Scroll compressor and process for compressing a gaseous fluid with the scroll compressor

A scroll compressor for compressing a gaseous fluid comprising:

• a non-moving stator with a base plate and a spiral-shaped wall that extends from the base plate;
• at least one outlet;
• and
• a moving orbiter with a base plate and a spiral-shaped wall that extends from the base plate, wherein the base plate of the stator and the base plate of the orbiter are arranged relative to one another in such a way that the wall of the stator and the wall of the orbiter interlock with one another and create closed working chambers, wherein volumes and positions of the working chambers are changed in reaction to a rotary movement of the orbiter, wherein the wall of the stator and the wall of the orbiter are configured in such a way that a first end chamber of the working chambers and a second end chamber of the working chambers of a compression path, as well as an intermediate chamber arranged between the first end chamber and the second end chamber at inner ends of the wall of the stator and the wall of the orbiter are formed in an area of the at least one outlet based on a rotation angle of the orbiter, and wherein at least one of the wall of the stator and the wall of the orbiter in an area of the inner ends is configured in such a way that a gap is created between the wall of the stator and the wall of the orbiter as a flow path from the intermediate chamber to at least one of the first end chamber and the second end chamber, wherein a degree of opening of the flow path is dependent on the rotation angle of the orbiter, wherein the at least one of the wall of the stator and the wall of the orbiter is constructed with a wall thickness reduced in the area of the inner ends between two sections in order to increase an original volume of the intermediate chamber, wherein the at least one of the wall of the stator and the wall of the orbiter is constructed in such a way that the wall thickness of the at least one of the wall of the stator and the wall of the orbiter decreases continuously from a first one of the two sections moving towards a second one of the two sections and is then increased in an area of the second one of the two sections to an original thickness at the second one of the two sections.

A process for compressing a gaseous fluid using a scroll compressor, the scroll compressor comprising:

• a non-moving stator with a base plate and a spiral-shaped wall that extends from the base plate;
• at least one outlet;
• and
• a moving orbiter with a base plate and a spiral-shaped wall that extends from the base plate, wherein the base plate of the stator and the base plate of the orbiter are arranged relative to one another in such a way that the wall of the stator and the wall of the orbiter interlock with one another and create closed working chambers, wherein volumes and positions of the working chambers are changed in reaction to a rotary movement of the orbiter, wherein the wall of the stator and the wall of the orbiter are configured in such a way that a first end chamber of the working chambers and a second end chamber of the working chambers of a compression path, as well as an intermediate chamber arranged between the first end chamber and the second end chamber at inner ends of the wall of the stator and the wall of the orbiter are formed in an area of the at least one outlet based on a rotation angle of the orbiter, and wherein at least one of the wall of the stator and the wall of the orbiter in an area of the inner ends is configured in such a way that a gap is created between the wall of the stator and the wall of the orbiter as a flow path from the intermediate chamber to at least one of the first end chamber and the second end chamber, wherein a degree of opening of the flow path is dependent on the rotation angle of the orbiter, wherein in a certain range of the rotation angle of the orbiter with an arrangement of the stator and the orbiter a gap is opened between the wall of the stator and the wall of the orbiter as a flow path from the intermediate chamber to the at least one of the first end chamber and the second end chamber, whose degree of opening is dependent on the rotation angle of the orbiter, wherein the intermediate chamber is closed at a rotation angle of 0° with the arrangement of the stator and orbiter.
