Description of the Related Art As shown in FIGS. 3 and 4, a conventional hermetic compressor includes an electric motor element consisting of a stator 2 and a rotor 3 inside a cylindrical hermetic container 1, and a shaft 4 driven by this electric motor element. Compressor elements driven through the compressor elements are respectively arranged. This compressor element includes a cylindrical piston 6 and a piston 5.
A cylindrical cylinder 6 that stores the
An upper bearing 7 and a lower bearing 8 are provided to close openings at both ends of the cylinder 6, and the cylinder 6 has a vane groove 10 in which a vane 9 is housed, one end of which contacts the piston 5 and the other end of which is pressed by a spring. The configuration is equipped with the following.
そして前記ベーン９の摺動方向寸法りは一般に次の様な
範囲で設計されている。The dimensions of the vane 9 in the sliding direction are generally designed within the following range.

機要素部内径を電動機要素部内径より大きくしたもので
ある。Means for Solving the Problems In the present invention, the back of the bevel groove of the cylinder is made to protrude in the direction of the outer diameter, and the inner diameter of the compressor element of the closed container is made larger than the inner diameter of the motor element in order to accommodate the cylinder. It is something.
作 用
圧縮機要素のベーンは、圧縮室と吸入室の圧力差分の荷
重を受ける。従ってこの荷重に対しベーンとシリンダー
間でＦｌ、Ｆ２の荷重が発生する。Working The vanes of the compressor element are loaded by the pressure difference between the compression chamber and the suction chamber. Therefore, in response to this load, loads Fl and F2 are generated between the vane and the cylinder.
この関係式を次に示す。This relational expression is shown below.
上式よりベーン長さしを長くすればＦｌ、Ｆ２は小さく
なってくる。From the above equation, if the vane length is increased, Fl and F2 will become smaller.
つまシペーン長さを長くすることを可能にすることによ
り、ベーンとシリンダー間の荷重を低減させることがで
きる。By allowing the blade length to be increased, the load between the vane and the cylinder can be reduced.
