Abstract (en)
A fluid machine(1) comprises a rotating shaft (12) extending in a cylindrical body part (3) of a closed container (2) and rotatably supported via a bearing (16), an electric motor (6) that drives the rotating shaft (12) by energization thereof, and has a rotor (7) and a stator (8), a scroll unit (30) accommodated above the electric motor (6), a frame member (14) that supports the rotating shaft (12) via the bearing (16), and flow-direction restricting means (80) that restricts a direction of lubrication oil flowing downward toward the electric motor (6) from the scroll unit (30) to inhibit the lubrication oil supplied from the reservoir (23) to the bearing (16) from flowing toward the stator (8). The flow-direction restricting means (80) includes a guide member (82) fixed to a top surface (7a) of the rotor (7) and guiding the downward-flowing lubrication oil to the top surface (7a), and a discharge passage (84) for causing the lubrication oil guided to the top surface (7a) to flow to the reservoir (23).
