ABSTRACT:
A variable cylinder device for internal combustion engines comprising an adjuster coupled to a rocker arm of an intake or exhaust valve lift mechanism so as to define a first rocking point of said rocker arm, the lash adjuster having a check ball which is pushed by the operation of a solenoid valve when the engine load is reduced to a small order, as the result of which the rocking point of the rocking arm shifts from the first rocking point to a second rocking point wherein the intake or exhaust valve maintains the closed position.
