Description
本発明に係る回転式圧縮機は、密閉容器と、密閉容器に収容される環状のシリンダと、シリンダの内周面に沿って偏心回転するローリングピストンと、シリンダに径方向に設けられたベーン溝内を往復運動するベーンと、ベーンを付勢してベーンの先端部をローリングピストンに当接させるコイルばねであって、小径部および小径部よりも大径の大径部を有するベーンばねと、ベーンばねの大径部が内面に接触してベーンばねが固定されるスプリングガイドとを備え、スプリングガイドは、一端部が密閉容器に形成された開口部を介して密閉容器内に挿入され、シリンダに固定されており、ベーンばねは、スプリングガイドの内周面に形成されたねじ溝にベーンばねの大径部がねじ込まれてスプリングガイドに固定されているものである。 The rotary compressor according to the present invention includes a closed container, an annular cylinder housed in the closed container, a rolling piston that rotates eccentrically along the inner peripheral surface of the cylinder, and a vane groove provided in the cylinder in the radial direction. A vane that reciprocates inside, a coil spring that urges the vane to bring the tip of the vane into contact with the rolling piston, and a vane spring that has a small diameter portion and a large diameter portion that is larger than the small diameter portion. It is equipped with a spring guide in which the large diameter portion of the vane spring contacts the inner surface to fix the vane spring, and the spring guide is inserted into the closed container through an opening having one end formed in the closed container and a cylinder. The vane spring is fixed to the spring guide by screwing a large diameter portion of the vane spring into a thread groove formed on the inner peripheral surface of the spring guide .
圧入代は、ローリングピストン１３がベーン溝位相に位置したとき、つまりベーン１４が上死点位置にあるとき、のベーンばね１５のばね力で、ベーンばね１５の大径部１５ｂが溝部３５を径方向外側に滑る圧入代である。また、圧入代は、ローリングピストン１３がベーン溝位相から１８０°異なる位相に位置したとき、つまりベーン１４が下死点位置にあるとき、のベーンばね１５自体の慣性力で大径部１５ｂが溝部３５を滑らない圧入代である。 The press-fitting allowance is the spring force of the vane spring 15 when the rolling piston 13 is located in the vane groove phase, that is, when the vane 14 is in the top dead center position, and the large diameter portion 15b of the vane spring 15 has a diameter of the groove portion 35. It is a press-fitting allowance that slides outward in the direction. Further, the press-fitting allowance is such that when the rolling piston 13 is positioned 180 ° different from the vane groove phase, that is, when the vane 14 is at the bottom dead center position, the large diameter portion 15b is the groove portion due to the inertial force of the vane spring 15 itself. It is a press-fitting allowance that does not slip on 35.
ベーン１４はシリンダ１１の中心に向かう方向である前方の下死点位置とシリンダ１１から遠ざかる方向である後方の上死点位置との間を往復するものである。ベーンばね１５は、溝部３５に大径部１５ｂが嵌め込まれて圧入されている。大径部１５ｂの溝部３５に対する圧入代は、ローリングピストン１３がベーン溝位相に位置したときのベーンばね１５のばね力でベーンばね１５の大径部１５ｂが溝部３５の径方向外側に滑る圧入代、かつ、ローリングピストン１３がベーン溝位相から１８０°異なる位相に位置したときのベーンばね自体の慣性力でベーンばね１５の大径部１５ｂが溝部３５を滑らない圧入代に設定されている。 The vane 14 reciprocates between the front bottom dead center position in the direction toward the center of the cylinder 11 and the rear top dead center position in the direction away from the cylinder 11. The vane spring 15 has a large diameter portion 15b fitted into the groove portion 35 and press-fitted. The press-fitting allowance for the groove portion 35 of the large-diameter portion 15b is the press-fitting allowance in which the large-diameter portion 15b of the vane spring 15 slides outward in the radial direction due to the spring force of the vane spring 15 when the rolling piston 13 is located in the vane groove phase. Further , the large diameter portion 15b of the vane spring 15 is set to a press-fitting allowance that does not slip in the groove portion 35 due to the inertial force of the vane spring itself when the rolling piston 13 is positioned at a phase different from the vane groove phase by 180 °.
