Abstract

PURPOSE: To provide an arrangement capable of changing the operational mode of suction valve with ease in an internal combustion engine of the type having a plurality of suction valves in one combustion chamber, by providing a plurality of cams having different profiles and bringing a rocker arm into selective contact with these cams.
CONSTITUTION: In changing operational mode of subsidiary suction valve 11 which is adapted for opening and closing subsidiary suction port 9 of a subsidairy intake system, potential energy is accumulated in compression springs 39, 41 by operating hydraulic cylinder 24 and rocker arm 19 is caused to shift instantaneously when the energy thus accumulated in compression springs 39, 41 exceeds the biasing force of spring 47 and ball 45. Resultantly, pad 19b of rocker arm 19 that has been held in contact, for instance, with cam 27a is shifted to a position where it is held in contact with another cam 27b alternatively. Here, in order to cause the above shifting of rocker arm 19 smoothly while pad 19b is held in contact with the circular base portion of cam, a rocker arm stopper 55 extending from the circular base portion of cam toward its rear side an considered in respect of rotation of cam is provided between the above two cams 27a and 27b for urging stopper 55 in the direction H by means of spring 61.
