Abstract: A valve gear device includes a stem having one end and the other end, an intake and exhaust valve connected to the other end of the stem and serving for opening and closing a port formed in a cylinder block of an internal combustion engine, a first spring biasing the stem toward a closing condition of the intake and exhaust valve, a cam, and a valve control device interposed between the cam and one end of the stem, the valve control device having a first member fitted in the cylinder block so as to be slidable along an axis of the stem and engaged with the cam, a second member receiving one end of the stem and movable within the first member relative thereto and a regulating device for permitting and preventing the movement of the second member relative to the first member. Such a structure enables that the top end of the stem is out of sliding engagement with any of related members, thereby preventing a friction wear of the top end of the stem.

Abstract: In a valve control device for an engine having a fuel supply means arranged in a suction passage, a valve arranged in an intake or exhaust passage, and a cam for driving the valve to open and close via a lifter, the lifter comprises a body which slides in a bore of a cylinder head of the engine, a cylinder arranged in the body and forming a sliding passage perpendicularly to an axial direction of the valve, a spool which is transferred between a first position and a second position in the sliding passage by hydraulic pressure, a slider arranged in the spool and having a driving force transmitting portion and a cavity portion, and a spring which holds the spool at the first position, and a stop valve is arranged between the fuel supply means and the valve in the suction passage in order to close the suction passage when the spool is at the first position. When the spool is held at the second position, the driving force of the cam is transmitted to the valve only via the body and the driving force transmitting portion of the slider, and never transmitted to the spool. Thus, a stabilized change-over operation of the valve control device is achieved.

Abstract: For preventing very small amplitude vibrations of the rod in a tensioner during high speed movement of a belt to be tensioned by the tensioner, a tube which is connected to a plunger which moves together with the rod is overlapped with a stationary member so as to define an annular clearance therebetween in an operating chamber of the tensioner. By filling an operating fluid in the clearance, shear strain is generated upon high speed movement of the plunger, which resists movement of the plunger.
