摘要：
A rotary valve is used as a suction valve mechanism of a compressor. The rotary valve rotates integrally with a drive shaft to selectively open or close a suction passage of refrigerant gas from a suction chamber to a compression chamber in accordance with relative positions of the suction communicating passage and the suction guiding groove. An outer surface of the rotary valve directly slides on an inner surface of a valve accommodating chamber formed in a cylinder block, thereby constituting a slide bearing surface. The slide bearing surface rotatably supports the rear end of the drive shaft on housings. Accordingly, a piston type compressor which is comfortably used, inexpensively manufactured, and has high compression efficiency is provided.
摘要（中）：
旋转阀用作压缩机的吸气阀机构。 旋转阀与驱动轴一体地旋转，以根据吸入连通通路和吸引导向槽的相对位置选择性地将制冷剂气体的吸入通道从吸入室打开或关闭到压缩室。 旋转阀的外表面在形成于气缸体中的阀容纳室的内表面上直接滑动，构成滑动轴承面。 滑动轴承表面可旋转地支撑驱动轴在壳体上的后端。 因此，提供了一种舒适地使用，廉价制造并且具有高压缩效率的活塞式压缩机。
