    Abstract: The fluid machine includes a stationary member (6), a rotary member (5) and a labyrinth seal (9) including a succession of stationary steps (11) formed on the stationary member (6), and a succession of rotary steps (14) formed on the rotary member (5). The labyrinth seal (9) further includes a plurality of stationary recesses (18) each formed in a radial wall portion (12) of a respective stationary step (11), and a plurality of rotary recesses (21) each formed in a radial wall portion (16) of a respective rotary step (14). Each stationary step (11) defines a stationary projection (19) delimited by the stationary recess (18) formed on said stationary step (11), and each rotary step (14) defines a rotary projection (22) delimited by the rotary recess (21) formed on said rotary step (14). The axial width (Wr) of each of the stationary recesses (18) and of the rotary recesses (21) substantially equals the axial width (Wp) of each of the stationary projections (19) and of the rotary projections (22).

    Abstract: 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°.
