Claims

[Claims for Utility Model Registration] 1. A first scroll member in which a spiral body is disposed on one surface of a plate, and a second scroll member in which a spiral body is similarly disposed on one surface of a plate. The two spiral bodies are arranged at different angles from each other and the side walls of both spiral bodies are in contact with each other, and the first scroll member is caused to revolve on a circular orbit so that the first scroll member is closed between the two spiral bodies. The fluid is taken in while forming a plurality of spaces, the closed space is moved by one center point along with the movement of the first scroll member, and the volume is reduced. In a scroll type compressor that performs a unidirectional fluid compression action with a decrease in a control plate that is slidable in the axial direction is provided in the mutual spacing, and a drive means is provided for moving the control plate in a predetermined direction; 4. A scroll compressor characterized in that the intake volume of the sealed space is made variable by bringing the control plate into contact with or away from the spiral body of the first scroll member. 2. The mutual spacing is determined by shortening the wall height of the spiral body of the first scroll member and lowering one side of the plate body of the second scroll member. 3. The scroll type compressor according to claim 1, which is a scroll type compressor according to claim 1, characterized in that the second scroll member has a bottom having high wear resistance on one surface of the plate. Scroll type compressor according to claim 1 or 2, characterized in that the scroll compressor is equipped with a plate, and the control plate is a part of the bottom plate. The driving means has a pressure transmission path for transmitting the pressure of the compressed fluid to the back surface of the control plate, as claimed in any one of claims 1 to 3 of the utility model registration claim. Scroll type compressor. 5. The scroll type compressor according to claim 4, wherein the pressure transmission path has a valve that can turn on and off pressure transmission. 6. The driving means includes a spring that biases the control plate toward the plate of the second scroll member. Scroll type compressor according to item 5.
