FIELD: engines and pumps.
SUBSTANCE: invention relates to an internal combustion engine having a variable compression ratio. Shaft (20) of variable compression degree mechanism control is coordinated with auxiliary shaft (25) of actuator device (1) via intermediate link (31). Housing (5) of device (1) of actuator has on its lower surface section (36) of oil filter seat, and locking section (37) is formed as a whole with section (36) of oil filter seat. Second lever (28) of auxiliary shaft (25) comes in contact with locking section (37) to determine the compression degree limit on the low compression side. Locking section (37) has high rigidity, since section (36) of oil filter seat, having high rigidity, and locking section (37) are combined together.
EFFECT: disclosed is an actuator device for an internal combustion engine with variable compression ratio (versions).
