Problems solved by technology

[0012] Another object of the present invention is to provide a scroll device with an axial gap control function, which can effectively limit the axial movement of the fixed scroll during the compression process without relative movement with other components. Instead, it uses its flexible elements to prevent the fixed scroll from radial and rotational movement, thereby avoiding the collision between metal elements, improving the noise problem of the scroll device (compressor), and avoiding damage to the parts of the scroll device. And can improve the performance and reliability of the scroll device

Embodiment Construction

[0030] In order to further understand the features and technical content of the present invention, please refer to the following detailed description and accompanying drawings of the present invention.

[0031] see image 3 As shown, the present invention provides a scroll device with an axial gap control function, which can provide the scroll device with a fixed gap control function when the scroll device is shut down, thereby reducing friction in the startup phase and noise during operation . The scroll device includes: an orbiting scroll 3, a fixed scroll 4, a positioning ring 5, a pair of flexible elements 6, and a skeleton arranged in the casing (not shown) of the scroll device 1.

[0032] The frame 1 is disposed in the casing (not shown) of the scroll device, and the peripheral edge 11 of the frame 1 has a pair of notches 111 .

[0033] The pair of flexible elements 6 may be in the form of metal beams, which are arranged on the top side 12 of the frame 1 along the edg...

Abstract

The present invention discloses a scroll device with axial gap control function, in particular, it relates to a scroll device with the function capable of controlling axial gap between its fixed scroll and revolving scroll. Said scroll device includes the following several portions: a scroll device shell body; a skeleton which is placed in the interior of scroll device shell body and has a pair of reccesses; a pair of flexible elements which are placed in top side of said skeleton and spanned over said pair of reccesses, in the in the spanned place a hanging flexible section is formed; a perisporium equipped with a positioning ring with a pair of downwards-extended projection bodies, said pair of projection bodies is correspondent to said reccesses, and the projection bodies of said positioning ring are fixedly connected with the flexible section of said flexible elements; a fixed scroll a suspended from said positioning ring; and a revolving scroll which is fixed in said fixed scroll and is revolved.

Description

technical field [0001] The present invention relates to a scroll device with the function of controlling the axial gap, in particular to a scroll device with the function of controlling the axial gap between the fixed scroll and the orbiting scroll. Background technique [0002] Traditional scroll devices such as scroll compressors inevitably have two major deficiencies, which are described below. [0003] Firstly, when the traditional scroll compressor stops, since the fixed scroll contacts the orbiting scroll, the friction force will increase when starting. [0004] Its two, it is arranged on the flange, positioning pin and axial gap plate above the skeleton, is in order to centrally locate, and prevent the rotation of its fixed scroll. However, the existence of these flanges, positioning pins and axial gap plates will collide with each other when the scroll compressor is running, which not only produces noise, but also causes leakage in the chamber of the scroll compress...
