CO The invention relates to a mechanical engineering & It can also be used in the gas distribution mechanisms of Eiay engines for reduced combustion. Known mezzaniems gas distribution & no internal combustion engines, containing a poppet valve with a ster), a rocker with a pressure surface interacting with a cam of the valve vapravdv through the intermediate segment, installed in the rocker arm with the possibility of rotation in the plane of rotation of the cam. valve closure. The aim of the invention is to expand the functionality of the timing mechanism by independently controlled and moments of closing and opening the valve. The goal is achieved by the fact that in the engine timing engine i of an internal combustion engine containing a plate chats and a valve with a rod, a rocker with a pressure surface interacting with a cam of a distribution shaft through an intermediate segment mounted in a yoke with a possibility of noi gate in the plane of rotation of the cam, the segment is made up of a composite of two parts, installed in the rocker arm, with the possibility of turning in the opposite anionic directions and equipped with adjustable ptanam K. elements. Fig. 1 shows a diagram of the flow of gas distribution; Fig, 2 "rocker; in fig. 3 is the same, top view} in FIG. 4 shows section A-A in FIG. 2. The engine timing mechanism for internal combustion engines contains a disk valve 1 with a stem 2, a rocker arm 3 with a pressure surface interacting with the cam 4 of the camshaft 5 through an intermediate segment 6, which is installed in the arm 3, can be rotated in the plane of rotation of the cam 4, Segmong Composed of two parts, installed in the rocker arm 3, can be rotated in opposite directions and provided with regulating elements. The regulating elements (elements 7 are made in all the screws matched by a worm gear with segments B. The device operates as follows. Segment 6, by means of the regulating element 7, moves around its axis of rotation, coinciding with the camshaft, into the rocker arm 3, changing the moment of contact with cam, and, therefore, change and the moment of opening (closing) of the valve. The adjustment of the moments in the latch is carried out independently of each other, the proposed valve timing mechanism allows you to set optimal s gazorassch eaelvnv on each operation of the engine, that is poevol facilitate optimal podbsf TIMING for newly design Mykh engines.
