiji Maeno

Patent number: 7775923Abstract: A chain tensioner for use with a chain of a vehicle engine, includes a housing and a plunger slidably mounted in a cylinder chamber formed in the housing. The plunger is biased outwardly by a return spring mounted in a pressure chamber defined in the cylinder chamber by the plunger. A check valve is provided in the cylinder chamber to prevent backflow of hydraulic oil in the pressure chamber. A relief valve, provided in the plunger, opens above a relief pressure, thereby discharging hydraulic oil in the pressure chamber. An oil leakage clearance is defined between the plunger and the inner wall of the cylinder chamber. The relief pressure and the oil leakage clearance dimension are determined such that the tension in the chain is kept at such a level that vibrations of the chain are minimum at any temperature of hydraulic oil and at any engine revolution speed.Type: GrantFiled: June 28, 2005Date of Patent: August 17, 2010Assignee: NTN CorporationInventors: Seiji Sato, Satoshi Kitano, Hisashi Hayakawa
