    • A coffee brewer of the type having an outer fixed cylindrical tube and a fixed piston within the tube. A sliding cylinder slides in sealing contact between the outer cylinder and the piston. The sliding cylinder has a filter at the top thereof. A frame mounts the piston head and the outer cylindrical tube, and motor means are mounted on the frame with a pair of rotors rotatably mounted on the frame, one on either side of the outer cylindrical tube about a lateral axis at right angles to the axial axis of the outer and sliding cylindrical tubes. Each rotor includes an arcuate segment with gear teeth on the periphery thereof. Gear means connect the motor to the rotors for rotating the rotors, and a cam connector connects the sliding cylinder to the rotors for sliding movement of the sliding cylindrical tube during the brewing cycle. A spring mounted sweeper blade extends between a pair of arms, one on either side of the outer cylindrical tube, for sweeping the top of the sliding cylindrical tube and, therefore, the filter. A pour spout is mounted on the frame and is connected to a flexible tube communicating with the sliding cylinder for pouring the coffee from the interior of the sliding cylinder when the appropriate position is reached in the brewing cycle.
    • 这种类型的咖啡冲泡器具有外部固定圆柱形管和管内的固定活塞。 滑动气缸在外筒和活塞之间的密封接触中滑动。 滑动缸在其顶部具有过滤器。 框架安装活塞头和外圆柱形管,并且电机装置安装在框架上,一对转子可旋转地安装在框架上,一个在外圆筒管的任一侧上围绕与轴向成直角的横向轴线 外圆滑管和滑动圆柱管的轴线。 每个转子包括在其周边上具有齿轮齿的弧形段。 齿轮装置将马达连接到转子上以旋转转子,凸轮连接器将滑动缸连接到转子上,用于在冲泡循环期间滑动圆柱形管的滑动运动。 弹簧安装的清扫刀片在一对臂之间延伸,一对在外圆柱形管的任一侧上,用于扫掠滑动圆柱形管的顶部,因此用于过滤器。 倾倒式喷口安装在框架上,并且连接到与滑动气缸连通的柔性管,用于在冲泡循环中达到适当位置时从咖啡滑动筒的内部注入咖啡。
