Abstract: The present invention relates to a mechanism to prevent the incorrect assembly of an air vent disc in a hydraulic tensioner. The hydraulic tensioner includes a housing having a chamber. A hollow plunger is slidably positioned inside the chamber. The chamber contains a spring which biases the plunger in a protruding direction and an air vent disc provided inside the plunger. An air vent disc includes a first portion and a second portion. The first portion has a groove as a vent channel and a through-hole. The second portion has a central hole and a plurality of grooves extending radially and opening into the outer periphery of the vent disc. The outer diameter of the second portion is larger than the inner diameter of the aperture located at the upper end of the plunger tip.

Abstract: In an internal combustion engine with two cylinder banks, each cylinder bank having a cylinder head mounting thereon a valve operating device enabling both valve timing and valve lift characteristic to be varied, each valve operating device drives an engine valve through an eccentric cam, a substantially ring-shaped link, a rocker arm, a rod-shaped link, and a rockable cam, by rotation of a drive shaft. A control shaft varies the attitude of the rocker arm via a control cam by rotary motion thereof, in order to change a valve lift characteristic of the engine valve. As viewed in the same axial direction, a lifting direction of the rockable cam relative to a rotational direction of the drive shaft is the same in the two cylinder banks.

The engine provides a piston crown utilizing a connecting rod directly connected to the bottom surface of the piston crown. The piston crown is stabilized along the longitudinal cylinder axis by a rail guide. Connecting rods are provided which require less than one hundred eighty degrees (180null) circumference of a crankshaft pin for support so that a plurality of connecting rods can be associated with a single crankshaft pin. A tabbed bearing fits under the plurality of connecting rods to provide lubrication between the connecting rods and the crankshaft pin. Connecting rods are held to the crankshaft pin by a circular retaining ring. The engine provides a separate cylinder head and cylinder which are attached via a circular deformable retaining band to form a metal to metal seal. The engine provides an independent lubrication system in each engine.

Abstract: A tensioner, includes a hollow plunger guided in a cylinder for displacement in an axial direction and spring-loaded in a direction of a power transmitting element. A pressure chamber for receiving hydraulic fluid is defined by the cylinder and the plunger. Fitted interiorly of and being immobile with respect to the plunger is a control member which has a closed outer circumference, with a ring-shaped leakage gap formed by the plunger and the control member for passage of hydraulic fluid from the pressure chamber. The control member and the plunger have different coefficient of thermal expansion so that the leakage gap has dimensions which decrease as a temperature of the hydraulic fluid increases.

Abstract: In a variable valve operation control apparatus, an exhaust camshaft and an intake camshaft are held non-movably and movably in the axial direction, respectively. The intake camshaft has a profile varying in the axial direction. A timing pulley and the exhaust camshaft are fixed by a bolt to drive the exhaust camshaft by a crankshaft. A vane rotor is fixed to the exhaust camshaft, while a shoe housing and a gear are held rotatably relative to the vane rotor. Torque gears are provided on the intake camshaft to rotate with the intake camshaft. The rotational phase of the intake camshaft relative to the crankshaft is adjusted by hydraulically varying the rotational phase of the shoe housing relative to the vane rotor.
