旋转压缩机
摘要：
本发明的目的在于提供一种旋转压缩机，该旋转压缩机能够防止在上死点以后产生的微小空间的真空状态，并且能够抑制叶片滑动部的面压的上升，在气缸(4)内形成有气缸室(8)，气缸室(8)由上部轴承(5)和下部轴承(6)封闭，在气缸室(8)内配置有辊(7)，在气缸(4)形成有叶片滑动槽(12)，在叶片滑动槽(12)设置有叶片(13)和弹簧(14)，叶片(13)由弹簧(14)按压于辊(7)的外周面，气缸室(8)由叶片(13)分隔为高压侧压缩机和吸入孔(9)开口的低压侧压缩机，该旋转压缩机设置有切口部(20A)，该切口部(20A)的一端(21)位于叶片滑动槽(12)，另一端(22)位于将吸入孔(9)投影在气缸(4)的内周面(4a)上时的投影范围(X)内。
摘要（英）：

Disclosed is a rotary compressor which prevents vacuum conditions in microscopic gaps which occur from top dead centre and also controls the increase in contact pressure on the blade sliding section. The rotary compressor is comprised of a cylinder chamber (8) formed inside a cylinder (4), where the cylinder chamber (8) is blocked by an upper bearing (5) and a lower bearing (6), a roller (7) is disposed inside the cylinder chamber (8), a blade sliding groove (12) is formed on the cylinder (4), a blade (13) and a spring (14) are formed on the blade sliding groove (12), the spring (14) pushes the blade (13) against the outer surface of the roller (7), and the cylinder chamber (8) is divided by the blade (13) into a high-pressure side compression chamber and a low-pressure side compression chamber opened onto by an inlet aperture (9). One end of a notched section (20A) is positioned at the blade sliding groove (12), and the other extremity is positioned within a projection area X of the inlet aperture (9) on an inside surface (4a) of the cylinder (4).
