    • A two-cylinder air compressor has a motor with a through drive shaft. Identical housings are provided at each end of a cylindrical spacer sleeve that surrounds the motor. The housings include cylinder housing extensions each of which mounts a cylinder sleeve, a valve plate, and a head. The heads are part of a one-piece cylinder head member. Wobble pistons are mounted on each end of the motor shaft and operate in the cylinder sleeves. The cylinder sleeves rest on a floor in the housing which has integrally formed passages for cooling air to circulate around the cylinder sleeves. The one-piece cylinder head member includes integral tubes connecting the heads. The integral tubes span the distance between the heads and are spaced from the outside of the spacer. The housings may be joined by through bolts or without bolts by press fitting the bearings in the housing, press fitting the housings to the spacer sleeve, and press fitting the motor shaft into the bearings. The one-piece cylinder head serves as the final retention member, clamping the housings axially while maintaining radial orientation.
    • 双缸空气压缩机具有带有通过驱动轴的电动机。 在围绕电机的圆柱形间隔套筒的每一端设有相同的外壳。 壳体包括气缸壳体延伸部,每个壳体延伸部安装有气缸套筒,阀板和头部。 头部是一体式气缸盖构件的一部分。 摆动活塞安装在电机轴的每一端,并在气缸套中运行。 气缸套安装在壳体中的地板上,该底板具有一体形成的通道,用于冷却空气以围绕气缸套筒循环。 一体式气缸盖构件包括连接头部的整体管。 整体管跨越头部之间的距离并且与间隔件的外部间隔开。 外壳可以通过螺栓连接,也可以通过将轴承压入外壳中而不用螺栓连接,将外壳压配合到间隔套上,并将电机轴按压到轴承中。 一体式气缸盖用作最终的保持构件,在保持径向定位的同时轴向夹紧壳体。
