[Means for solving problems]
The present invention is rotatably housed between a cylinder, main bearings and sub-bearings located at both ends of the cylinder, and the main bearing and the sub-bearings, and is fitted on a crank rotation shaft having an eccentric portion in the cylinder. A vane groove composed of a roller that rotates eccentrically, a main vane groove provided in the cylinder, and a guide vane groove provided in communication with the main vane groove in at least one of the main bearing and the sub bearing. A compression mechanism unit having a vane that reciprocates in the vane groove, comes into contact with the roller, and divides the inside of the cylinder .
And an electric drive unit for driving the previous Symbol compression mechanism,
And a sealed container housing the pre Symbol compression mechanism and an electric drive unit,
The rotary compressor is characterized in that the tip of the vane reciprocating in the guide vane groove protrudes longer than the tip of the vane reciprocating in the main vane groove.

本実施の形態は、図1の第1の実施の形態より、さらに信頼性及び効率を向上させるために、図1の第1の実施の形態におけるローラ7の外周部に、図7の(b)に示すように、クランク軸2の軸方向と平行にローラ溝27を形成したローラ26に、図7の(a)に示すように、ベーン19の円弧状先端がローラ溝2に勘合され構成されているものである。ベーン溝20及びベーン19は、第1の実施の形態と同様である。 In this embodiment, in order to further improve reliability and efficiency as compared with the first embodiment of FIG. 1, (b) of FIG. 7 is formed on the outer peripheral portion of the roller 7 in the first embodiment of FIG. as shown in), the roller 26 formed parallel to the roller grooves 27 and the axial direction of the crankshaft 2, as shown in FIG. 7 (a), the arc-shaped tip of the vane 19 is fitted into the roller grooves 2 7 It is configured. The vane groove 20 and the vane 19 are the same as those in the first embodiment.

尚、図3の(a)の第1の実施の形態では、主ベーン部23の厚みt1とガイドベーン部24の厚みt2が同じであるが、各々異なっていてもよいことは言うまでもない。また、図3の(b)に示す両側のガイドベーン部24の各々の幅h2、h2’も異なっていてもよく、上記同様の効果が得られる。 In the first embodiment of FIG. 3A, the thickness t1 of the main vane portion 23 and the thickness t2 of the guide vane portion 24 are the same, but it goes without saying that they may be different from each other. Further, the widths h2 and h2'of the guide vanes 24 on both sides shown in FIG. 3B may be different, and the same effect as described above can be obtained.
