Abstract: An external combustion engine including a burner element, a heater head, a piston cylinder containing a piston, a cooler and a crankcase. The crankcase includes a crankshaft, a piston rod connected to the piston, a drive mechanism for converting the linear motion of the piston rod to rotary motion of the crankshaft and a linear cross-head bearing that is connected rigidly to the piston rod at one end and to the drive mechanism at the other end. Also the external combustion engine includes a piston clearance seal and a piston rod seal unit that has floating rod seals. The piston includes a inner dome to reduce axial heat transfer via radiation and convection.

Abstract translation: 一种外燃机，包括燃烧器元件，加热器头，容纳活塞的活塞缸，冷却器和曲轴箱。 曲轴箱包括曲轴，连接到活塞的活塞杆，用于将活塞杆的直线运动转换为曲轴的旋转运动的驱动机构和在一端刚性地连接到活塞杆的线性十字头轴承 另一端的驱动机构。 此外，外燃机还包括活塞间隙密封件和具有浮动杆密封件的活塞杆密封单元。 活塞包括一个内圆顶，以减少通过辐射和对流的轴向热传递。
