Abstract:
(EN) The purpose of the invention is to eliminate the material loss caused by circular central parts which are discarded during manufacture of thrust plates and thereby reduce manufacturing costs. The invention provides a scroll fluid machine provided with: a fixed scroll having a first spiral body formed thereon; an oscillating scroll having a second spiral body corresponding to the first spiral body formed on the upper surface side thereof; a thrust plate provided on the lower surface side of the oscillating scroll and supporting the oscillating scroll such that the oscillating scroll can oscillate; and a frame accommodating the thrust plate and the oscillating scroll, the fixed scroll being provided at an upper part of the frame. The thrust plate is configured from a pair of circular arc-shaped plates arranged to constitute a ring.
(FR) L'invention a pour but d'éliminer la perte de matériau provoquée par des parties centrales circulaires qui sont jetées pendant la fabrication de plaques de butée, de façon à réduire les coûts de fabrication. Pour atteindre ce but, l'invention concerne une machine à fluide à volutes qui est pourvue : d'une volute fixe ayant un premier corps en spirale formé sur celle-ci ; d'une volute oscillante ayant un second corps en spirale correspondant au premier corps en spirale formé sur le côté de surface supérieure de celle-ci ; d'une plaque de poussée disposée sur le côté de surface inférieure de la volute oscillante et portant la volute oscillante de telle sorte que la volute oscillante peut osciller ; d'un cadre recevant la plaque de poussée et la volute oscillante, la volute fixe étant disposée sur une partie supérieure du cadre. La plaque de poussée est constituée par une paire de plaques en forme d'arc circulaire agencées de façon à constituer un anneau.
(JA) スラストプレートの製造時に廃棄される円形の中央部の材料ロスを無くし、製造コストを抑制する。スクロール流体機械は、第1渦巻体が形成された固定スクロールと、上面側に第1渦巻体に対応する第2渦巻体が形成された揺動スクロールと、揺動スクロールの下面側に設けられ、揺動スクロールを揺動自在に支持するスラストプレートと、スラストプレートおよび揺動スクロールが収容されるとともに上部に固定スクロールが設けられたフレームと、を備え、スラストプレートは、一対の円弧状プレートから構成され、一対の円弧状プレートが円環を構成するように配置された。
