Zusammenfassung:	An Oldham coupling includes an annular ring having a first side and a second side opposite to the first side, a first and a second engaging groove that are diametrically opposed and located on the first side, and a third and a fourth engaging groove that are diametrically opposed and located on the second side. The first and second engaging grooves are configured to be engaged with a first and a second engaging projection provided on a fixed element. The third and fourth engaging grooves are configured to be engaged with a third and a fourth engaging projection provided on an orbiting scroll. The first and third engaging grooves are located in a first angular sector, and the second and fourth engaging grooves are located in a second diametrically opposed angular sector of the annular ring, the first and second angular sectors have an opening angle less than 40°.
