    • A compact cryocooler includes a gas compression piston (304) supported for reciprocal linear translation along a first longitudinal axis (308) and a gas displacing piston (362) supported for reciprocal linear translation along a second longitudinal axis (366). The first longitudinal axis (308) and second longitudinal axis (366) are substantially orthogonal. A rotary motor (302) rotates a rotor (324) and associated motor shaft (320) about a motor rotation axis (328) disposed substantially parallel with the second longitudinal axis (366). Motor shaft (320) first and second mounting features (336, 340) traverse first and second eccentric paths around the motor rotation axis. A first drive coupling couples the first mounting feature (336) with the gas compression piston (304) and delivers a reciprocal linear translation along the first longitudinal axis (308) thereto. A second drive coupling couples the second mounting feature (340) with the gas displacing piston (362) and delivers a reciprocal linear translation along the second longitudinal axis (366) thereto.
    • 紧凑型低温冷却器包括被支撑用于沿着第一纵向轴线(308)往复线性平移的气体压缩活塞(304)和被支撑用于沿第二纵向轴线(366)往复线性平移的排气活塞(362)。 第一纵轴(308)和第二纵轴(366)基本正交。 旋转马达(302)围绕设置成基本上平行于第二纵向轴线(366)设置的马达旋转轴(328)旋转转子(324)和相关联的马达轴(320)。 电动机轴(320)第一和第二安装特征(336,340)围绕电动机旋转轴线绕过第一和第二偏心路径。 第一驱动联接器将第一安装特征(336)与气体压缩活塞(304)耦合,并沿着第一纵向轴线(308)向其递送往复的线性平移。 第二驱动联接器将第二安装特征(340)与排气活塞(362)联接,并沿着第二纵向轴线(366)递送往复的线性平移。
