摘要： A co-rotating scroll machine (1) for displacing and compressing or expanding a fluid, comprising a drive scroll (5a) comprising at least one drive scroll blade (18a), an idler scroll (5b) comprising at least one idler scroll blade (18b), a housing (2) comprising a scroll chamber (32) bounded by a first chamber end wall (11) and a second chamber end wall (13) and in which the drive scroll and the idler scroll are received, the drive scroll and the idler scroll being rotatable within the scroll chamber, a low-pressure port (3), a first high-pressure port (4), a drive shaft (20), an idler shaft (21), and a coupling mechanism. The drive scroll (5a) is coupled to the drive shaft (20) and rotatable about an axis (Ad) of the drive shaft (20), the idler scroll (5b) is coupled to the idler shaft (21) and rotatable about an axis (Ai) of the idler shaft (21), the axes (Ad, Ai) of the drive shaft (20) and the idler shaft (21) are parallel and offset, and the coupling mechanism is configured to transmit a force from the drive scroll (5a) to the idler scroll (5b) to cause the drive scroll (5a) and the idler scroll (5b) to rotate in the same direction and with the same speed, a variable volume pump chamber (19) being formed between a pair of contacting said at least one drive scroll blade (18a) and said at least one idler scroll blade (18b). The at least one drive scroll blade and at least one idler scroll blade (18a, 18b) extend in an axial direction from a first axial edge (50a, 50b) to a second axial edge (51a, 51b), an axial length (L5a) of the drive scroll blade (18a) being equal to an axial length (L5b) of the idler scroll blade (18b), the first axial edge adjacent and in sealing proximity to the first chamber end wall (11) and the second axial edge adjacent and in sealing proximity to the second chamber end wall (13), such that a pressure in the variable volume pump chamber (19) is exerted on both the first chamber end wall (11) and the second chamber end wall (13).

摘要： An element for compressing or expanding a gas comprising:
- a rigid housing (2) containing an internal chamber;
- a rotor (3a, 3b) situated in the internal chamber and comprising a rotor shaft (4a, 4b);
- one or more bearings (7) in which the rotor shaft (4a, 4b) is bearing-supported, wherein the rotor (3a, 3b) with its rotor shaft (4a, 4b) is rotatably mounted with respect to the housing (2) by means of these bearings (7), wherein the rotor (3a, 3b) is mounted with one or more clearances with respect to a wall (5) of the internal chamber.
The element (1) is provided with a separate yielding component (10), not directly attached to the rotor (3a, 3b), and which is positionally adjustable with respect to the housing (2) in such a way that at least one of the clearances can be acted upon.
