内燃机
摘要：
一种内燃机，内燃机(100)的汽缸体移动机构(3)具备：一根控制轴(30)，其与曲轴(10)平行地延伸且由曲轴箱(1)和汽缸体(2)中的一方支承，并且具有主轴部(30a)和在从该主轴部(30a)的轴心偏心了预定量的位置具有轴心的偏心部(30b)；连结部件(31)，其一端部安装于偏心部(30b)，并且其另一端部安装于曲轴箱(1)和汽缸体(2)中的另一方，用于将曲轴箱(1)和汽缸体(2)中的另一方与控制轴(30)连结；以及致动器(32)，其用于使控制轴(30)在预定的旋转范围内向两个方向旋转，使偏心部(30b)的轴心以主轴部(30a)的轴心为中心地在汽缸体(2)的相对移动方向上摆动。
摘要（英）：

An internal combustion engine including a block movement mechanism comprising a single control shaft extending in parallel with the crankshaft and supported by one of a crankcase and cylinder block and having a main shaft part and eccentric parts with an axial center at a position offset by a predetermined amount from the axial center of the main shaft part, coupling members with one end parts attached to the eccentric parts and the other end parts attached to the other of the crankcase and cylinder block and connecting the control shaft and the other of the crankcase and cylinder block, and an actuator making the control shaft rotate in both directions within a predetermined range of rotation so as to make the axial center of the eccentric parts swing about the axial center of the main shaft part in the direction of relative movement of the cylinder block.
