DOUBLE-ROW INTERNAL COMBUSTION ENGINE, WITH WOBBLE YOKE MECHANISM

The invention relates to the technical field of engine-building. In accordance with the invention an engine comprises a body (1) with four cylinders (4) , which are double-row installed, along axes (5) of which pistons (6) are in a reciprocal motion. The pistons (6) by means of rods (7) hindedly engage with yoke (15), which is hingedly installed in the body (1) with a possibility of rocking. The yoke (15), in turn, is hingedly connected to a wobbler (12) , which is installed by means of bearing (11) on a main shaft (12) of the engine with an inclination with respect to its rotary axis (3). When looking at the engine cutting, which is perpendicularly carried out with respect to the rotary axis (3) of the main shaft (2), a medium point of each hinge, providing with an engagement of the yoke (15) with the wobbler (12), is placed in an angle sector, which is formed between medium points of the hinges, providing with the engagement of the yoke (15) with rods (7). In case of the invention realization in accordance with one of its embodiments a connection of the yoke with the wobbler is accomplished by means of spherical of cardan hinge, and it gives a capability to move the yoke with respect to an oscillating center (13) of the wobbler, and it, in turn, provides with a capability of compression ratio change in the engine cylinders (4). In case of the invention realization in accordance with another its embodiment the main shaft (2) of the engine and the wobble-yoke unit are replaced out of zone of placing the cylinders (4) with an installation in the same or additional body formation, and the yoke is designed with an elongated axis of rocking and is provided with a rocker, which is connected with the pistons or with joint rods. L'invention concerne le domaine technique de la construction de moteurs. Conformément à la présente invention un moteur comprend un corps (1) avec quatre cylindres (4), qui sont disposés en deux blocs, les pistons (6) étant en mouvement alternatif le long des axes (5) de ces blocs. Les pistons (6), par l'intermédiaire de tiges (7), s'enclenchent en articulation avec le poussoir (15), qui est disposé en articulation dans le corps (1) avec une possibilité de se balancer. Le poussoir (15), à son tour, est relié par articulation à un trèfle (12), qui est installé au moyen d'un palier (11) sur l'arbre principal (2) du moteur avec une inclinaison par rapport à son axe de rotation (3). Quand on regarde la coupe du moteur effectuée perpendiculair
