摘要： An internal combustion engine includes an engine body having a chamber and an endless transmission member extended around and operatively engaged with a crankshaft and a cam shaft to transmit a rotation of the crankshaft to the cam shaft, the endless transmission member being movable along a closed path of travel in the chamber. A hollow mounting member is disposed in the chamber and has an upper open end and a lower tubular portion. The mounting member is fixed to the engine body through fastening elements secured to an upper portion of a peripheral wall of the mounting member. A tensioner device is disposed in the chamber and includes a tensioner member movably mounted on the engine body, and a hydraulic lock mechanism including a hollow cylinder and a plunger slidably received in the cylinder to define a hydraulic chamber in the cylinder. The cylinder is received in the hollow mounting member and snugly fitted in the lower tubular portion of the mounting member against movement. The mounting member and the cylinder defines an oil reservoir for holding oil therein, the hydraulic lock mechanism having passage through which the oil reservoir is in fluid communication with the hydraulic chamber. A check valve is connected to the passage for blocking it to prevent the plunger from moving in one direction along the cylinder. The plunger is movable in the other direction and operatively engaged with the tensioner member to hold it in sliding contact with the cam chain.

摘要： Intake and exhaust rotary valves (10, 10', 20; 110, 110', 120; 210, 210') are separately disposed in intake and exhaust passages (7, 7', 8, 8'; 107, 108) communicating with a combustion chamber (6; 106) in an internal combustion engine (1; 101), respectively, and are adapted to open and close the corresponding intake and exhaust passages. These rotary valves have spherical valve bodies (13, 13', 23; 113, 113', 123; 213, 213'). A valve operating system (30) for rotatively driving the valve bodies interlockingly with the movement of a piston (5; 105) in the internal combustion engine (1; 101) has drive shaft (34, 36; 134; 234) each of which is connected to the valve body through a connecting member (17, 18; 117, 118; 217, 218). In case a plurality of the intake and exhaust rotary valves are mounted, the valve bodies of the intake rotary valves as well as the valve bodies of the exhaust rotary valves are also interconnected through connecting members.

摘要： In an internal combustion engine in which intake and exhaust rotary valves each having a spherical valve body are controlled in opening and closing through a valve operating mechanism interlockingly with the movement of a piston, the intake and exhaust rotary valves (10, 20; 110, 120; 210, 220; 310, 310', 320, 320') respectively assume the fully opened positions to open intake and exhaust passages (7, 8; 107, 108; 207, 208; 307, 307', 308, 308'), during the intake and exhaust strokes of the engine (1; 101; 201; 301), and assume the fully closed positions during the explosion stroke. In the fully opened and closed positions, the intake and exhaust rotary valves (10, 20; 110, 120; 210, 220; 310, 310', 320, 320') are held at a stop state for a predetermined period of time by the intermittently operating function of the valve operating mechanism (30; 130; 230; 330).

摘要： A rotary valve system for an internal combustion engine having ball-type valves with through bores. The valves are driven by rocking cam mechanisms within passageways for controlling communication through intake and exhaust passages. Valve seats are arranged to either side of the valves such that sealing thereof may occur. In one embodiment, side cut portions are employed to allow either intake or exhaust gases to flow around the valve body as well as through the through bore when the valve is in the opening or closing orientation. In another embodiment, a through bore of square cross section is provided to increase flow during opening and closing thereof. In a third embodiment, a bias mechanism is employed to provide torque on the valves and drive mechanism to eliminate clearances such that impact between components will be reduced or eliminated.

摘要： Rocker arm clearance removing device wherein a hydraulic adjuster applies torque to a pressure bearing surface at right angles thereto on a curved outwardly extending pressure bearing arm of an eccentric cam which eccentrically supports the rocker arm. Rotation of the rocker arm resulting from the torque causes the rocker arm to come into pressure contact with a valve operating cam and an intake or exhaust valve. An engaging piece can be provided radially extending from the eccentric cam circumferentially spaced from the pressure bearing arm for engaging a swivel stop on the case of the hydraulic adjuster to limit swinging of the eccentric cam and rocker arm during assembly. An arm stopper can also be provided on the case of the hydraulic adjuster to prevent swinging of cam and rocker arm in the opposite direction during assembly.

First and second rocker arms respectively having arms abutting against the upper ends of the paired intake or exhaust valves are rockingly supported on a common support shaft which is fixed on the engine body while having an axis perpendicular to the operating directions of the valves. The first rocker arm is formed with a cylinder bore which is opened toward the second rocker arm to bear a plunger therein whereas the second rocker arm is formed with a guide bore which is opened toward the first rocker arm to fit the plunger therein. A hydraulic actuation chamber defined between the bottom portion of the cylinder bore and the rear end of the plunger is connected with an oil-pressure source through a hydraulic change-over valve for changing the supply and stop of the oil pressure to the actuation chamber. Either of the first or second rocker arm is formed with a cam slipper for sliding contact with a cam which is adapted to rotate in accordance with the run of the engine.

摘要： A valve disabling device has an engaging member and an urging member slidably disposed, respectively, in first and second axial bores formed within, respectively, first and second rocker arm means, one of which engages a valve actuating cam. The engaging member is displaceable within the first axial bore by means of pressure applying means, into the second axial bore for driving coupling of the first and second rocker arm means whereby a pair of inlet valves or exhaust valves corresponding to the first and second rocker arm means make valving motions in unison with each other, or out of the second axial bore for disconnection of the first and second rocker arm means from each other to disable part of the valves. Biasing means biases the engaging member into the second axial bore irrespective of operation of the pressure applying means, to correspondingly bias the urging member into a predetermined position where a portion thereof is projected out of the second axial bore. Retaining means holds the urging member in the predetermined position, thus drivingly coupling the two rocker arm means.

摘要： Method and apparatus for suspending valve actuation for use in an internal combustion engine is disclosed. Each of intake and exhaust valves is normally actuated by a rocker arm operated by a cam in synchronism with an engine operation. The rocker arm is supported at one end by a supporting member held to a cylinder head by means of a retaining member. The supporting member is selectively floatable with respect to the cylinder head to thereby effect suspension of valve operation. The supporting member is then held at a position where sliding contact between the rocker arm and the cam is prevented.
